You have given english sentence of 12 words as passphrase. If we count about 2.5bits of information per word and hash without adding salt, it results in about 2^30 combinations. When we divide it over botnet of 1000 computers, each must try about 10^6 hashes. I guess you can calculate the rest of the anwers. -- Martin Tomasek --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to [EMAIL PROTECTED]
