Can someone tell me why these two yield totally different results ?
$key = 'abcdefgh';
echo encrypt('hello');
function encrypt($text)
{
$text = pkcs5_pad($text, mcrypt_get_block_size('rijndael-128', 'ecb'));
return trim(base64_encode(mcrypt_encrypt(MCRYPT_RIJNDAEL_128, $key, $text, MCRYPT_MODE_ECB)));
}VS.
echo encrypt('hello');
function encrypt($text)
{
$text = pkcs5_pad($text, mcrypt_get_block_size('rijndael-128', 'ecb'));
return trim(base64_encode(mcrypt_encrypt(MCRYPT_RIJNDAEL_128, 'abcdefgh', $text, MCRYPT_MODE_ECB)));
}I figured it was the same thing, but they return totally different results. However, if I pass in a constant for the same value... it yields the same result at the 2nd code snippet.
define(SALT, 'abcdefgh');
echo encrypt('hello');
function encrypt($text)
{
$text = pkcs5_pad($text, mcrypt_get_block_size('rijndael-128', 'ecb'));
return trim(base64_encode(mcrypt_encrypt(MCRYPT_RIJNDAEL_128, SALT, $text, MCRYPT_MODE_ECB)));
}
