 [0x01] Introduction
  
	Welcome to the project web site of Yaotp (Yet Another One-Time Pad),
	a tool that implements so called one-time pads and that is useful
	only to the totally paranoid geek. 
	
	Beside the boring en- and decryption the core features include: 

	   - 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)

 
 [0x02] Documentation
 
	Before you start wondering about one-time pads and their practical
	impact, consult the Yaotp documentation and learn about all the
	drawbacks, the tricky key generation and the key management.  

	The Yaotp documentation also contains a quick tutorial for the
	nervous reader who doesn't want to waste free time learning
	background details.
