The cryptographic module is based on an early draft of the EXPath Cryptographic Module and provides the following functionality:
- Creation of message authentication codes (HMAC)
- Creation and validation of an XML Digital Signature
- Encryption and decryption
crypto:hmac
| Signatures | crypto:hmac($message as xs:string(), $secret-key as xs:string(), algorithm as xs:string()) as xs:string()crypto:hmac($message as xs:string(), $secret-key as xs:string(), algorithm as xs:string(), $encoding as xs:string()) as xs:string()

| Summary | Creates a message authentication code via a cryptographic hash function and a secret key. $encoding must either be hex, base64 or the empty string (default is base64) and specifies the encoding of the returned authentication code.$algorithm describes the hash algorithm which is used for encryption. Currently supported are md5, sha1, sha256, sha384, sha512.
