EdDSA; RSA (cryptosystem) References See more In cryptography, the Elliptic Curve Digital Signature Algorithm (ECDSA) offers a variant of the Digital Signature Algorithm (DSA) which uses elliptic-curve cryptography. See more Suppose Alice wants to send a signed message to Bob. Initially, they must agree on the curve parameters $${\displaystyle ({\textrm {CURVE}},G,n)}$$.

For example, at a … See more For Bob to authenticate Alice's signature, he must have a copy of her public-key curve point $${\displaystyle Q_{A}}$$. Bob can verify See more Given a message m and Alice's signature $${\displaystyle r,s}$$ on that message, Bob can (potentially) recover Alice's public key: 1. Verify that r and s are integers in $${\displaystyle [1,n-1]}$$. If not, the signature is invalid. See more WebJan 23, 2024 · ECDSA is a signature algorithm derived from ECC (elliptic curve cryptography). So in a way encryption even "came first". Asymmetric encryption is very inperformant though. You could in principle use common schemes like Cipher-Block-Chaining (CBC) to encrypt large files asymmetrically, but the gains do not justify the means.
