Encryption - Password Sofware
(OP)
Does anyone know of an Encryption - Password sofware package that provides HIGH security without significantly increasing the file size ?
Usage is to prevent 'third party' cracking when files are transmitted via a shared email-server. Adobe *.pdf and (obviously) Microsoft Office files are being accessed by the 'sever-spies'.

PS Re-reading my post I see I have to learn to spell "sofTware".

If you truly need HIGH security, then the file size consideration should be waived. Much of the strength of encryption comes at a cost of additional storage space. Without increasing the file size at all (or using compression), the best you can get is a simple substitution cypher, every A is changed to C, every D is changed to X, and so on. Obviously this sort of thing can be broken very easily.
PGP is good for another reason -- it's open-source. If you want to, you can verify that it is secure by checking the code. With closed source software from commercial vendors, you are forced to rely on their promises.

One thing you should know is that aysymmetric encryption such as used on PGP is orders of magnitude slower thatn symmetric key, which is why PGP is usually used to send/receive text, or exchange keys for a symmetric algorithm. Both methods are considered to be generally very secure, with the weak point usually being the user or the computer the data was encrypted on. A brute force attack on either (assuming a good key was used (i.e. randomly generated)) would be a waste of time.
