Conventions
All functions in this module are assigned to the http://basex.org/modules/hash namespace, which is statically bound to the hash prefix.
All errors are assigned to the http://basex.org/errors namespace, which is statically bound to the bxerr prefix.
Functions
util:md5
| Signatures | util:md5($value as item()) as xs:hexBinary |
| Summary | Computes the MD5 hash of the given $value, which may be a string or a binary item (xs:base64Binary, xs:hexBinary).
|
| Examples |
|
util:sha1
| Signatures | util:sha1($value as item()) as xs:hexBinary |
| Summary | Computes the SHA-1 hash of the given $value, which may be a string or a binary item (xs:base64Binary, xs:hexBinary).
|
| Examples |
|
util:sha256
| Signatures | util:sha256($value as item()) as xs:hexBinary |

|
| Examples |
|
util:hash
