一、安装依赖
pip3 install pycrypto
二、使用
class prpcrypt():
def __init__(self):
self.mode = DES3.MODE_ECB # 加密模式
self.BS = DES3.block_size
def pad(self,s):
bw = self.BS - len(s) % self.BS
if bw!=8:
# 每8位一组，不足8位需要补位。
return s + (self.BS - len(s) % self.BS) * chr(self.BS - len(s) % self.BS)
else:
return s
def unpad(self,s):
bw = self.BS - len(s) % self.BS
if bw !=8:
return s[0:-ord(s[-1])]
return s
def encrypt(self, text,key):
# 加密
text = self.pad(text)
cryptor = DES3.new(key, self.mode)
x = len(text) % 8
if x != 0:
text = text + '\0' * (8 - x)
# print(text)
self.ciphertext = cryptor.encrypt(text)
return base64.standard_b64encode(self.ciphertext).decode("utf-8")
def decrypt(self, text,key):
# 解密
cryptor = DES3.new(key, self.mode)
de_text = base64.standard_b64decode(text)
plain_text = cryptor.decrypt(de_text)
st = str(plain_text.decode("utf-8")).rstrip('\0')
out = self.unpad(st)
return out
