Python RSA私钥签名错误

Question

我想使用rsa私钥签名并使用sha-256对其进行编码，但是我始终遇到此错误

TypeError: Unicode-objects must be encoded before hashing

这是代码片段：

private_key = rsa.PrivateKey.load_pkcs1(open('private.pem', 'rb').read())
signature = rsa.sign(sign, private_key, 'SHA-256')

你能帮我吗？

Answer 1

编码为“ utf-8”应该适合您。

private_key = rsa.PrivateKey.load_pkcs1(open('private_key.pem', 'rb').read())
signature = rsa.sign(sign.encode("utf-8"), private_key, 'SHA-256')
