Encryption

Cryptographic transformation of data (called "plaintext") into a form (called "cipher text") that conceals the data's original meaning to prevent it from being known or used.

The process of transforming plaintext into ciphertext.

The process of taking an unencrypted message (plaintext), applying a mathematical function to it (encryption algorithm with a key) and producing an encrypted message (ciphertext)

The process of rendering plaintext unintelligible by converting it to ciphertext that can be read only by those with the knowledge to decode the plaintext from the ciphertext. (SAA: Glossary of Archival and Records Terminology).

A data security technique used to protect information from unauthorized inspection or alteration. Information is encoded so that data appears as a meaningless string of letters and symbols during delivery or transmission. Upon receipt, the information is decoded using an encryption key.

Conversion of plaintext to ciphertext through the use of a cryptographic algorithm.

The process of changing plaintext into ciphertext for the purpose of security or privacy.

the activity of converting data or information into code
