Any procedure used in cryptographyto convert plaintext into ciphertext (encrypted message)in order to prevent any but the intended recipient fromreading that data.Schematically, there are two classes of encryption primitives:public-key cryptography and private-key cryptography; theyare generally used complementarily.Public-key encryption algorithms include RSA;private-key algorithms include the obsolescent Data EncryptionStandard, the Advanced Encryption Standard, as well asRC4.The Unix command crypt performs a weak form of encryption.Stronger encryption programs include Pretty Good Privacy andthe GNU Privacy Guard.Other closely related aspects of cryptograph includemessage digests.
