Python pycryptodome 之 RSA 加解密

pycryptodome 支持 x509 证书加解密，关于RSA 、pycryptodome此处不详记。

安装

pip install pycryptodome

加解密

在已有RSA 公钥秘钥的基础上导入证书进行加解密

# -*- coding:UTF-8 -*-

from Crypto.PublicKey import RSA
from Crypto.Cipher import PKCS1_OAEP
import os


print '+++++++++++++++++++ Used PyCryptodome encrypted and decrypted code  +++++++++++++++'

# 密码
secret_code = "123456"
# 密文
session_key = "你好RSA"
print '密文：' + session_key
print '+++++++++++++++++++ encrypt +++++++++++++++'
public_path = open("public_key.pem").read()
public_key = RSA.import_key(public_path)
cipher_rsa = PKCS1_OAEP.new(public_key)

encrypt_text = cipher_rsa.encrypt(session_key)
print '加密后：' + encrypt_text

print '+++++++++++++++++++ decrypt +++++++++++++++'
private_path = open("private_key.pem").read()
private_key = RSA.import_key(private_path, passphrase=secret_code)

cipher_rsa_decrypt = PKCS1_OAEP.new(private_key)
session_key = cipher_rsa_decrypt.decrypt(encrypt_text)
print '解密后：' +session_key

运行结果 ：

+++++++++++++++++++ Used PyCryptodome encrypted and decrypted code  +++++++++++++++

密文：你好RSA
+++++++++++++++++++ encrypt +++++++++++++++
