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.

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...'
