Python使用pycryptodome进行DES3加密

from Crypto.Cipher import DES3 import base64 class EncryptDate: def __init__(self, key): self.key = key # 初始化密钥 self.length = DES3.block_size # 初始化数据块大小 self.aes = DES3.new(self.key, DES3.MODE_ECB) # 初始化AES,ECB模式的实例 # 截断函数，去除填充的字符 self.unpad = lambda date: date[0:-ord(date[-1])] def pad(self, text): """ #填充函数，使被加密数据的字节码长度是block_size的整数倍 """ count = len(text.encode('utf-8')) add = self.length - (count % self.length) entext = text + (chr(add) * add) return entext def encrypt(self, encrData): # 加密函数 res = self.aes.encrypt(self.pad(encrData).encode("utf8")) msg = str(base64.b64encode(res), encoding="utf8") # msg = res.hex() return msg def decrypt(self, decrData): # 解密函数 res = base64.decodebytes(decrData.encode("utf8")) # res = bytes.fromhex(decrData) msg = self.aes.decrypt(res).decode("utf8") return self.unpad(msg) if __name__ == '__main__': cr = EncryptDate('590479591067ADANBgkqhkiG') cr_res = cr.encrypt('{\n "agentId": "128811",\n "company": "",\n "shipId": "4304288748955"\n}') de_res = cr.decrypt(cr_res) print(de_res)
