I need to create a database column which will store a string encrypted using Triple DES. How do I determine the length of the encrypted string column?
(Answers for algorithms other than Triple DES are also welcome.)

I am trying to mimic the results of some C code that uses the OpenSSL library using the system.security.crytography library in the .net 3.5 world, and I can't seem to get it right. I need some help... part of the issue is my understanding of crytography in general.
Here's what is supposed to happen:
I…

Are there any legal problems using external crypto libs in my iPhone application? I know that Apple has to comply to US cryptography export rules but do I as a developer have any responsibility? How does it work?

While going through RFC1321, I came across the following paragraph:
This step uses a 64-element table T[1 ... 64] constructed from the
sine function. Let T[i] denote the i-th element of the table, which
is equal to the integer part of 4294967296 times abs(sin(i)), where i
is in radians…

Should programmers who build websites/web applications understand cryptography? I have no idea how most crypographic algorithms work, and I really don't understand the differences between md5/des/aes/etc. Have any of you found any need for an in-depth understanding of cryptography?
I haven't needed…

I was told that in order to support AES256 encryption inside my Java app that I would need the JCE with Unlimited Strength Jurisdiction Policy Files.
I downloaded this from Oracle and unzipped it and I'm only seeing 2 JARs:
local_policy.jar; and
US_export_polic.jar
I just want to confirm I'm…

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…
