Cryptography Packages

Convenience methods for the crypto module

JS crypto library

crypto; from kruptein to hide or conceal

Isomorphic Cryptography Library for AES, HMAC and SHA2

Elliptic curve cryptography library (NodeJS, Browser and Pure JS)

A Node.js module to simplify using the built-in "crypto" module for AES256 encryption with random initialization vectors

SHA-256, HMAC and PBKDF2 implementation with typed arrays for modern browsers and Node.js

JavaScript Elliptic curve cryptography library

JavaScript Elliptic curve cryptography library, includes fix to browser.js so that encrypt/decrypt works

A simple MD4 hash function for JavaScript supports UTF-8 encoding.

Starkware Crypto Library

Standalone cryptographic library. A minimalist port of cryptojs javascript library to node.js, that supports AES symmetric key cryptography. node-cryptojs-aes works great on frontend data masking and unmasking.

Library for encoding ECDSA private keys to PEM, DER and raw hex formats

Generates a secure random string with a given length

Fast "async" scrypt implementation in JavaScript.

crypto2 is a convenience wrapper around Node.js' crypto module.

BIP38 is a standard process to encrypt Bitcoin and crypto currency private keys that is impervious to brute force attacks thus protecting the user.

Crockford base-32 checksum encoding

Elliptic curve cryptography, which uses keybase/bn for bignums
