This is getting slightly offtopic: Gary is pointing to the EFF DES cracker, more info can be found at http://www.eff.org/Privacy/Crypto_misc/DESCracker/HTML/19980716_eff_des_faq.html It will cost you slightly more that $2.000, but it is clear that DES is not a protocol to rely on if you wish complete security. (Small note: 64 bits encryption is actually 56-bit DES, since 12.5% of the bits are used for error detection). Regards, Johannes
