Cryptographic Erasure: A method of ensuring that information on a storage device is irretrievable by using a cryptographic algorithm to overwrite data with a key that is subsequently destroyed. The destruction of the key makes the data permanently inaccessible, providing an effective means of data sanitization when physical destruction of storage devices isn’t feasible or desirable.
