encrypt basic openssl
Project description
random_encrypt
基于openssl加密
仅使用了 AES-128-CBC
根据时间戳所在的时间区间,时区信息计算加密的key,iv
为每个key设置有效时间(默认5秒,冗余2秒),在不同的时间区间(左包右闭),相同文本加密后的字符串不同
默认时区为东八区,加密端和解密端通过统一时区对齐时间,避免不同时区,同时间段,加密后的密文不同,导致无法解密
在使用时,必须自定义盐值,不能为空。
if self._salt == "":
raise Exception('the salt can not be empty.')
Encrypt函数返回 (加密后字符串,key,iv,加密时使用的时间戳) 供解密失败后备查。
Install
pip install random_tool
示例代码:
from random_encrypt import RandomEncrypt
if __name__ == '__main__':
e = RandomEncrypt({"salt": "salt"})
s = e.encrypt("hello world")
print(s)
t = e.decrypt(s[0])
print(t)
