Crypto Zip File
Unlike conventional crypto programs, which offer a compromise between
security and performance, CCRP does not compromise security with the
usual mathematical randomizations. CCRP's randomization is created by
multiple shufflings of a lookup table (like a lottery tumbler's
contents), where each shuffle is specified by the user's random input
value for that shuffle layer.
This program has withstood several chosen plaintext attacks with a 10
thousand dollar (circa 2004) award.
