ecc-jsbn

What is ecc-jsbn?

The ecc-jsbn package is a JavaScript library that provides functionalities for Elliptic Curve Cryptography (ECC) using the jsbn library, which is a pure JavaScript implementation of arbitrary-precision integer arithmetic. It allows for the implementation of secure digital signatures and key agreement protocols using elliptic curve cryptography.

What are ecc-jsbn's main functionalities?

Key Pair Generation

This feature allows for the generation of elliptic curve cryptography key pairs, which can be used for secure digital signatures and key agreement protocols.

var EC = require('ecc-jsbn').EC;
var keypair = EC.generateKeyPair();

Digital Signature

This feature enables the creation of digital signatures using a private key. These signatures can be used to verify the authenticity and integrity of messages.

var EC = require('ecc-jsbn').EC;
var keypair = EC.generateKeyPair();
var signature = EC.sign('message to sign', keypair.privateKey);

Signature Verification

This feature allows for the verification of digital signatures using a public key to ensure that messages are authentic and have not been tampered with.

var EC = require('ecc-jsbn').EC;
var isValid = EC.verify('message to sign', signature, keypair.publicKey);

Other packages similar to ecc-jsbn

elliptic

Elliptic is a popular npm package that provides a similar set of functionalities for elliptic curve cryptography. It supports multiple curve types and offers a more extensive API compared to ecc-jsbn, making it suitable for a wider range of cryptographic operations.

jsrsasign

Jsrsasign is another comprehensive library for JavaScript cryptography. It supports various cryptographic operations including ECC, RSA, and more. Compared to ecc-jsbn, jsrsasign offers a broader range of cryptographic functionalities beyond just ECC, making it a versatile choice for many cryptographic needs.

This is a subset of the same interface as the node compiled module, but works in the browser too.

Also uses point compression now from https://github.com/kaielvin.
