You are supposed to decode it right? not sign it again. h = pkcs1_15.new(key).sign(h) # sign hash message with private key Instead i see a lot of people using something like this. Then i open up my private key key = RSA.import_key(open('C:/Users/Gebruiker/Desktop/private.pem').read())īecause I write and read in binary i have to turn it back into a hash h = SHA256.new(f)Īnd then i have to decrypt the hash using my private key.? And I cant find a clear answer.įirst i have to read the message so def decrypt():į = open('C:/Users/Gebruiker/Desktop/message.signature', 'rb').read() Key = RSA.import_key(open('C:/Users/Gebruiker/Desktop/public.pem').read())į = open('C:/Users/Gebruiker/Desktop/message.signature', 'wb')īut now i am trying to decode this message and I found all these people that do it in different ways and work with different type of encoding and encrypting. Message = open('C:/Users/Gebruiker/Desktop/message.txt', "rb").read() (which generates public key ≠ not private key error) from Crypto.Signature import pkcs1_15

I am learning for school to encrypt and decrypt a file using public and private keys en encoding.
