SHA-512 library for PHP

I am searching for any crypto library that provides SHA-512 hash. Googling around I found some but SHA-512 is absent.

Please suggest.

If you are using PHP >= 5.3, the function openssl_digest should do the trick :

echo openssl_digest('glop', 'sha512');

gives me this output (splitted in two lines to get better readibility) :

416b1861951170e1f6eb6543b0dd3d4f1994ce8da7cd82061513d3ddd1dd81111
f4ada5caf6421f1d17425c6f29bdb4a95cf84df9eda4164f5a762acbb490a68

(And you can use openssl_get_md_methods to get the list of available digest methods)


And with PHP 5.1 or 5.2, you have the hash function :

echo hash('sha512', 'glop');

gives me the same output (splitted, too) :

416b1861951170e1f6eb6543b0dd3d4f1994ce8da7cd82061513d3ddd1dd81111
f4ada5caf6421f1d17425c6f29bdb4a95cf84df9eda4164f5a762acbb490a68

And, here, to know the list of available digest methods, you can use hash_algos
