→crypto:decrypt
|Creates an authentication code for the specified {{Code|$data}} via a cryptographic hash function:
* {{Code|$key}} must not be empty.
* {{Code|$algorithm}} describes the hash algorithm which is used for encryption. Currently supported are {{Code|md5}}, {{Code|sha1}}, {{Code|sha256}}, {{Code|sha384}}, {{Code|sha512}}. '''Default is {{Code|md5}}'''.* {{Code|$encoding}} must either be {{Code|hex}} or {{Code|base64}}; it specifies the encoding of the returned authentication code. '''Default is {{Code|base64}}'''.
