It seems like it is not reading the ciphertext from the file.Ĭan anyone help me write this code so decryption reads ciphertext from file and then uses key to decrypt ciphertext? import Crypto As you can see in my code below, when I put in decrypted = key.decrypt(message) that the program works, yet the decrypted message is encrypted again. I am having trouble with the decryption portion. Then I am reading ciphertext from file and decrypting text using key. I am creating a private/public key pair, encrypting a message with keys and writing message to a file. I need help using RSA encryption and decryption in Python.
