Cryptographic Module

The cryptographic module is based on an early draft of the EXPath Cryptographic Module and provides the following functionality:

1. Creation of message authentication codes (HMAC)
2. Creation and validation of an XML Digital Signature
3. 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.
