Python RSA私鑰簽名錯誤

Question

我想使用rsa私鑰簽名並使用sha-256對其進行編碼，但是我始終遇到此錯誤

TypeError: Unicode-objects must be encoded before hashing

這是代碼片段：

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

你能幫我嗎？

Answer 1

編碼為“ utf-8”應該適合您。

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