(PHP 5 >= 5.1.2, PECL hash >= 1.1)
hash_algos — Return a list of registered hashing algorithms
Description
array hash_algos
( void
)
Return Values
Returns a numerically indexed array containing the list of supported hashing algorithms.
Examples
Example #1 hash_algos() example
As of PHP 5.1.2, hash_algos() will return the following list of algorithm names.
<?php
print_r(hash_algos());
?>
The above example will output:
Array

[0] => md4
[1] => md5
[2] => sha1
[3] => sha256
[4] => sha384
[5] => sha512
[6] => ripemd128
[7] => ripemd160
[8] => whirlpool
[9] => tiger128,3
[10] => tiger160,3
[11] => tiger192,3
[12] => tiger128,4
[13] => tiger160,4
[14] => tiger192,4
