There's no such thing as a "key" to use MD5. MD5 is a hash algorithm, implemented with the md5 program. If you want to encrypt something that you want to be able to decrypt later, consider one of the ciphers. Do "openssl help" to get the available set of ciphers. -- Richard Levitte \ Spannvägen 38, II \ [EMAIL PROTECTED] Chairman@Stacken \ S-168 35 BROMMA \ T: +46-8-26 52 47 Redakteur@Stacken \ SWEDEN \ or +46-708-26 53 44 Procurator Odiosus Ex Infernis -- [EMAIL PROTECTED] Member of the OpenSSL development team Unsolicited commercial email is subject to an archival fee of $400.
