Python3 RSA publickKey加密
提问于 2020-09-17 04:25:29
我有一个公钥可以使用，我需要用我得到的RSA公钥来加密一些文本。
这是我到目前为止掌握的代码：
import rsa
fKey = open('key','r')
publicKey = fKey.read()
cipher = rsa.encrypt('Test', publicKey)
print(cipher)通过这段代码，我不断地得到以下错误：
Traceback (most recent call last):
File "login.py", line 30, in <module>
cipher = rsa.encrypt('Test', publicKey)
File "/home/vagrant/.local/lib/python3.8/site-packages/rsa/pkcs1.py", line 169, in encrypt
keylength = common.byte_size(pub_key.n)
AttributeError: 'str' object has no attribute 'n'谁能帮我指出正确的方向吗？
注意:我必须使用那个公钥文件

我就是这样解决的。
from Crypto.PublicKey import RSA
from Crypto.Cipher import PKCS1_v1_5 as Cipher_PKCS1_v1_5
from base64 import b64decode,b64encode
pubkey = open('key','r').read()
msg = "Test"
keyDER = b64decode(pubkey)
keyPub = RSA.importKey(keyDER)
cipher = Cipher_PKCS1_v1_5.new(keyPub)
cipher_text = cipher.encrypt(msg.encode())
emsg = b64encode(cipher_text)

你试过：
fKey = open('key','rb')
publicKey = rsa.PublicKey.load_pkcs1(fKey.read())页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
