PREFIXCODING, Version 2.0, available at:
http://s13.zetaboards.com/Crypto/topic/7164646/1 /, is an
encryption scheme (with authentication) with pseudo-random
prefix codes substitution and pseudo-random transposition.
It has two kinds of processing dynamics: re-generation of
the code table and injection of dummy bits. There is a
shuffling of the plaintext string as pre-processing and a
shuffling of the byte sequence resulting from prefix encoding
as post-processing.

PROVABLEPRIME Version 1.1.1 has been released
http://s13.zetaboards.com/Crypto/topic/7234475/1 /.
It is a minor new version, containing modifications of code lines
of Example 3 such that it can encrypt either a plaintext string or
a byte sequence.
