This threat is a mess... What I think the problem is (in-head decoder) is you get messages encrypted with PGP software and you want to be able to decrypt/encrypt them at your school. The school doesn't allow you to install software though...

It should be possible to suply some kind of perl script with the jeys you use etc etc, and make that script parse it to some PGP programm (I don't think the perl script itself would be able to do it). AFter that the script sends you the output or something. I never heard of someone doing this, because it's pretty useless.

Is this about decrypting pgp without the software ie you want the algorythm or different software ? Or is it about circumventing your school's security stuff ? In both cases you'd try search google or suply more information...

?!?
