AES加密例子（python和php版本）

python版本输入的加密字符必须是16的倍数，php的默认补零，所以解密的时候还需要rtrim掉零。python没有自动做这件事情，所以要自己补零。

class MyCrypt():    def __init__(self, key):        self.key = key        self.mode = AES.MODE_CBC        self.padding = '\0'?    def encrypt(self, text):        cryptor = AES.new(self.key, self.mode)        length = 16        count = text.count('')        if count < length:            add = (length - count) + 1            text += (self.padding * add)        elif count > length:            add = (length - (count % length)) + 1            text += (self.padding * add)        self.ciphertext = cryptor.encrypt(text)        return self.ciphertext?    def decrypt(self, text):        cryptor = AES.new(self.key, self.mode)        plain_text = cryptor.decrypt(text)        return plain_text.rstrip("\0")?if __name__ == '__main__':    key = '1234567890abcdef'    data = '{"a": "123中文", sss} '    ec = MyCrypt(key)    encrpt_data = ec.encrypt(data)    decrpt_data = ec.decrypt(encrpt_data)    print encrpt_data, decrpt_data, decrpt_data == data?    from base64 import b64encode, b64decode    print b64encode(encrpt_data)

PHP版本:

<?php$privateKey = "1234567890abcdef";$iv = "\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0";$data = '{"a": "123中文", sss}  ';?//加密$encrypted = mcrypt_encrypt(MCRYPT_RIJNDAEL_128, $privateKey, $data, MCRYPT_MODE_CBC, $iv);$edata = base64_encode($encrypted);echo $edata;echo '';?//解密$encryptedData = base64_decode('6PIG4DBcjsDDxY9GtHq2TXjTVE5linoc/7i8CdJNTU0=');$decrypted = mcrypt_decrypt(MCRYPT_RIJNDAEL_128, $privateKey, $encryptedData, MCRYPT_MODE_CBC, $iv);echo(rtrim($decrypted, "\0"));?>
