hash is used to obsfucate passphrase for conventional encryption, draft-ietf-openpgp-rfc2440bis-02.txt says: If the hash size is less than the key size, multiple instances of the hash context are created -- enough to produce the required key data. These instances are preloaded with 0, 1, 2, ... octets of zeros (that is to say, the first instance has no preloading, the second gets preloaded with 1 octet of zero, the third is preloaded with two octets of zeros, and so forth). == <EOF> == Disastry http://i.am/disastry/ http://disastry.dhs.org/pgp <--PGP plugins for Netscape and MDaemon ^----GPG for Win32 (supports loadable modules & IDEA) ^----PGP 2.6.3ia-multi (supports IDEA,CAST5,BLOWFISH,AES128,MD5,SHA1) -----BEGIN PGP SIGNATURE----- Version: Netscape PGP half-Plugin 0.14 by Disastry / PGPsdk v1.7.1 iQA/AwUBOp3bnDBaTVEuJQxkEQIhlwCfTalwnjoR3KnsYTDyYZGRsthOKHIAnA8m d8PluDBMKgooRcsmphmsT70f =iBA/ -----END PGP SIGNATURE-----
