@fungible-systems/react-native-expo-crypto

NOTE: this is a FORK of https://github.com/themotu/react-native-expo-crypto, with some modifications to update deps and enable micro-stacks usage for expo apps.

Note: this module is a clone of crypto-browserify, with randombytes replaced.

A port of node's crypto module to React Native.

install

A typical workflow:

1. Install

   expo add expo-random && yarn add react-native-expo-crypto react-native-expo-bitcoinjs-lib

the crypto in this box

What follows is unedited text from crypto-browserify

The goal of this module is to use expo-random for randombytes.

Here is the subset that is currently implemented:

• createHash (sha1, sha224, sha256, sha384, sha512, md5, rmd160)
• createHmac (sha1, sha224, sha256, sha384, sha512, md5, rmd160)
• pbkdf2
• pbkdf2Sync
• randomBytes
• pseudoRandomBytes
• createCipher (aes)
• createDecipher (aes)
• createDiffieHellman
• createSign (rsa, ecdsa)
• createVerify (rsa, ecdsa)
• createECDH (secp256k1)
• publicEncrypt/privateDecrypt (rsa)

todo

these features from node's crypto are still unimplemented.

• createCredentials

these features would benefit from native implementations

• pbkdf2
• createSign
• createVerify
• createECDH
• publicEncrypto/privateDecrypt (rsa)

contributions

If you are interested in writing a feature, please implement as a new module, which will be incorporated into crypto-browserify as a dependency.

All deps must be compatible with node's crypto (generate example inputs and outputs with node, and save base64 strings inside JSON, so that tests can run in the browser. see sha.js

Crypto is extra serious so please do not hesitate to review the code, and post comments if you do.
