It is now called ANSI X9.31 Appendix A.2.4 http://csrc.nist.gov/CryptoToolkit/tkrng.html and yes, there is NIST-Recommended Random Number Generator Based on ANSI X9.31 Appendix A.2.4 Using the 3-Key Triple DES and AES Algorithms http://csrc.nist.gov/cryptval/rng/931rngext.pdf Btw, anybody was lucky enough to cache the draft of X9.82 which was posted on the NIST site some time ago? -- Regards, ASK --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to [EMAIL PROTECTED]
