Pretty Good Privacy (PGP) is a cryptographic software suite used for encrypting, decrypting, signing and verifying texts, e-mails, files, directories, and whole disk partitions. Its primary aim is to increase the security of e-mail communications. It was created by Phil Zimmermann in 1991.
PGP follows the OpenPGP standard (RFC 4880) for encrypting and decrypting data.
GNU Privacy Guard (GnuPG or GPG) is a free software replacement for the PGP cryptographic software suite. It is also compliant with RFC 4880.
Sites relating to the use of Steganography as a computer data security technique.Steganography is a technique related to cryptography where data is concealed within another file, usually an image. Stegnographic techniques can be employed in conjunction with strong encryption, further reducing the chances of discovery or disclosure.
