PHP AES CBC模式PKCS7 128位加密
加密:
$key = ‘1234567812345678‘; $iv = ‘1234567890123456‘; $message = ‘123456‘; $blocksize = mcrypt_get_block_size(MCRYPT_RIJNDAEL_128, MCRYPT_MODE_CBC); $len = strlen($message); //取得字符串长度 $pad = $blocksize - ($len % $blocksize); //取得补码的长度 $message .= str_repeat(chr($pad), $pad); //用ASCII码为补码长度的字符, 补足最后一段 $xcrypt = mcrypt_encrypt(MCRYPT_RIJNDAEL_128, $key, $message, MCRYPT_MODE_CBC, $iv);
