This is in response to an earlier item which asked a couple of questions about the DES. Question: .... they say that DES is fast enough such that an 8-bit micro can perform it in 100 milliseconds. My question is 100 msec per what? Miles Smid (phone 301-921-3427) tells me: "They probably mean that it takes 100 milliseconds to encrypt one 64-bit block of data." Question: ....does anyone know of a C implementation ..... Miles gave me a listing (contact him for a copy) which is titled:- "This program implements the Federal Information Processing Data Encryption Standard (FIPS PUB 46 - 1977 January 15).
