     The implementation of the AES cipher (also known as rijndael) is
     written by Rafael Sevilla. Assembler for x86 by Rafael Sevilla and
     Niels Möller, Sparc assembler by Niels Möller. Released under the
     LGPL.

     written by Niels Möller. Released under the LGPL.

ARCTWO
     The implementation of the ARCTWO (also known as RC2) cipher is
     written by Nikos Mavroyanopoulos and modified by Werner Koch and
     Simon Josefsson. Released under the LGPL.

BLOWFISH
     The implementation of the BLOWFISH cipher is written by Werner
     Koch, copyright owned by the Free Software Foundation. Also hacked

     some by Andreas Sigfridsson and Niels Möller. Python Cryptography
     Toolkit license (essentially public domain).

MD4
     This is almost the same code as for MD5 below, with modifications
     by Marcus Comstedt. Released into the public domain.

MD5
     The implementation of the MD5 message digest is written by Colin
     Plumb.  It has been hacked some more by Andrew Kuchling and Niels
