WebOct 13, 2024 · There are four basic types of encryption keys: symmetric, asymmetric, public and private. Symmetric encryption: In symmetric-key cryptography, a single encryption key is used for both encryption and decryption of data. This encryption is used to protect data and is a fast algorithm. Asymmetric encryption: In asymmetric keys, a pair of keys are ... WebDec 14, 2015 · What is cryptography in ISO 27001, and what do cryptographic controls refer to? In ISO 27001, use of cryptography refer to a set of security practices to be used with the objective to ensure proper and effective use of cryptography to protect information, according to perceived risks, either when it is at rest or during communication.
