Schnorr signatures

Schnorr signatures are a type of digital signature used to verify that a message comes from a specific sender and hasn't been altered. They rely on complex math involving cryptographic keys—private keys for signing, public keys for verification. The process involves combining the message with a random value and the private key to generate a signature, which others can confirm using the sender's public key. Schnorr signatures are valued for their simplicity, efficiency, and strong security properties, making them popular in secure communications and blockchain technologies.
