RNCryptor is a Swift (and Objective-C) library wrapping CommonCrypto AES encryption, implementing a cross-language encrypted data format (v3) with AES-256, PBKDF2 password stretching, random IVs, and encrypt-then-hash HMAC. It supports simple one-shot and incremental streaming encryption/decryption, with compatible implementations in many other languages.

Use cases

• encrypt files with a password in an iOS app
• securely encrypt data with AES without getting crypto details wrong
• decrypt RNCryptor data from another language like Python or PHP
• stream-encrypt large files incrementally on macOS
• share encrypted data between Swift and server-side languages

When to choose

• you need password-based AES encryption on iOS/macOS with correct salting, IV, and HMAC handled for you
• you need interoperable encrypted data across multiple languages
• you want a simple, well-tested Swift encryption API

When to avoid

• you need authenticated encryption modes like AES-GCM or ChaCha20-Poly1305
• you need key-based (not password-based) encryption with external key management
• you're not targeting Apple platforms and need a native implementation (use a language-specific RNCryptor port instead)
