im having trouble understanding pgp type encription. from what i read u send out your public key (p*q) and the persion encripting uses a session key that is used to encript the message. then that key is encripted too and sent along with the message. but that would be easy to decpyher, just divide out the public key from the product of the public key and session key and use it to decript. this sounds just as easy as a regular cypher.
this is what i read from http://www.pgpi.org/doc/pgpintro/
is it wrong?
