==== Description: ====
PENG4 ("Permutation Engine 4") is an implementation of an encryption algorithm
based on long-distance bit permutations. It is still experimental. Written in
C, 
it is suprisingly fast on modern computers. Lower performance is partially
intended because of more difficult brute force attacks. The project was
started in 1998, and in generation 4 the main objective was to avoid manual
optimizations, since surprisingly, bitpacking and access ordering have made
things worse. The algorithm and the tool is intended for top secret material,
albeit its implementation is experimental and may be faulty or too simplistic
in some point of view. Caveat utilitor!

The current algorithm can be described with CBC(X-P-X), that means, a
plaintext gets XORed, permutated and XORed again, with each round, and a CBC
block cipher mode of operation is applied.  Different sets (called
"variations") are applied
in proper order.
