Cerulean Studios, creators of the Trillian instant messaging client,
has provided financial assistance to the project.

Barry Kavanagh of AEP Systems Ltd kindly provided an AEP2000 crypto card and
drivers, enabling the creation of Botan's AEP engine module.

In addition, the following people have unknowingly contributed help
via public domain code which has been repurposed into the library:

  Dean Gaudet wrote the SSE2 implementation of SHA-1

  The implementation of DES is based off a public domain implementation by Phil
  Karn from 1994 (he, in turn, credits Richard Outerbridge and Jim Gillogly).

  Rijndael and Square are based on the reference implementations written by
  the inventors, Joan Daemen and Vincent Rijmen.

  The Serpent S-boxes used were discovered by Dag Arne Osvik and detailed in
  his paper "Speeding Up Serpent".

  Matthew Skala's public domain twofish.c (as given in GnuPG 0.9.8) provided
  the basis for my Twofish code (particularly the key schedule).

  Some of the hash functions (MD5, SHA-1, etc) use an optimized implementation
  of one of the boolean functions, which was discovered by Colin Plumb.

  The design of Randpool takes some of its design principles from those
  suggested by Eric A. Young in his SSLeay documentation, Peter Gutmann's paper
  "Software Generation of Practically Strong Random Numbers", and the paper
  "Cryptanalytic Attacks on Pseudorandom Number Generators", by Kelsey,
  Schneier, Wagner, and Hall.
