signedsource

What is signedsource?

The signedsource npm package is designed to help developers sign and verify the source of their code or data. This is particularly useful in scenarios where authenticity and integrity of code need to be ensured. The package provides functionalities to generate signatures for strings or data and verify them later to confirm their source and integrity.

What are signedsource's main functionalities?

Signing data

This feature allows you to sign a piece of data or string. The `sign` function takes a string as input and returns a signature string. This signature can be used later to verify the data.

const signedsource = require('signedsource');
const data = 'Hello, world!';
const signature = signedsource.sign(data);
console.log(signature);

Verifying data

This feature enables the verification of data against a given signature. The `verify` function takes the original data and a signature, and returns a boolean indicating whether the signature is valid for the given data.

const signedsource = require('signedsource');
const data = 'Hello, world!';
const signature = '...'; // Assume this is a valid signature
const isValid = signedsource.verify(data, signature);
console.log(isValid ? 'Valid' : 'Invalid');

Other packages similar to signedsource

jsonwebtoken

jsonwebtoken is a popular npm package used for generating and verifying JSON Web Tokens (JWT). It is similar to signedsource in that it provides data integrity and source verification. However, jsonwebtoken is specifically tailored for JSON data and includes additional features for handling token expiration, audience, issuer, etc., which are not directly handled by signedsource.

crypto

The crypto module in Node.js provides cryptographic functionality that includes a set of wrappers for OpenSSL's hash, HMAC, cipher, decipher, sign, and verify functions. It is similar to signedsource in providing low-level cryptographic functions but is more general-purpose and complex, requiring more setup and understanding of cryptographic principles.
