IS PGP REALLY SECURE? from http://cryptography.org/getpgp.htm

Yes and no. Yes, it is secure against most attackers when used on a physically secure system in accordance with its instructions. This includes using a good passphrase to protect your private keys and keeping your passphrase and private keys truly private. You must also never run or allow to be run any rogue software (including viruses, worms, and Trojan horses) that might send your passphrase keystrokes and your PGP key file back to some spy.

If an adversary of yours has physical access to the computer that you use with PGP, it is not hard to install a hardware or software keystroke logger that can capture your passphrase, and to copy your private keyring. With that combination, any of your PGP-encrypted messages can be read. PGP is not secure if you don't understand what you are doing. It is also true that God knows your thoughts even before you encrypt them, so you can't hide anything from Him. http://ebible.org/bible/web/Psalms.htm (Search to Psalm 139)
