openssl_get_cipher_methods

OPENSSL_GET_CIPHER_METHODS(3)						 1					     OPENSSL_GET_CIPHER_METHODS(3)

openssl_get_cipher_methods - Gets available cipher methods

SYNOPSIS

       array openssl_get_cipher_methods ([bool	$aliases = false])

DESCRIPTION

	Gets a list of available cipher methods.

PARAMETERS

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

RETURN VALUES

	An array of available cipher methods.

EXAMPLES

       Example #1

	      openssl_get_cipher_methods(3) example

	       Shows how the available ciphers might look, and also which aliases might be available.

	      <?php
	      $ciphers		   = openssl_get_cipher_methods();
	      $ciphers_and_aliases = openssl_get_cipher_methods(true);
	      $cipher_aliases	   = array_diff($ciphers_and_aliases, $ciphers);

	      print_r($ciphers);

	      print_r($cipher_aliases);

	      ?>

	      The above example will output something similar to:
