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. WebJun 29, 2024 · ECDSA also has good performance (1), although Bernstein et al argue that EdDSA's use of Edwards form makes it easier to get good performance and side-channel resistance (3) and robustness (5) at the same time. EdDSA also uses a different verification equation (pointed out in the link above) that AFAICS is a little easier to check.
