encryption
Any procedure used in {cryptography}
to convert {plaintext} into {ciphertext} (encrypted message)
in order to prevent any but the intended recipient from
reading that data.
Schematically, there are two classes of encryption primitives:
{public-key cryptography} and {private-key cryptography}; they
are generally used complementarily.
Public-key encryption algorithms include {RSA};
private-key algorithms include the obsolescent {Data Encryption
Standard}, the {Advanced Encryption Standard}, as well as
{RC4}.
The {Unix} command {crypt} performs a weak form of encryption.
Stronger encryption programs include {Pretty Good Privacy} and
the {GNU Privacy Guard}.
Other closely related aspects of {cryptograph} include
{message digests}.
