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:
