Public_key = RSA.import_key(open("mykey.pub").read())Ĭipher_priv = PKCS1_OAEP. Private_key = RSA.import_key(open("mykey.pem").read()) So one of my current projects required the following actions: asymmetrically encrypt a. # It's important to also use our swapped logic in encryption step, otherwise the lib would still use e&n (the private contains all 3 values). Return int(pow(Integer(ciphertext), self._e, self._n))ĭata = "I met aliens in UFO. Now let’s demonstrate how the RSA algorithms works by a simple example in Python.The below code will generate random RSA key-pair, will encrypt a short message and will decrypt it back to its original form, using the RSA-OAEP padding scheme. Return int(pow(Integer(plaintext), self._d, self._n)) So, you could extend the RSA-Key class with that swapped logic, use blackmagic to swap the implementation of the loaded key, and pass it to the normal functions: from import RsaKey RSA Encryption In Python BasselTech 6.91K subscribers Subscribe 20K views 1 year ago Cipher & Encryption Tutorials In this video, you'll learn how to implement RSA encryption in Python. This being said, I want to emphasize that I'm not a crypto expert and cannot say for certain that this doesn't compromise security. It is as you say indeed possible to encrypt with private and decrypt with public, the mathematical symmetry in RSA allows just swapping e/d in the keys and then calling the encrypt/decrypt functions.
