   Revised: 23-Sep-99 [Reliable v1.0.2]

Are the OpenPGP encrypted emails not padded?

mixmaster
---------

Code in sourceforge [^mixmaster origin] is not in CVS system.

Uses RSA (and DSA?) for encryption and PKCS#1 for padding.

Several repositories with some updates

One of the first versions, 2.9beta32 says:

   It supports OpenPGP encryption (compatible with PGP 2, PGP 5 and
   GnuPG).

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

   provide a Mixmaster-like protocol with support for larger RSA keys
   (up to 4096 bits), replacement Hash (SHA2) and Symmetric Ciphers
   (AES). Instead of using SMTP for inter-Remailer traffic, Mimix uses
   HTTP.
