I recently met Michael Coles and Rodeney Landrum the author of one of the kind book Expert SQL Server 2008 Encryption at SQLPASS in Seattle.
During the conversation we ended up how Microsoft is evolving encryption technology. The same discussion lead to talking about history of encryption tools in…

So, I've got an app at work that encrypts a string using ColdFusion. ColdFusion's bulit-in encryption helpers make it pretty simple:
encrypt('string_to_encrypt','key','AES','HEX')
What I'm trying to do is use Ruby to create the same encrypted string as this ColdFusion script is creating. Unfortunately…

I am making a licensing system when clients ask my server for a license and I send them a license if they are permitted to have one.
On my current system I encrypt the license using a single private key and have the public key embedded into the client application that they use to decrypt the license…

I need to generate and validate product keys and have been thinking about using a public/private key system.
I generate our product keys based on
a client name (which could be a variable length string)
a 6 digit serial number.
It would be good if the product key would be of a manageable length…

I have an idea for encryption that I could program fairly easily to encrypt some local text file.
Given that my approach is novel, and does not use any of the industry standard encryption techniques, would I be able to test the strength of my encryption using 'cracker' apps or suchlike?
Or do all…

Hi friends,
I am trying to write a small application using bouncycastle algorithm, from the http://tinyurl.com/ylclavn (BouncyCastleProvider.java) it says we have to import and add the provider during runtime by the following code
import org.bouncycastle.jce.provider.BouncyCastleProvider;
Security…

Hi, I'm trying to write an c#.net app to encrypt files using my private key (in ascii format) and any other public key (also in ascii format). The BouncyCastle library looks like the correct thing to use, but I cannot find documentation for C#. Could anyone please give me an example of how to use…

Hi,
through the bouncycastle wiki page I was able to understand how to create a X.509 root certificate and a certification request, but I do not quite understand how to proceed concept- and programming wise after that.
Lets assume party A does a cert request and gets his client certificate from…

can anyone give me an example for using GCM and/or CCM modes with AES in BouncyCastle?
My code is this:
SecretKeySpec key = new SecretKeySpec(keyBytes, "AES");
IvParameterSpec ivSpec = new IvParameterSpec(ivBytes);
Cipher cipher = Cipher.getInstance("AES/AEAD/PKCS5Padding"…
