mcrypt_enc_get_algorithms_name — Returns the name of the opened algorithm
Esta função tornou-se DEFASADA a partir do PHP 7.1.0 e foi REMOVIDA a partir do PHP 7.2.0. O uso desta função é fortemente desencorajado.
This function returns the name of the algorithm.
tdThe encryption descriptor.
Returns the name of the opened algorithm as a string.
Exemplo #1 mcrypt_enc_get_algorithms_name() example
<?php
$td = mcrypt_module_open(MCRYPT_CAST_256, '', MCRYPT_MODE_CFB, '');
echo mcrypt_enc_get_algorithms_name($td). "\n";
$td = mcrypt_module_open('cast-256', '', MCRYPT_MODE_CFB, '');
echo mcrypt_enc_get_algorithms_name($td). "\n";
?>O exemplo acima produzirá:
CAST-256 CAST-256
