Encryption Essentials: A PGP Quick-Start Guide
PGP puts your email or files in a digital envelope that only the intended recipient with a copy of PGP can decipher. Anybody else sees a random-looking sequence of ASCII characters.

Unfortunately, most of those products are susceptible to "password cracker" programs readily available at various Internet sites either in freeware form, often aimed at the black-hat community, or as commercial ware marketed to corporate help desks who help their users figure out the passwords they forgot.
