Re: XOR passphrase with a constant

Are you saying that prepending a constant string to the passphrase also


doesn't change the entropy or give any further advantage to an


attacker? (with common hashes like MD5 and SHA)



I have read up on the HMAC approach. The known string (or key if I used


the HMAC approach) will be known to the attacker... but there is a good


reason for it's use.
