openssl_get_md_methods - Gets available digest methods

SYNOPSIS
       array openssl_get_md_methods ([bool  $aliases = false])

DESCRIPTION
	Gets a list of available digest methods.

PARAMETERS
	      o $aliases
		- Set to TRUE if digest aliases should be included within the returned array.

RETURN VALUES
	An array of available digest methods.

EXAMPLES
       Example #1

	      openssl_get_md_methods(3) 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);

	      ?>
