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.
Main features:
- 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)
