encryption[en′krip·shən] (computer science) The coding of a clear text message by a transmitting unit so as to prevent unauthorized eavesdropping along the transmission line; the receiving unit uses the same algorithm as the transmitting unit to decode the incoming message. encryption (algorithm, cryptography)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 Encryption Standard, 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.encryptionThe reversible transformation of data from the original (plaintext) to a difficult-to-interpret format (ciphertext) as a mechanism for protecting its confidentiality, integrity and sometimes its authenticity. Encryption uses an encryption algorithm and one or more encryption keys. See encryption algorithm and cryptography.encryption
en·cryp·tion (en-krip'shŭn) The scrambling of electronic information being stored and sent so that if someone wrongly receives such information it will not be readable. encryption
EncryptionThe coding of sensitive information for transfer online or otherwise electronically. One may encrypt data to prevent anyone other than the intended recipient from accessing it. For example, if one buys a product online and enters credit card information into an electronic form, that information is usually encrypted so hackers and potential identity thieves cannot use it for illicit purposes.encryption The manipulation of data to prevent accurate interpretation by all but those for whom the data is intended. Financial institutions use encryption to increase the security of data transmitted via the Internet.See ENCR
