Which hash algorithms are already embedded in PHP?

Recently I was looking for hash algorithms that were not known md5, sha1 and sha2, and that generate smaller hashs than those cited.

That’s when I found myself thinking, how can I know which hash algorithms are available for my use, in PHP?

PHP already comes with a range of hash algorithms available for use, including it has a specific function to show which algorithms are available, the hash_algos().

When rotating this function, it will return a array with all available methods, example:

print_r(hash_algos());

The above code would print the following:

Array
(
    [0] => md4
    [1] => md5
    [2] => sha1
    [3] => sha256
    [4] => sha384
    [5] => sha512
    [6] => ripemd128
    [7] => ripemd160
    [8] => whirlpool
    // ...

To use a specific algorithm you can use the function hash(), example:

echo hash("crc32b", "minha-string");
// imprime: 5373ff38
