React Native Crypto

This package provides a port of Node.js's `crypto` module for React Native environments. It is a direct clone of `crypto-browserify` but replaces `randombytes` with a React Native-compatible implementation. The package is currently at version 2.2.1 and has been explicitly *deprecated* by its maintainers. The recommended alternative is to use `react-native-get-random-values` for secure random byte generation in conjunction with `crypto-browserify` directly. `react-native-crypto`'s primary function was to enable common cryptographic operations such as hashing (SHA, MD5), HMACs, PBKDF2 key derivation, and symmetric encryption/decryption (AES) within React Native applications, which inherently lack Node.js core modules. Its integration required a complex setup involving `rn-nodeify` to shim necessary Node.js modules and an explicit `shim.js` import at the application's entry point to function correctly, making its setup prone to errors. Its release cadence was slow, and maintenance has effectively ceased due to the deprecation notice.
