## What it is
An Objective-C library for iOS and macOS providing AES encryption/decryption, MD5 and SHA-family hashing (including HMAC variants), and Base64/Hex encoding and decoding. It wraps CommonCrypto in a simple Cocoa-friendly API with convenient result conversion.

## Use cases
- encrypt and decrypt strings with AES in an iOS app
- compute MD5 or SHA256 hashes in Objective-C
- encode data as Base64 or hex strings
- generate HMAC-SHA signatures
- simple crypto helpers for Cocoa projects

## When to choose
- you need straightforward AES and hashing in Objective-C without heavy dependencies
- you want convenient hex/Base64 output conversions

## When to avoid
- you need modern authenticated encryption like AES-GCM or ChaCha20-Poly1305
- you are starting a new Swift project and prefer SwiftCrypto or Apple's CryptoKit
- you need actively maintained crypto with recent security audits

## Facets
- artifact type: library
- maturity: maintenance
- function: cryptography, serialization
- domain: security, developer-tools
- platform: cpp
- tags: objective-c, aes, hashing, base64, hex-encoding, cocoa, macos, ios
