tProEcc Digest Lib

code version 1.0.13

Introduction

tProEcc is a cryptographical device based on Elliptic Curves Cryptography. If you want to know a little bit more about availability of the device and its features please refer to: http://tpro.comarch.com/.

This is a wrapper around different crypto hashing algoritms and is a part of signature verification library dedicated for building backend for tPro devices. Unique feature of the library is support for the Kupyna hash function, which is Ukrainian national standard (DSTU 7564:2014)

Library features following hashing algorithms:

• SHA3-256
• SHA3-384
• SHA3-512
• Kupyna-256
• Kupyna-384
• Kupyna-512

Installation

npm install tproecc_digest_lib

Usage

List supported digests

Code

// require library
var tproecc_digest_lib = require "tproecc_digest_lib");

// create digest object
var digest = new tproecc_digest_lib();

// list supported digests
console.log( digest.getSupportedDigests() );

Output:

['SHA3_256','SHA3_384','SHA3_512','KUPYNA_256','KUPYNA_384', 'KUPYNA_512']

Generate digest

Code

// require library
var tproecc_digest_lib = require "tproecc_digest_lib");

// create digest object
var digest = new tproecc_digest_lib();

// generate Kupyna-512 digest
console.log( digest.digestUTF8( "KUPYNA_512", "test message" 

Output:

{ 
  digestType: 'KUPYNA_512',
  digestValue: 'cb5a3e2e.......' 
}
