| Calculating Pi: Investigates and implements algorithms which may yield to distributed computation of the mathematical constant Pi. |
| distributed.net: A distributed computing project currently trying to take the RSA challenge of RC5-64, and also working on OGR-24 and 25 (Optimal Golomb Rulers). Previous projects included CSC and DES. |
| ECMNET: Project to factor numbers using the elliptic curve method. Client and server software. |
| Ellipsa - Elliptic Curve Primality Proving: Primo, a primality proving program based on the ECPP algorithm. With Primo one can check crypto-primes and prove whether or not they are actually prime. |
| Generalized Fermat Primes Search: Project provides software to search for primes of a specific form. Coordinated via email. |
| Goldbach's Conjecture and Factoring the Cryptographic Modulus: Algebraic Factoring of the Cryptography Modulus and Proof of Goldbach's Conjecture |
| Great Internet Mersenne Prime Search: Online search for Mersenne prime numbers, found largest several primes. |
| MM61: Attempt at factoring the huge Mersenne number 2^(2^61-1)-1. Software for Windows, DOS and Linux. Work reservation via email. |
| Proth Search Page: A list of prime number searches using Yves Gallot's proth.exe program, available to download. Maintained by Ray Ballinger. |
| RSA Security - Challenges: Monetary prizes for factoring certain large numbers ("RSA Numbers"), as well as breaking RSA and DES encryption schemes; announcements mailing list. |
| Search for the Largest Proth Prime: An internet group to help find the 5th largest prime number, coordinated by William Garnett. Windows/Linux software available. |
| Seventeen Or Bust: A distributed attack on the Sierpinski problem, trying to find the last remaining 17 numbers. |
| The Prime Pages: Prof. Chris Caldwell's database of virtually every large or otherwise interesting prime number known; includes the 5,000 largest known prime numbers and records for specific types. |
| The Prime Sierpinski Problem: Mathematical project to find the smallest prime Sierpinski number. |
| The Riesel Sieve Project: Distributed project to help solve the Riesel problem through the use of donated unused CPU cycles. |
