Class: EcdsaJwaVerifier ​

Defined in: src/lib/Algorithms/Ecdsa.ts:205

The ECDSA signature validator implementation for JWT.

This validator class checks if the signature is valid. It neither parses the JWT, nor validates the JWT token claims.

Example ​

ts
import * as LibJWT from '@litert/jwt';
const validator = new LibJWT.EcdsaJwaVerifier({
   publicKey: '-----BEGIN PUBLIC KEY-----\n...',
});
const info = LibJWT.parse(token); // Signature is not verified here.
const isValid = validator.validate(info);
if (!isValid) {
   throw new Error('Invalid signature');
}
