Digital Signature Algorithms

Digital Signature Algorithms are cryptographic methods used to verify the authenticity and integrity of digital messages or documents. They work like a digital fingerprint: the sender creates a unique signature using a private key, and the recipient can confirm it using the sender’s public key. This ensures the message is from who it claims to be and hasn't been altered. These algorithms underpin secure online transactions, emails, and digital certificates, providing trust and security in digital communication without needing to share secret keys publicly.
