-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 GPG and PGP use a hash on the symmetric key you enter, because the hash contains more entropy: It is always 128 bits of enhanced randomness, so the best reason for hashing your keystrokes is because people are not always very creative with their pass-phrases. Phil Zimmerman coined that term, because even after he did the work of hashing pass-phrases, he wasn't convinced that people would always come up with sixteen letterz for their security, AND it was hard to prove that hashing a key was effective against short or sloppy symmetric keys. I imajin that you want to use a key with all zeros to test the symmetric encryption method. Well...your final analysis should include the effect of hashing your zeros. _______ http://ecn.ab.ca/~brewhaha/ BrewJay's Babble Bin -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.2 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQCVAwUBTgMEjR47apzXdID2AQJIBwP+K/z8fgdmspRcvWNvlepNigk8MIbv6GDd o+GqWs8DTQ2WvjA+4pdh992SfpVqrXOAhyAezQ9KrJ/CmUCX3cri5Rv3LkHUN3Sw dpR6K1xMbbettoJx9Lo9fCmm2iOgWEQyHd4irG9Xxs+AsOXuIVe2sPOxi5ayrLc+ 7YuQrdxgbxg= =g9wJ -----END PGP SIGNATURE-----
