hash_hmac_algos

(PHP 7 >= 7.2.0)

hash_hmac_algos — Return a list of registered hashing algorithms suitable for hash_hmac

Description

hash_hmac_algos ( ) : array

Return Values

Returns a numerically indexed array containing the list of supported hashing algorithms suitable for hash_hmac().

Examples

Example #1 hash_hmac_algos() example

<?php
print_r(hash_hmac_algos());

The above example will output something similar to:

Array
(
    [0] => md2
    [1] => md4
    [2] => md5
    [3] => sha1
    [4] => sha224
    [5] => sha256
    [6] => sha384
    [7] => sha512/224
    [8] => sha512/256
    [9] => sha512
    [10] => sha3-224
    [11] => sha3-256
    [12] => sha3-384
    [13] => sha3-512
    [14] => ripemd128
    [15] => ripemd160
    [16] => ripemd256
    [17] => ripemd320
    [18] => whirlpool
    [19] => tiger128,3
    [20] => tiger160,3
    [21] => tiger192,3
    [22] => tiger128,4

    [30] => haval160,3
    [31] => haval192,3
    [32] => haval224,3
    [33] => haval256,3
    [34] => haval128,4
    [35] => haval160,4
    [36] => haval192,4
    [37] => haval224,4
    [38] => haval256,4
    [39] => haval128,5
    [40] => haval160,5
    [41] => haval192,5
    [42] => haval224,5
    [43] => haval256,5
)

Notes

Note:

Before PHP 7.2.0 the only means to get a list of supported hash algorithms has been to call hash_algos() which also returns hash algorithms that are not suitable for hash_hmac().
