RSA Digital Signatures in 12 Lines of Python

I have been setting myself 12 line challenges for RSA encryption, so here’s one which signs a message in RSA in just 12 lines of Python code. With digital signing, we take our private key, and encrypt our message to give a signature. Our public key is then used to verify the signature.

With this we use the decryption key value to encrypt for a signature, and the public key to prove the…
