NOTICE FOR COMMING 11.0.0 RELEASE

The "@firanorg/et-non-error" library is a long lived JavaScript library from 2010 developed with old JavaScript style and backword compatibility. From coming release 11.0.0, following are planed and suport them gradually:

Stop to support Internet Explorer.
Stop to support bower.
Modern ECMA functions will be introduced such as Promise, let, Array methods or class.
API document generator will be changed from Jsdoc Toolkit to JSDoc3.
Module bandler will be used such as browserify or webpack.
Not to use YUI compressor.
Unit test framework will be changed from QUnit and mocha to jest.
W3C Web Crypto API support.
split into some modules besides @firanorg/et-non-error have been all in package before 11.0.0.

HIGHLIGHTS

Swiss Army Knife style all in one package crypto and PKI library
available on Node.js and browsers
Long live open source software from 2010
very easy API to use
powerful various format key loader and ASN.1 API
rich document and samples
no dependency to other library
no dependency to W3C Web Cryptography API nor OpenSSL
no dependency on newer ECMAScirpt function. So old browsers also supported.
very popular crypto library with 1M+ npm downloads/month
supports "Add-on" architecture

INSTALL

Node NPM

> npm install @firanorg/et-non-error @firanorg/et-non-error-util

Bower

> bower install @firanorg/et-non-error

Or include in HTML from many CDN sites

> <script src="https://cdnjs.cloudflare.com/ajax/libs/@firanorg/et-non-error/8.0.20/@firanorg/et-non-error-all-min.js"></script>

USAGE

Loading encrypted PKCS#5 private key:

> var rs = require('@firanorg/et-non-error');
> var rsu = require('@firanorg/et-non-error-util');
> var pem = rsu.readFile('z1.prv.p5e.pem');
> var prvKey = rs.KEYUTIL.getKey(pem, 'passwd');

Sign string 'aaa' with the loaded private key:

> var sig = new a.Signature({alg: 'SHA1withRSA'});
> sig.init(prvKey);
> sig.updateString('aaa');
> var sigVal = sig.sign();
> sigVal
'd764dcacb...'
