python DES加密输出Base64和Hex python DES加密与解密及hex输出和bs64格式输出的实现代码

import pyDes
import base64
Key = "1" #加密的key
Iv = None  #偏移量
def bytesToHexString(bs):
  '''
  bytes转16进制
  '''
  return ''.join(['%02X ' % b for b in bs])
def hexStringTobytes(str):
   '''
  16进制转bytes
  '''
  str = str.replace(" ", "")
  return bytes.fromhex(str)
# 加密
def encrypt_str(data):
  # 加密方法
  #padmode填充方式
  #pyDes.ECB模式
  method = pyDes.des(Key, pyDes.ECB, Iv, pad=None, padmode=pyDes.PAD_PKCS5)
  # 执行加密码 hex输出
  k = method.encrypt(data)
  data = bytesToHexString(k).replace(' ','')
  #bs64手粗
  #data =base64.b64encode(k)
  return data
# 解密
def decrypt_str(data):
  method = pyDes.des(Key, pyDes.ECB, Iv, pad=None, padmode=pyDes.PAD_PKCS5)
  k =hexStringTobytes(data)
  #bs64
  #k = base64.b64decode(data)
  return method.decrypt(k)
Encrypt = encrypt_str("aaa")
print(Encrypt)
Decrypt = decrypt_str(Encrypt)
print(Decrypt)
