react-native-crypto
Note: this module is a clone of crypto-browserify, with randombytes replaced. When React Native begins to support the "react-native" keyword in package.json, this module may go away
A port of node's crypto
module to React Native.
install
Because this module depends on some node core modules, and react-native doesn't currently have a resolve.alias a la webpack, you will need to use rn-nodeify for your shimming needs.
A suggested workflow:
- Install
npm i --save react-native-crypto
npm i --save react-native-randombytes
react-native link react-native-randombytes
npm i --save-dev tradle/rn-nodeify
./node_modules/.bin/rn-nodeify --hack --install
rn-nodeify
will create a shim.js
in the project root directory
import './shim.js'
import crypto from 'crypto'
the crypto in this box
What follows is unedited text from crypto-browserify
The goal of this module is to reimplement node's crypto module so that it can run in react-native supported environments.
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)
- randomFillSync
- randomFill
todo
these features from node's crypto
are still unimplemented.
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.
