     This is a collection of SECURE encryption algorithms (BLOWFISH, TWOFISH, SKIPJACK, TEA, GOST, RC4 and DES). This post contains highly optimized code, if a similar post already exist here on PSC this one is at least a couple of 1000x faster!! This is not like everybody else's "unbreakable" code, these are standardized encryption algorithms where the only possible way to crack it is by brute-force. DES is probably the least secure one (it took 22 hours for a supercomputer + 100,000 computers to crack it (distributed.net)). And that's the least secure one. ;)

Note: Due to the size or complexity of this submission, the author has submitted it as a .zip file to shorten your download time. Afterdownloading it, you will need a program like Winzip to decompress it.Virus note:All files are scanned once-a-day by Planet Source Code for viruses, but new viruses come out every day, so no prevention program can catch 100% of them. For your own safety, please:
  1. Re-scan downloaded files using your personal virus checker before using it.
  2. NEVER, EVER run compiled files (.exe's, .ocx's, .dll's etc.)--only run source code.
  3. Scan the source code with Minnow's Project Scanner

If you don't have a virus scanner, you can get one at many places on the net including:McAfee.com

Hi Fredrik Qvarfort,

Thank you for the useful post.
Is there any .NET version of this code is available for this?

'Thanks and Regards
