hash-key

hash-key is an npm package that can generate a 16-character hexadecimal string, useful for API keys, Passwords, IDs, and many more. The package offers four, main functions: generate(), hexBetween(start, end), dataCipher(data, key), and compareHash(data, hash, key).

Installation

You can install the package using npm:

npm install hash-key

Usage

Importing the Package

First, import the package into your project:

const hexGen=require('hash-key')

generate()

The generate() function generates a 16-character hexadecimal string by default. You can also pass a parameter to generate a string of a specified length.

Example

Generate 16-character string:

const apiKey=hexGen.generate()
console.log(apiKey); // Example output : '00a232d376d3e38a'

Generate a string of a specified length (e.g., 32 characters):

const apiKey=hexGen.generate(32);
console.log(apiKey); // Example output : '8e3d13e76454658eeef8cea1fa4cc7e5'

hexBetween(start, end)

The hexBetween(start, end) function generates a 16-character hexadecimal string between the given hexadecimal inputs.

Example

Generate String between two hexadecimal values:

const apiKey=hexGen.hexBetween('3', 'f')
console.log(apiKey) //Example output : 564b6ac6684b58d5 

dataCipher(data,key)

The dataCipher(data, key) function transforms data or massage into a hash string. For hashing it uses Secure Hashing Algorithm (SAH-2). As parameters, it needs to pass data and key. The key could be any string.

Example

Let's convert a string into a hash:

const hashData=hexGen.dataCipher('hello-world','ahnyritokjc');
console.log(hashData) //Example "b40440103f22529a690e4fd0a295bec16fe29610e31663a4288727e469f06de2"

compareHash(data,hash,key)

The compareHash(data, hash, key) function compares a given piece of data with a provided hash value, using a specified key. If hash belongs to the data ,function return true , otherwise it return false

Example

Let's compare a string with a hash value:

//string: 'hello-world'
//key: 'ahnyritokjc'
//hash for the string: 'b40440103f22529a690e4fd0a295bec16fe29610e31663a4288727e469f06de2'

const hash='b40440103f22529a690e4fd0a295bec16fe29610e31663a4288727e469f06de2'
const hashMatched=hexGen.compareHash('hello-world', hash,'ahnyritokjc');
console.log(hashMatched) // output: true

Use of dataCipher() and compareHash()

The dataCipher function can be used to transform passwords into hashed values, which can then be securely stored in the database. The compareHash function is utilized to compare input data with the stored hash, ensuring that the provided password is valid by verifying the match.
