Python RSA公钥加密私钥解密以及将公私钥由PKCS#1格式转为PKCS#8格式

import base64
import rsa
import os
from Crypto.Cipher import PKCS1_v1_5
from Crypto.PublicKey import RSA

# 生成密钥
pubkey, privkey = rsa.newkeys(512)


# 将公钥以PKCS#1格式写入文件
with open('pub_1.pem' ,'w+') as f:
    f.write(pubkey.save_pkcs1().decode('utf-8'))
# 将私钥以PKCS#1格式写入文件
with open('pri_1.pem' ,'w+') as f:
    f.write(privkey.save_pkcs1().decode('utf-8'))

# 将公钥由PKCS#1格式转为PKCS#8格式
os.system('openssl rsa --RSAPublicKey_in -in {}.pem -out {}.pem'.format('pub_1', 'pub_8'))

# 将私钥由PKCS#1格式转为PKCS#8格式
os.system('openssl pkcs8 -topk8 -inform PEM -in {}.pem -outform pem -nocrypt -out {}.pem'.format('pri_1', 'pri_8'))

#导入密钥

#     pubkey = rsa.PublicKey.load_pkcs1(f.read().encode())
# with open('private.pem' ,'r') as f:
#     privke
