openssl_get_md_methods — Gets available digest methods
Gets a list of available digest methods.
An array of available digest methods.
Example #1 openssl_get_md_methods() example
Shows how the available digests might look, and also which aliases might be available.
<?php
$digests = openssl_get_md_methods();
$digests_and_aliases = openssl_get_md_methods(true);
$digest_aliases = array_diff($digests_and_aliases, $digests);
print_r($digests);
print_r($digest_aliases);
?>The above example will output something similar to:
