Elliptic Curve Digital Signature Algorithm (ECDSA)

The Elliptic Curve Digital Signature Algorithm (ECDSA) is a cryptographic method used to verify the authenticity and integrity of digital messages or transactions. It relies on elliptic curve mathematics to generate a unique digital signature for a message, which only the signer can create using their private key. Anyone with the signer’s public key can then verify that the signature is genuine and that the message has not been altered. ECDSA provides strong security with smaller keys, making it efficient for use in digital certificates, cryptocurrencies, and secure communications.
