We describe a distributed computing platform to carry out large scale dictionary attacks against
cryptosystems compliant to the OpenPGP standard. Moreover, we describe a simplified mechanism
to quickly test passphrases that might protect a specified private key ring. Only passphrases that
pass this test complete the (much more time consuming) full validation procedure. This approach
greatly reduces the time required to test a set of possible passphrases.
