I heard some time that encryption and cipher are not the same thing, if so, what's the difference?

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…

For PCI-DSS compliance you have to disable weak ciphers. PCI-DSS permits a minimum cipher size of 128 bits.
However for the highest score (0 I believe) you should only accept 168 bit ciphers but you can still be compliant if you permit 128 bit ciphers.
The trouble is that when we disable all but…

I'm running a Lucid Netbook Remix on my Dell Inspiron 600m and I was not able to connect to the wireless network at the Hacker Dojo in Mountain View yesterday. There were plenty of other people on the network - MS, Mac, and Linux boxes - but my laptop would never get an ip address. I can connect to…

I am trying to use curl built with NSS (not built with OpenSSL) on Fedora 14 to connect to a webpage over https. The server to which I am connecting (example.com) uses the RC4-SHA cipher for its SSL. Whenever I try to connect to example.com, I get the NSS error SSL_ERROR_NO_CYPHER_OVERLAP. I can connect…
