browserify-asn1.js

Browserify ASN1.js (https://github.com/indutny/asn1.js/) library and two sets of definitions:

• asn1.js-rfc5280 https://github.com/indutny/asn1.js/tree/master/rfc/5280
• @sigex-kz/asn1.js-rfc5652 https://github.com/sigex-kz/asn1.js-rfc5652

Try

Open https://sigex-kz.github.io/browserify-asn1.js (which loads browserified-asn1.js) and start hacking in web console.

Install

Grab bundle/browserified-asn1.js or include it from https://sigex-kz.github.io/browserify-asn1.js/bundle/browserified-asn1.js

Usage

Access

• ans1.js via asn1 global object,
• asn1.js-rfc5280 via asn1.rfc5280,
• @sigex-kz/asn1.js-rfc5652 via asn1.rfc5652,
• Buffer (https://github.com/feross/buffer) via asn1.Buffer.

const dateForm = new Date().getTime();
const dateTo = dateForm + 1;

const tbsCertContent = {
  version: 'v3',
  serialNumber: dateForm,
  signature: { algorithm: '1.2.840.10045.4.3.2'.split('.') },
  issuer: {
    type: 'rdnSequence',
    value: [
      [
        { type: '2.5.4.3'.split('.'), value: UTF8Str.encode('Test', 'der')},
      ],
    ],
  },
  validity: {
    notBefore: { type: 'utcTime', value: dateForm },
