内容：abcd
key:1234567890123456
加密后base64：t7ut2nq1afvr9unja0wkwa==
function apidatadecrypt($data, $key='') {
$data = base64_decode($data);
$pad = 16 - (strlen($data) % 16);
$paddata = $data . str_repeat(chr($pad), $pad);
return mcrypt_decrypt(mcrypt_rijndael_128, $key,$paddata, mcrypt_mode_ecb);
}
}
直接附上解决方案吧
$key = '1234567890123456';
$content = 't7ut2nq1afvr9unja0wkwa==';
$desstr = decryptstring($content,$key);
echo($desstr);
function decryptstring($str,$key) {
$str = base64_decode($str);
$str = mcrypt_decrypt(mcrypt_rijndael_128, $key, $str, mcrypt_mode_ecb);
$block = mcrypt_get_block_size('rijndael_128', 'ecb');
$pad = ord($str[($len = strlen($str)) - 1]);
$len = strlen($str);
$pad = ord($str[$len-1]);
return substr($str, 0, strlen($str) - $pad);
}
以上所述就是本文的全部内容了，希望大家能够喜欢。
