Hello, I have a little question about some math algorithms. People have talked in alt.security.pgp about the Miller Test and the Miller-Rabin Test. I am getting ready to improve PGP's testing of potential prime numbers and have been looking for a good algorithm. After reading some in Knuth Volume 2, I have come across Algorithm P on page 379. Is this algorithm in fact the Miller-Rabin Test ??? Thanks, Tom Rollins <trollins@debbie.telos.com>

As it turns out, Miller-Rabin and a modified Lucas test has already been coded up for the next release of PGP. >After reading some in Knuth Volume 2, I have come across >Algorithm P on page 379. Is this algorithm in fact the >Miller-Rabin Test ??? I don't have a copy of this handy, or I'd tell you. Basically, Miller-Rabin is similar Fermat except you continue testing and divide by two.
