| '''Summary'''
|Encrypts data with the given specified key:* {{Code|$inputdata}}, which can must be a string or binary item:<br/>.
* {{Code|$encryption}} must be {{Code|symmetric}}.
* {{Code|$key}} is the secret key which is used for both encryption and decryption of input data. It can be a string or binary item. Its length is fixed and depends on the chosen algorithm: {{Code|8 bytes for DES}}, {{Code|16 bytes for AES}}.
