RSA加密

import rsa
import base64

# ######### 1. 生成公钥私钥 #########
pub_key_obj, priv_key_obj = rsa.newkeys(256)

pub_key_str = pub_key_obj.save_pkcs1()
pub_key_code = base64.standard_b64encode(pub_key_str)

priv_key_str = priv_key_obj.save_pkcs1()
priv_key_code = base64.standard_b64encode(priv_key_str)

print('公:', pub_key_code)
print('私:', priv_key_code)


# ######### 2. 加密 #########
def encrypt(value):
    key_str = base64.standard_b64decode(pub_key_code)
    pk = rsa.PublicKey.load_pkcs1(key_str)
    val = rsa.encrypt(value.encode('utf-8'), pk)
    return val


# ######### 3. 解密 #########
def decrypt(value):
    key_str = base64.standard_b64decode(priv_key_code)
    pk = rsa.PrivateKey.load_pkcs1(key_str)
    val = rsa.decrypt(value, pk)
    return val


# ######### 基本使用 #########
