== Why PrimeGrid? == | == Why PrimeGrid? == | ||
On 12 June 2005, at approximately 14:00 UTC, Message@Home (now PrimeGrid) opened account creation to 50 users. It was being run on Rytis’ home laptop. Message@Home was developed as a test project for PerlBOINC, an attempt to implement the BOINC server system in the Perl programming language in order to bring BOINC server software to Windows. | |||
The first project was Message7, and it attempted by “brute-force” to recover a message encoded with the md5 algorithm. In August, the RSA 640 Factoring Challenge application replaced the Message7 application and in November the project was renamed PrimeGrid after a short public contest.[https://primegrid.fandom.com/wiki/History_of_PrimeGrid] | |||
== Goal == | == Goal == | ||
PrimeGrid's primary goal is to advance mathematics by enabling everyday computer users to contribute their system's processing power towards prime finding. By simply downloading and installing BOINC and attaching to the PrimeGrid project, participants can choose from a variety of prime forms to search. With a little patience, you may find a large or even record breaking prime and enter into Chris Caldwell's The Largest Known Primes Database with a multi-million digit prime! | |||
PrimeGrid's secondary goal is to provide relevant educational materials about primes. Additionally, we wish to contribute to the field of mathematics. | |||
Lastly, primes play a central role in the cryptographic systems which are used for computer security. Through the study of prime numbers it can be shown how much processing is required to crack an encryption code and thus to determine whether current security schemes are sufficiently secure. | |||
