This module contains XQuery functions to perform cryptographic operations in XQuery. 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
This module is introduced with Version 7.0 of BaseX.
Contents
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 .
|
Errors | FOCX0013 is raised if the specified hashing algorithm is not supported. FOCX0014 is raised if the specified encoding method is not supported. |
