This XQuery Module provides functions that perform different hash operations.

Conventions

All functions and errors in this module are assigned to the http://basex.org/modules/hash namespace, which is statically bound to the hash prefix.

Functions

hash:md5

Signatures hash:md5($value as xs:anyAtomicType) as xs:base64Binary
Summary Computes the MD5 hash of the given $value, which may be of type xs:string, xs:base64Binary, or xs:hexBinary.
Examples
  • string(xs:hexBinary(hash:md5("BaseX"))) returns 0D65185C9E296311C0A2200179E479A2.
  • string(hash:md5(xs:base64Binary(""))) returns 1B2M2Y8AsgTpgAmY7PhCfg==.

hash:sha1

Signatures hash:sha1($value as xs:anyAtomicType) as xs:base64Binary
Summary Computes the SHA-1 hash of the given $value, which may be of type xs:string, xs:base64Binary, or xs:hexBinary.
Examples
  • string(xs:hexBinary(hash:sha1("BaseX"))) returns 3AD5958F0F27D5AFFDCA2957560F121D0597A4ED.
  • string(hash:sha1(xs:base64Binary(""))) returns 2jmj7l5rSw0yVb/vlWAYkK/YBwk=.

hash:sha256

Signatures hash:sha256($value as xs:anyAtomicType) as xs:base64Binary
Summary Computes the SHA-256 hash of the given $value, which may be of type xs:string, xs:base64Binary, or xs:hexBinary.
Examples
  • string(xs:hexBinary(hash:sha256("BaseX"))) returns 15D570763DEB75D728BB69643392873B835CCCC94A2F1E881909DA47662821A3.
  • string(hash:sha256(xs:base64Binary(""))) returns 47DEQpj8HBSa+/TImW+5JCeuQeRkm5NMpJWZG3hSuFU=.

hash:hash

Signatures hash:hash($value as xs:anyAtomicType, $algorithm as xs:string) as xs:base64Binary
Summary Computes the hash of the given $value, using the specified $algorithm. The specified values may be of type xs:string, xs:base64Binary, or xs:hexBinary.
The following three algorithms are supported: MD5, SHA-1, and SHA-256.
Errors algorithm: the specified hashing algorithm is unknown.
Examples
  • string(xs:hexBinary(hash:hash("", "MD5"))) returns D41D8CD98F00B204E9800998ECF8427E.
  • string(hash:hash("", "")) raises an error, because no algorithm was specified.

Errors

Code Description
algorithm The specified hash algorithm is unknown.

Changelog

Version 9.0
  • Updated: error codes updated; errors now use the module namespace

The module was introduced with Version 7.3.
