This XQuery Module provides functions that perform different hash operations.
Contents
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
hash:md5
Signatures | hash:md5($value as xs:anyAtomicType) as xs:base64Binary |
Summary | Computes the MD5 hash of the given $value , which may be of type xs:string, xs:base64Binary, or xs:hexBinary.
|
Examples |
|
hash:sha1
Signatures | hash:sha1($value as xs:anyAtomicType) as xs:base64Binary |
Summary | Computes the SHA-1 hash of the given $value , which may be of type xs:string, xs:base64Binary, or xs:hexBinary.
|
Examples |
|
hash:sha256
Signatures | hash:sha256($value as xs:anyAtomicType) as xs:base64Binary |
Summary | Computes the SHA-256 hash of the given $value , which may be of type xs:string, xs:base64Binary, or xs:hexBinary.
|
Examples |
|
hash:hash
Signatures | hash:hash($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 algorihms are supported: MD5 , SHA-1 , and SHA-256 .
