THC-Yaotp 0.1

THC-Yaotp (Yet Another One-Time Pad) is a tool that implements so called one-time pads and that is useful only to the totally paranoid geek.

Here are some key features of "THC Yaotp":

· Real random number generation by audio sampling and hashing. Generated data passes the DIEHARD RNG test suite.
· Automatic sanity check of random data using statistic values (mean, deviation, entropy) to avoid sampling EMI noise or silence.
· Key management that enforces one-time usage and irreproducible key destruction similar to secure-delete
· Obligatory message compression, checksumming, uuencoding and PGP-like ASCII output
· No whistles and bells, but a tool for the true security fanatic. (Maybe even NSA-resistent)

Example message:

BEGIN YAOTP MSG {qvT6ibeE8gQuH3iSN4knl3fDN9TlfkEkd6+74/zWoksuk27oSZIAx2d0gZeT fXZBm+BezyjYqPX+VPPiACkiyGB12E4nHW7MYm9eOlagnnPLUae/uAAAAACb} END YAOTP MSG
