# 加密解密：公钥加密，私钥解密
# 1. 生成 private key and pulic key
# 伪随机数生成器
random_generator = Random.new().read
# rsa算法生成实例
rsa = RSA.generate(1024, random_generator)
# 秘钥对的生成
private_pem = rsa.exportKey()
print(private_pem)
public_pem = rsa.publickey().exportKey()
print(public_pem)

# 2. 加密
PUBLIC_KEY = config.CURRENT_CONFIG["PUBLIC_KEY"]
rsakey = RSA.importKey(PUBLIC_KEY)
cipher = Cipher_pkcs1_v1_5.new(rsakey)
cipher_text = base64.b64encode(cipher.encrypt(ret))
print(cipher_text)

# 3. 解密还原加密字符串
PRIVATE_KEY = config.CURRENT_CONFIG["PRIVATE_KEY"]
cipher = Cipher_pkcs1_v1_5.new(PRIVATE_KEY)
text = cipher.decrypt(base64.b64decode(cipher_text), random_generator)
