autotools was Re: Encryption questions

I just started doing auto tools stuff for the last 4 months, after looking at it over a year ago and failing to understand it. The 'Goat' book does a decent job of explaining things, but an additional book that follows the 'Perl Cookbook' would be even better. One thing that the autotools highligh

AES (Advanced Encryption Standard) should do what you are looking for. It uses /dev/urandom to generate the salt, and the Rijndael algorithm and the Cipher Block Feedback method for encrypting streams of data. http://aescrypt.sourceforge.net/ FYI, Kenny Cole Tuininga wrote: > > Hi folks - I
