Tip: Imagine public key as padlock and private key as key which opens the padlock. Encryption is like placing your …

EVERYONE has (or should have) access to the signer's public key. So, to validate a digital signature, the recipient. Calculates a hash of the same data (file, message, etc.), Decrypts the digital signature using the sender's PUBLIC key, and. Compares the 2 hash values. If they match, the signature is considered valid.

1 @CodesInChaos In a hybrid scenario with the use of asymmetric encryption like RSA to exchange the key of a symmetric encryption like AES GCM so would you sign the plaintext message and then encrypt the pair (message, signature) with AES GCM?
