  • SQl server 2008 permission and encryption

    - by paranjai
    i have made columns in some of the tables encrypted in sql server 2008. Now as i am a db owner i have the access to encode and decode the data using the symmetric key and certificate. But some other users have only currently datareader and datawriter rights ,and when they execute any SP referring the logic which uses the key and certificate "User does has not right on the certificate to execute". What rights / exact permission should i grant them just to solve this problem

  • Implementing One-way Encryption in PHP

    <b>Webreference:</b> "To demonstrate one-way encryption in PHP, this article describes how to start building a secure online diary application. The one-way encryption will allow the diary to log a user in and generally encrypt the contents of the file that it loads."

  • close file with fopen() but file still in use

    - by Marco
    Hi all, I've got a problem with deleting/overwriting a file using my program which is also being used(read) by my program. The problem seems to be that because of the fact my program is reading data from the file (output.txt) it puts the file in a 'in use' state which makes it impossible to delete or overwrite the file. I don't understand why the file stays 'in use' because I close the file after use with fclose(); this is my code: bool bBool = true while(bBool){ //Run myprogram.exe tot generate (a new) output.txt //Create file pointer and open file FILE* pInputFile = NULL; pInputFile = fopen("output.txt", "r"); // //then I do some reading using fscanf() // //And when I'm done reading I close the file using fclose() fclose(pInputFile); //The next step is deleting the output.txt if( remove( "output.txt" ) == -1 ){ //ERROR }else{ //Succesfull } } I use fclose() to close the file but the file remains in use by my program until my program is totally shut down. What is the solution to free the file so it can be deleted/overwrited? In reality my code isn't a loop without an end ; ) Thanks in advance! Marco

  • Windows 7 ssh file server.

    - by Siriss
    Hello all- I have looked at the other posts, but have not quite found an answer I have a question about windows file sharing over SSH. I have copssh installed and it is working for Remote desktop connections. I have port 22 forwarded on my router etc. I connect from a Mac or Putty with this address: ssh -l copsshusername 3391:localhost:3389 [external ip] That works fine. I would like to configure Windows 7 to allow my ssh account that I use to login, access to certain shared folders. I have documents and videos and things that I would like to be able to download externally. I have done this before on Linux and a long time ago on XP, but I cannot figure out what I am missing on Windows 7. There is a designated SSH user that copssh uses to run the service and that I use to to login as. I have googled and googled and have not found a solution that does everything I need that is why I am turning here for ideas. I hope I am explaining this correctly. Thank you very much for your help!

  • Android: writing a file to sdcard

    - by Sumit M Asok
    I'm trying to write a file from an Http post reply to a file on the sdcard. Everything works fine until the byte array of data is retrieved. I've tried setting WRITE_EXTERNAL_STORAGE permission in the manifest and tried many different combinations of tutorials I found on the net. All I could find was using the openFileOutput("",MODE_WORLD_READABLE) method, of the activity but how my app writes file is by using a thread. Specifically, a thread is invoked from another thread when a file has to be written, so giving an activity object didn't work even though I tried it. The app has come a long way and I cannot change how the app is currently written. Please, someone help me? CODE: File file = new File(bgdmanip.savLocation); FileOutputStream filecon = null; filecon = new FileOutputStream(file); // bgdmanip.savLocation holds the whole files path byte[] myByte; myByte = Base64Coder.decode(seReply); Log.d("myBytes", String.valueOf(myByte)); bos.write(myByte); filecon.write(myByte); myvals = x * 11024; seReply is a string reply from HttpPost response. the second set of code is looped with reference to x. the file is created but remains 0 bytes

  • How do I remove encryption from a VMware Workstation 7 image?

    - by Chad
    I successfully encrypted a VM image and confirmed it still runs. I then closed the VM and reopened it and confirmed the encryption password was valid and worked. However, now I want to un-encrypt the VM. When I choose that option, it asks for "your password". I assume this means the password I created when I encrypted it. It doesn't work. I can still open the VM with the password and run it. But, it refuses to remove the encryption using that password. Am I missing something? Is there a password that I don't know about? Some details: I created this image (using standalone converter; physical machine source) I converted it to ACE Converted back to a normal VM (un-ACE'd it) Encrypted it Cannot remove the encryption but can open it and run it As you can see... I am exploring the VMware features. Thanks for any guidance you can give.

  • PHP file_put_contents File Locking

    - by hozza
    The Senario: You have a file with a string (average sentence worth) on each line. For arguments sake lets say this file is 1Mb in size (thousands of lines). You have a script that reads the file, changes some of the strings within the document (not just appending but also removing and modifying some lines) and then overwrites all the data with the new data. The Questions: Does 'the server' PHP, OS or httpd etc. already have systems in place to stop issues like this (reading/writing half way through a write)? i. If it does, please explain how it works and give examples or links to relevant documentation. ii. If not, are there things I can enable or set-up, such as locking a file until a write is completed and making all other reads and/or writes fail until the previous script has finished writing? My Assumptions and Other Information: The server in question is running PHP and Apache or Lighttpd. If the script is called by one user and is halfway through writing to the file and another user reads the file at that exact moment. The user who reads it will not get the full document, as it hasn't been written yet. (If this assumption is wrong please correct me) I'm only concerned with PHP writing and reading to a text file, and in particular, the functions "fopen"/"fwrite" and mainly "file_put_contents". I have looked at the "file_put_contents" documentation but have not found the level of detail or a good explanation of what the "LOCK_EX" flag is or does. The senario is an EXAMPLE of a worst case senario where I would assume these issues are more likely to occur, due to the large size of the file and the way the data is edited. I want to learn more about these issues and don't want or need answers or comments such as "use mysql" or "why are you doing that" because I'm not doing that, I just want to learn about file read/writing with PHP and don't seem to be looking in the right places/documentation and yes I understand PHP is not the perfect language for working with files in this way...

  • Multiple file descriptors to the same file, C

    - by Gigi
    I have a multithreaded application that is opening and reading the same file (not writing). I am opening a different file descriptor for each thread (but they all point to the same file). Each thread then reads the file and may close it and open it again if EOF is reached. Is this ok? If I perform fclose() on a file descriptor does it affect the other file descritptors that point to the same file?

  • File system implementation in MongoDB with GridFS

    - by Ralph
    I am working on two projects that will both implement a Webdav server backed by a MongoDB GridFS. In each case, there is the potential for the system to store tens of millions of files spread across thousands of hierarchical directories. I can come up with two different ways of storing the directory structure: As a "true" hierarchical file system, with directories containing the IDs (_id) of subdirectories and regular files. The paths will be separated by slashes (/) as in a POSIX-compliant file system. The path /a/b/c will be represented as a directory a containing a directory b containing a file c. As a flat file system, where file names include the slashes. The path /a/b/c will be stored as a single file with the name /a/b/c What are the advantages and disadvantages of each, with respect to a "real" folder-based file system?

  • How to install PHP-FPM and PHP on Ubuntu?

    - by Sanoj
    I have problems with installing PHP and in Ubuntu. I followed the instructions on the PHP-FPM site, PHP FastCGI Process Manager but when doing ../configure && make to compile PHP I got a lot of not found messages (listed below), and I don't know how to fix them. I tried both the Integrated compilation and Separate compilation but both compilations ends up with the same messages. Is there a solution or workaround?

  • File Sharing: User-created folders are read-only to others on Mac 10.6 Server

    - by Anriëtte Combrink
    Hi there We recently got a new Mac Mini Server with 10.6 Server on it. It has two 500GB volumes, one of which [Macintosh HD2 the extra one other than the boot disk] we are using to share our work files. I have added a user account for each user in the Users pane on Server Preferences, and all our staff (users added to the system) are added to a new group, called toolboxstaff. Now, when a user creates a new folder on this volume, folders are created with read-only access for everyone else besides the owner. How do I set it that when a user creates a folder, it creates it with RW access for the toolboxstaff group? Thanks in advance.

  • Windows 8.1 Will Start Encrypting Hard Drives By Default: Everything You Need to Know

    - by Chris Hoffman
    Windows 8.1 will automatically encrypt the storage on modern Windows PCs. This will help protect your files in case someone steals your laptop and tries to get at them, but it has important ramifications for data recovery. Previously, “BitLocker” was available on Professional and Enterprise editions of Windows, while “Device Encryption” was available on Windows RT and Windows Phone. Device encryption is included with all editions of Windows 8.1 — and it’s on by default. When Your Hard Drive Will Be Encrypted Windows 8.1 includes “Pervasive Device Encryption.” This works a bit differently from the standard BitLocker feature that has been included in Professional, Enterprise, and Ultimate editions of Windows for the past few versions. Before Windows 8.1 automatically enables Device Encryption, the following must be true: The Windows device “must support connected standby and meet the Windows Hardware Certification Kit (HCK) requirements for TPM and SecureBoot on ConnectedStandby systems.”  (Source) Older Windows PCs won’t support this feature, while new Windows 8.1 devices you pick up will have this feature enabled by default. When Windows 8.1 installs cleanly and the computer is prepared, device encryption is “initialized” on the system drive and other internal drives. Windows uses a clear key at this point, which is removed later when the recovery key is successfully backed up. The PC’s user must log in with a Microsoft account with administrator privileges or join the PC to a domain. If a Microsoft account is used, a recovery key will be backed up to Microsoft’s servers and encryption will be enabled. If a domain account is used, a recovery key will be backed up to Active Directory Domain Services and encryption will be enabled. If you have an older Windows computer that you’ve upgraded to Windows 8.1, it may not support Device Encryption. If you log in with a local user account, Device Encryption won’t be enabled. If you upgrade your Windows 8 device to Windows 8.1, you’ll need to enable device encryption, as it’s off by default when upgrading. Recovering An Encrypted Hard Drive Device encryption means that a thief can’t just pick up your laptop, insert a Linux live CD or Windows installer disc, and boot the alternate operating system to view your files without knowing your Windows password. It means that no one can just pull the hard drive from your device, connect the hard drive to another computer, and view the files. We’ve previously explained that your Windows password doesn’t actually secure your files. With Windows 8.1, average Windows users will finally be protected with encryption by default. However, there’s a problem — if you forget your password and are unable to log in, you’d also be unable to recover your files. This is likely why encryption is only enabled when a user logs in with a Microsoft account (or connects to a domain). Microsoft holds a recovery key, so you can gain access to your files by going through a recovery process. As long as you’re able to authenticate using your Microsoft account credentials — for example, by receiving an SMS message on the cell phone number connected to your Microsoft account — you’ll be able to recover your encrypted data. With Windows 8.1, it’s more important than ever to configure your Microsoft account’s security settings and recovery methods so you’ll be able to recover your files if you ever get locked out of your Microsoft account. Microsoft does hold the recovery key and would be capable of providing it to law enforcement if it was requested, which is certainly a legitimate concern in the age of PRISM. However, this encryption still provides protection from thieves picking up your hard drive and digging through your personal or business files. If you’re worried about a government or a determined thief who’s capable of gaining access to your Microsoft account, you’ll want to encrypt your hard drive with software that doesn’t upload a copy of your recovery key to the Internet, such as TrueCrypt. How to Disable Device Encryption There should be no real reason to disable device encryption. If nothing else, it’s a useful feature that will hopefully protect sensitive data in the real world where people — and even businesses — don’t enable encryption on their own. As encryption is only enabled on devices with the appropriate hardware and will be enabled by default, Microsoft has hopefully ensured that users won’t see noticeable slow-downs in performance. Encryption adds some overhead, but the overhead can hopefully be handled by dedicated hardware. If you’d like to enable a different encryption solution or just disable encryption entirely, you can control this yourself. To do so, open the PC settings app — swipe in from the right edge of the screen or press Windows Key + C, click the Settings icon, and select Change PC settings. Navigate to PC and devices -> PC info. At the bottom of the PC info pane, you’ll see a Device Encryption section. Select Turn Off if you want to disable device encryption, or select Turn On if you want to enable it — users upgrading from Windows 8 will have to enable it manually in this way. Note that Device Encryption can’t be disabled on Windows RT devices, such as Microsoft’s Surface RT and Surface 2. If you don’t see the Device Encryption section in this window, you’re likely using an older device that doesn’t meet the requirements and thus doesn’t support Device Encryption. For example, our Windows 8.1 virtual machine doesn’t offer Device Encryption configuration options. This is the new normal for Windows PCs, tablets, and devices in general. Where files on typical PCs were once ripe for easy access by thieves, Windows PCs are now encrypted by default and recovery keys are sent to Microsoft’s servers for safe keeping. This last part may be a bit creepy, but it’s easy to imagine average users forgetting their passwords — they’d be very upset if they lost all their files because they had to reset their passwords. It’s also an improvement over Windows PCs being completely unprotected by default.

  • fcgiwrap listening to a unix socket file: how to change file permissions

    - by user36520
    I have a web server (nginx) and a CGI application (gitweb) that is ran with fcgiwrap to enable Fast CGI access to it. I want the Fast CGI protocol to take place over a unix socket file. To start the fcgiwrap daemon, I run: setuidgid git fcgiwrap -s "unix:$PWD/fastcgi.sock" (this is a daemontools daemon) The problem is that my web server runs as the user www-data and not the user git. And fcgiwrap creates the socket fastcgi.sock with user git, group git and read only fort the non owner. Thus, nginc with the user www-data can't access the socket. Apparently, fcgiwrap is not able to select permissions of unix socket files. And this is quite annoying. Moreover, if I manage to have the socket file exists before I run fcgiwrap (which is quite difficult given I did not find any shell command to create a socket file), it quits with the following error: Failed to bind: Address already in use The only solution I found is to start the server the following way: rm -f fastcgi.sock # Ensure that the socket doesn't already exists (sleep 5; chgrp www-data fastcgi.sock; chmod g+w fastcgi.sock) & exec setuidgid git fcgiwrap -s "unix:$PWD/fastcgi.sock" Which is far from the most elegant solution. Can you think of anything better ? Thanks

  • Nautilus and file command in 11.04 don't show metadata for WebM files

    - by Pili
    The file-name extension .webm is used for media files using the WebM multimedia format, which consists of the WebM container (a subset of the Matroska container) and audio and video streams with independet enconding and quality settings. Description of the issue: For files in the WebM format, the program file says that files are raw data, instead of determining and displaying the real file-format, which is WebM. Besides, Nautilus doesn't display the technical metadata of files in this format. Why is the file program not displaying the file format for WebM files?

  • How to add extensions to a lot of files using content of each file?

    - by v8media
    I've got over 10,000 files that don't have extensions from older versions of the Mac OS. They're extremely nested, and they also have all sorts of strange formatting and characters. They don't have file types or creator codes attached to them any longer. A great deal of these files have text in the file that will let me determine extensions (for example Word.Document.8 is in every file created by that version of Word, and Excel.Sheet.8 in every file created with that version of Excel). I found a script that looks like it would work for one of these file types at a time, but it erases parts of filenames after nefarious characters, which is not good. find . -type f -not -name "." -print0 |\ xargs -0 file |\ grep 'Word.Document.8' |\ sed 's/:.*//' |\ xargs -I % echo mv % %.doc So, two questions from that: One is, should I clean the characters in the filenames first, or programmatically deal with those in the script in order to leave them the same? As long as I lose no information from the filenames, I don't see a problem cleaning out slashes and other problem characters. Also, if I clean the filenames, there are likely to be duplicates, so any cleaning script would have to add something like "-1" before the extension to make sure nothing gets lost. 2nd question is how do I change the script so that it will look for more than one file type at the same time and give each the proper extension? I'm not tied to this script, but it is understandable, which is a pro. Mac OS X 10.6 is installed on this file server, but I've got access to any recent versions of OS X. Thanks, Ian

  • Python file-io code listing current folder path instead of the specified

    - by Tom Brito
    I have the code: import os import sys fileList = os.listdir(sys.argv[1]) for file in fileList: if os.path.isfile(file): print "File >> " + os.path.abspath(file) else: print "Dir >> " + os.path.abspath(file) Located in my music folder ("/home/tom/Music") When I call it with: python test.py "/tmp" I expected it to list my "/tmp" files and folders with the full path. But it printed lines like: Dir >> /home/tom/Music/seahorse-gw2jNn Dir >> /home/tom/Music/FlashXX9kV847 Dir >> /home/tom/Music/pulse-DcIEoxW5h2gz This is, the correct file names, but the wrong path (and this files are not either in my Music folder).. What's wrong with this code?

  • How to know file type without extension

    - by Ayusman
    While trying to come-up with a servlet based application to read files and manipulate them (image type conversion) here is a question that came up to me: Is it possible to inspect a file content and know the filetype? Is there a standard that specifies that each file MUST provide some type of marker in their content so that the application will not have to rely on the file extension constraints? Consider an application scenario: I am creating an application that will be able to convert different file formats to a set of output formats. Say user uploads an PDF, my application can suggest that the possible conversion formats are microsoft word or TIFF or JPEG etc. As my application will gradually support different file formats (over a period of time), I want my application to inspect the input file instead of having the user to specify the format. And suggest to user the possible formats of output. I understand this is an open ended, broad question. Please let me know if it needs to be modified. Thanks, Ayusman

  • Read a file to multiple array byte[]

    - by hankol
    I have an encryption algorithm (AES) that accepts file converted to array byte and encrypt it. Since I am going to process a very big size files, the JVM may go out of memory. I am planing to read the files in multiple array byte. each containing some part of the file. Then I teratively feed the algorithm. Finally merge them to produce encrypted file. So my question is: there any way to read a file part by part to multiple array byte? I thought I can use the following to read the file to array byte: IOUtils.toByteArray(InputStream input). And then split the array into multiple bytes using: Arrays.copyOfRange(). But I am afraid that the first code that reads file to byte will make the JVM to go out of memory. any suggestion please ? thanks

  • VFS: file-max limit 1231582 reached

    - by Rick Koshi
    I'm running a Linux 2.6.36 kernel, and I'm seeing some random errors. Things like ls: error while loading shared libraries: libpthread.so.0: cannot open shared object file: Error 23 Yes, my system can't consistently run an 'ls' command. :( I note several errors in my dmesg output: # dmesg | tail [2808967.543203] EXT4-fs (sda3): re-mounted.

I'm the only one using it, and it's not visible to anyone outside the local network. # lsof | wc 16046 148253 1882901 # ps -ef | wc 574 6104 44260 I saw some documentation saying: file-max & file-nr: The kernel allocates file handles dynamically, but as yet it doesn't free them again. The value in file-max denotes the maximum number of file- handles that the Linux kernel will allocate. When you get lots of error messages about running out of file handles, you might want to increase this limit. Historically, the three values in file-nr denoted the number of allocated file handles, the number of allocated but unused file handles, and the maximum number of file handles. Linux 2.6 always reports 0 as the number of free file handles -- this is not an error, it just means that the number of allocated file handles exactly matches the number of used file handles. Attempts to allocate more file descriptors than file-max are reported with printk, look for "VFS: file-max limit reached". My first reading of this is that the kernel basically has a built-in file descriptor leak, but I find that very hard to believe. It would imply that any system in active use needs to be rebooted every so often to free up the file descriptors. As I said, I can't believe this would be true, since it's normal to me to have Linux systems stay up for months (even years) at a time. On the other hand, I also can't believe that my nearly-idle system is holding over a million files open. Does anyone have any ideas, either for fixes or further diagnosis? I could, of course, just reboot the system, but I don't want this to be a recurring problem every few weeks. As a stopgap measure, I've quit Firefox, which was accounting for almost 2000 lines of lsof output (!) even though I only had one window open, and now I can run 'ls' again, but I doubt that will fix the problem for long. (edit: Oops, spoke too soon. By the time I finished typing out this question, the symptom was/is back) Thanks in advance for any help. And another update: My system was basically unusable, so I decided I had no option but to reboot. But before I did, I carefully quit one process at a time, checking /proc/sys/fs/file-nr after each termination. I found that, predictably, the number of open files gradually went down as I closed things down. Unfortunately, it wasn't a large effect. Yes, I was able to clear up 5000-10000 open files, but there were still over 1.2 million left. I shut down just about everything. All interactive shells, except for the one ssh I left open to finish closing down, httpd, even nfs service. Basically everything in the process table that wasn't a kernel process, and there were still an appalling number of files apparently left open. After the reboot, I found that /proc/sys/fs/file-nr showed about 2000 files open, which is much more reasonable. Starting up 2 Xvnc sessions as usual, along with the dozen or so monitoring windows I like to keep open, brought the total up to about 4000 files. I can see nothing wrong with that, of course, but I've obviously failed to identify the root cause. I'm still looking for ideas, since I definitely expect it to happen again. And another update, the next day: I watched the system carefully, and discovered that /proc/sys/fs/file-nr showed a growth of about 900 open files per hour. I shut down the system's only NFS client for the night, and the growth stopped. Mind you, it didn't free up the resources, but it did at least stop consuming more. Is this a known bug with NFS? I'll be bringing the NFS client back online today, and I'll narrow it down further. If anyone is familiar with this behavior, feel free to jump in with "Yeah, NFS4 has this problem, go back to NFS3" or something like that.

  • How secure is the encryption used by Microsoft Office 2007?

    - by ericl42
    I've read various articles about Microsoft's Office 2007 encryption and from what I gather 2007 is secure using all default options due to it using AES, and 2000 and 2003 can be configured secure by changing the default algorithm to AES. I was wondering if anyone else has read any other articles or know of any specific vulnerabilities involved with how they implement the encryption. I would like to be able to tell users that they can use this to send semi-sensitive documents as long as they use AES and a strong password. Thanks for the information.

  • Full disk encryption on linux (ubuntu) w/o re-installing - possible?

    - by sa125
    Hi - I work at a company that takes security very seriously (like most). Our IT guy came in today to prepare us mentally to re-install our systems after he'll apply the new encryption policy (which will basically scrape our HD clean). For our team this means about a week of re-configuring, installing, and tweaking our desktops until we are back to work capacity - anyone who has to re-install a development machine probably knows what I'm talking about. So, I guess my question is if there's any way to perform full disk encryption on a linux (ubuntu = 9.04) system without having to re-install EVERYTHING [sigh]. IT guy said there isn't any - please prove him wrong. thanks :)

  • Verify p2p node

    - by mazzzzz
    Hey guys, I have been working on a p2p namespace for some of my programs. I created a system to encrypt/decrypt the packets send/received with the class. I was using the basic public private key system: 1) encrypt the data with Symmetric encryption 2) encrypt the symmetric key with RSA. Then do the opposite when you decrypted.. I was wondering though, how would you verify if the packet was coming from where it said it was. I was going to use a basic certificate system (where you encrypt with your private RSA key, then they decrypt it with your public key), but I don't know how to do this with C#. I am using the RSACryptoServiceProvider class. Does anyone know how do this? Thanks, Max
