SRP is a strong password authentication protocol that can be
used to set up a secure communications session when the two sides
initially share only a weak, human-memorizable password.
Sample software, including secure Telnet and FTP applications, can be
downloaded, and you can view my technical paper, which has been
published and presented in the 1998 ISOC NDSS Symposium.
A pure JavaScript implementation of large-integer math,
capable of performing useful-sized (512-bit, 1024-bit) RSA
encryption in almost any Web browser.
GRUs, or "Generalized Repunits", are numbers of the form
(bn-1)/(b-1), where b and n are both integers and
b>2 and n>2. Several of my proofs are featured in the
Prime Pages' Top-20 list of GRU primes.
My numbers appear under the prover codes CH2 and p170.
As of December 2010 I hold the record for the largest
proven GRU prime.
In 2009, I developed a prime number sieve called SGsieve
and used it to find large prime numbers of selected types,
setting some world records in the process.
These primes appear under the code
L983
on the Prime Pages.
From March 2010 to April 2012 I held the record for the largest known
Sophie Germain prime.
