Return a list of registered hashing algorithms
array hash_algos ( void )
Returns:
Returns a numerically indexed array containing the list of supported hashing algorithms.
Changelog:
5.6.0
Support for gost-crypto was added. This implements the GOST hash function using the CryptoPro S-box tables as specified by » RFC 4357, section 11.2.
5.4.0
Support for joaat, fnv132 and fnv164 was added. Support for Salsa10 and Salsa20 was removed.
5.3.0
Support for md2, ripemd256, ripemd320, salsa10, salsa20, snefru256 and sha224 was added
Examples:
hash_algos() example
As of PHP 5.6.0, hash_algos() will return the following list of algorithm names.
<?php print_r(hash_algos()); ?>
The above example will output something similar to:
