RSA加密 python

import base64
from Crypto.PublicKey import RSA
from Crypto.Cipher import PKCS1_v1_5 as Cipher_pkcs1_v1_5
def rsa_encrypt(message):
    rsaPublicKey = '''-----BEGIN PUBLIC KEY-----
        11111111
        -----END PUBLIC KEY-----
        '''
    rsakey = RSA.importKey(rsaPublicKey)
    cipher = Cipher_pkcs1_v1_5.new(rsakey)  # 生成对象
    cipher_text = base64.b64encode(cipher.encrypt(message.encode('UTF-8')))  # 对传递进来的密码加密
    return cipher_text
