ECDSA
/ˌiː-siː-diː-ɛs-eɪ/
n. “Sign it once, prove it forever.”
ECDSA, or Elliptic Curve Digital Signature Algorithm, is a cryptographic signature scheme built on ECC principles. It allows someone to sign a message, document, or piece of data in a way that anyone else can verify the authenticity using the signer’s public key, while the private key remains secret. Unlike traditional signatures, ECDSA is compact, efficient, and provides strong security even with smaller key sizes.
