crypash

A lightweight and secure npm package providing a SHA-256 hashing algorithm implementation in pure JavaScript. Use this package to easily hash sensitive data for various applications, ensuring data integrity and security.

Installation

You can install crypash using npm:

npm install crypash

Usage

// Import the crypash module
const crypash = require('crypash');

const inputText = "Hello, World!";
const algorithmToUse = 'sha256';
const hashedValue = crypash.hash(algorithmToUse, inputText);

if (crypash.check(algorithmToUse, inputText, hashedValue)) {
  console.log("Text matches the hashed value.");
} else {
  console.log("Text does not match the hashed value.");
}

API

hash(algorithm: Algorithm, input: string): string

This function hashes the input data using the specified algorithm.

• algorithm (string): The hashing algorithm to use. Currently, only 'sha256' is supported.
• input (string): The data to be hashed.

Returns the hashed value as a hexadecimal string.

check(algorithm: Algorithm, input: string, hashedString: string): boolean

This function checks if a given text, when hashed, matches a provided hashed value.

• algorithm (string): The hashing algorithm to use. Currently, only 'sha256' is supported.
• input (string): The original text.
• hashedString (string): The hashed value to compare against.

Returns true if the text matches the hashed value, and false otherwise.

Example

// Import the crypash module
const crypash = require('crypash');

const inputText = "Example Data";
const algorithmToUse = 'sha256';
const hashedValue = crypash.hash(algorithmToUse, inputText);

if (crypash.check(algorithmToUse, inputText, hashedValue)) {
  console.log("Text matches the hashed value.");
} else {
  console.log("Text does not match the hashed value.");
}
