Since the keys (depending on the algorithm - I am not an expert on that) are AFAIK calculated from random primes the reverse task, e.g. finding a public key to a given private key, sounds like a bit of reverse engineering. And I think (and if the reverse task has the same complexity I really hope it ;-)) it won't be possible. Another thought: You could generate a Keypair with a keysize small enough to remember als a password but then I think the key size is that small it won't be secure anymore. But sorry, I am not an expert on that... -- Christopher Beck Gerhart-Hauptmann-Str. 1 91058 Erlangen Tel.: 09131 / 9245437 Fax.: 09131 / 8148708 Jabber: [email protected] EPVPN: (+49 221 59619) - 5232
