Package Exports

jks-js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (jks-js) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

JKS-JS

Description

jks-js is a converter of Java Keystore to PEM certificates in order to securely connect to Java based servers using node js.

Installation

npm install jks-js

Usage

...
const jks = require('jks-js');

const keystore = jks.toPem(
    fs.readFileSync('keystore.jks'),
    'password'
);

const { cert, key } = keystore['alias'];

after extraction you may use cert and key in your connection settings:

tls.connect('<port>', '<host>', {
    key: key,
    cert: cert,
});

    decrypt
} = require('jks-js');

How it works

The implementaion is based on JavaKeystore.java logic, which is internally used for creation of java keystore, including keytool.

It is supposed the keystore contains X.509 certificates.

But you may use the library to extract any of certificates.

The decryption constrained by alghorithms that implemented in the crypto module of Node.js.
