Crypt::OTP - Perl implementation of the One Time Pad (hence, OTP) encryption method. River stage one • 1 direct dependent • 1 total dependent

The One Time Pad encryption method is very simple, and impossible to crack without the actual pad file against which the to-be-encrypted message is XOR'ed. Encryption and decryption are performed using excactly the same method, and the message will d...

Crypt::RC5 - Perl implementation of the RC5 encryption algorithm. River stage zero No dependents

RC5 is a fast block cipher designed by Ronald Rivest for RSA Data Security (now RSA Security) in 1994. It is a parameterized algorithm with a variable block size, a variable key size, and a variable number of rounds. This particular implementation is...

Crypt::GOST_PP - Pure Perl implementation of the GOST encryption algorithm River stage one • 1 direct dependent • 1 total dependent

GOST is a 64-bit symmectric block cipher with a 256-bit key, from the former Soviet Union. It is important to note that there are (or have been) several other GOST encryption modules for perl. This version is in no way intended to supersede any other...

Acme::Playwright - Simple text obfuscation in the form of a play. River stage one • 1 direct dependent • 1 total dependent

To be honest, I did this mostly for the comedy value. I was toying with the idea of making a real steganography module, and the next thing I knew, I was writing Playwright instead. It does offer a degree of security (albeit not a terribly high degree...
