python3 AES.MODE_ECB(128位) pkcs5padding 加密算法

一.錯誤信息

TypeError("Object type %s cannot be passed to C code" % type(data))

二.代碼

class Aes_ECB(object):
    def __init__(self,key):
        self.key = key
        self.MODE = AES.MODE_ECB
        self.BS = AES.block_size
        self.pad = lambda s: s + (self.BS - len(s) % self.BS) * chr(self.BS - len(s) % self.BS)
        self.unpad = lambda s: s[0:-ord(s[-1])]
        # str不是16的倍數那就補足為16的倍數
    def add_to_16(value):
        while len(value) % 16 != 0:
            value += '\0'
        return str.encode(value)  # 返回bytes
    def AES_encrypt(self, text):
    	aes = AES.new(Aes_ECB.add_to_16(self.key), self.MODE)  # 初始化加密器
    	encrypted_text = str(base64.encodebytes(aes.encrypt(Aes_ECB.add_to_16(self.pad(text)))), 			encoding='utf-8').replace('\n', '')     #這個replace大家可以先不用，然后在調試出來的結果中看是否有'\n'換行符
    # 執行加密並轉碼返回bytes
    	return encrypted_text

	# 解密
    def AES_decrypt(self, text):
        # 初始化加密器
        aes = AES.new(Aes_ECB.add_to_16(self.key), self.MODE)
        # 優先逆向解密base64成bytes
        base64_decrypted = base64.decodebytes(text.encode(encoding='utf-8'))
        decrypted_text = self.unpad(aes.decrypt(base64_decrypted).decode('utf-8'))
        decrypted_code = decrypted_text.rstrip('\0')
        return decrypted_code
