Hello Davie. As a matter of fact, I work in the EFT business and deal with crypto keys daily. I can tell you that there are many regulations and policies that banks, credit unions, and processing companies must follow concerning crypto including the handling of clear keys, encryption keys (A.K.A. master keys in the biz), and the encryption/decryption processors.
I can tell you that what we do is based on several FIPS pubs (www.itl.nist.gov/fipspubs/). This includes both DES and 3DES (pub 46-3), and we're looking at AES (pub 197). Your program has to comply with these pubs, as well as pub 140-2 to cover its own security. And you'll want to look at pubs 74 and 81 to understand the variants applied to DES and 3DES to further secure an otherwise publicly available algorithm. Best of luck, L -----Original Message----- From: davie elliott [mailto:[EMAIL PROTECTED]] Sent: Friday, March 22, 2002 4:32 PM To: [EMAIL PROTECTED] Subject: cryptography I was wondering if I could get a little information please. I have to do a huge program at the end of my course and I was thinking about making a bank program. I would like to make it as realistic as possible, so I have had a look at some encryption algorithms. However, one of my lecturers has told me that there is more to encrytion than just one algorithm. I was wondering if anyone can give me a few sites or point me in the right direction so that I can reaserch into encrytpion deeper. Thank you P.S. someone posted a couple of sites a while back on cryptography, but I had to format before I got chance to view them. I would e greatful if that person could repost them. __________________________________________________ Do You Yahoo!?
