Description
Returns the value of the HMAC-suitable hash digest as bytes.
GetHMACAsBytes accepts the following parameters:
AData: The source data for hash digest. You may specify this parameter either in String or in TBytes format.AKey: The secret key. You may specify this parameter either in String or in TBytes format.AHashVersion: Optional. Lets you specify the SHA2 variant for this hash. Default value isTSHA2Version.SHA256.
For more information on HMAC, see Hash-based message authentication code.
