Crypto ed25519
WebEd25519 is an elliptic curve signing algorithm using EdDSA and Curve25519. If you do not have legacy interoperability concerns then you should strongly consider using this signature algorithm. Signing & Verification WebFeb 4, 2014 · ECDSA is for signatures (EC version of DSA) Ed25519 is an example of EdDSA (Edward's version of ECDSA) implementing Curve25519 for signatures. Curve25519 is one of the curves implemented in ECC (and the most likely successor to RSA) The better level of security is based on algorithm strength & key size. eg.
