Are there other efforts to find RSA's Secret DES Key?

DESCHALL Project Frequently Asked Questions
Yes. After some other efforts folded, there are three efforts that are major contenders for finding the key. These are... It's noteworthy that we've got the fastest key search rate by far. Despite the fact that we seem to have fewer clients than another, the ones we have are extremely fast. As a result, we've nearly moved into first place for amount of keyspace searched, and we have been holding on to first place for keyspace search rate for quite some time. See similar questions...

The RSA private key file is a digital file that you can use to decrypt messages sent to you. It has a public component which you distribute (via your Certificate file) which allows people to encrypt those messages to you. A Certificate Signing Request (CSR) is a digital file which contains your public key and your name. You send the CSR to a Certifying Authority (CA) to be converted into a real Certificate.
