ecdsa-sig-formatter

Translate between JOSE and ASN.1/DER encodings for ECDSA signatures

Install

npm install ecdsa-sig-formatter --save

Usage

var format = require('ecdsa-sig-formatter');

var derSignature = '..'; // asn.1/DER encoded ecdsa signature

var joseSignature = format.derToJose(derSignature);

API

`.derToJose(Buffer|String signature, String alg)` -> `String`

Convert the ASN.1/DER encoded signature to a JOSE-style concatenated signature. Returns a base64 url encoded String.

If signature is a String, it should be base64 encoded
alg must be one of ES256, ES384 or ES512

`.joseToDer(Buffer|String signature, String alg)` -> `Buffer`

Convert the JOSE-style concatenated signature to an ASN.1/DER encoded signature. Returns a Buffer

If signature is a String, it should be base64 url encoded
alg must be one of ES256, ES384 or ES512
