[Asterisk-Users] GPL thoughts

[AST 386sx]

Ron,

You hit the best application of GPL.  Encryption program can be completely 
open source without losing the privacy of the encrypted data.  You can 
either use one way encryption such as any UNIX password system or 
public-private key pair as PGP.  They are all open source, but it is 
difficult to decrypt the information out of the file as long as you do not 
issue the key to the other party.
