The common RSA scheme will work by using the private key normally used for decryption to encrypt the message, then the public key will decrypt. Make sense? However, I agree with a later posting: what's the point? Verification? Why didn't you say so? On the practical side, surely somebody has written a public domain RSA system. Right? Somebody speak up! If not, then there's a definate shortage in the PD Unix software.... If nobody posts anything in the next week, I'll come up with something. -- Steve Tate UUCP: ..!{ihnp4,decvax}!duke!srt CSNET: srt@duke ARPA: srt%duke@csnet-relay
