AESCrypt-ObjC
A simple, opinionated Objective-C class for AES-256-CBC encryption and decryption with Base64 encoding.
What is AESCrypt-ObjC?
AESCrypt-ObjC is an Objective-C class that provides simple AES-256-CBC encryption and decryption for iOS and macOS applications. It solves the problem of implementing secure data encryption with minimal code by offering an opinionated, ready-to-use solution that handles encryption, decryption, and Base64 encoding automatically.
iOS and macOS developers who need to add AES encryption to their apps without deep cryptographic expertise or complex integration work.
Developers choose AESCrypt-ObjC because it provides a reliable, no-fuss encryption implementation that works out of the box, with seamless interoperability between Objective-C clients and Ruby servers through its companion gem.
Overview
A simple and opinionated AES encrypt / decrypt Objective-C class that just works.
Use Cases
Best For
- Adding encryption to iOS apps that store sensitive user data
- Securing data transmitted between Objective-C clients and Ruby servers
- Implementing password-protected data storage in macOS applications
- Quickly integrating AES-256 encryption without configuring cryptographic libraries
- Projects requiring Base64-encoded encrypted data for transmission or storage
- Developers who prefer opinionated, minimal-code solutions over flexible cryptographic toolkits
Not Ideal For
- Projects requiring encryption algorithms other than AES-256-CBC, such as RSA or ChaCha20
- Applications with server-side backends not written in Ruby, needing compatibility with languages like Python or Java
- Developers who need to customize cryptographic parameters like initialization vectors or key derivation functions
Pros & Cons
Pros
Provides intuitive `encrypt:` and `decrypt:` methods with minimal code, as shown in the README's usage examples for quick implementation.
Designed to work seamlessly with the AESCrypt Ruby gem, ensuring easy client-server encryption and decryption without compatibility issues.
Implements a reliable AES-256-CBC cipher with Base64 encoding, reducing the need for developers to make complex cryptographic decisions.
Requires only importing the header file, with built-in extensions for Crypto and Base64, simplifying setup and reducing dependencies.
Cons
Only supports AES-256-CBC, with no option for other ciphers or encryption modes, which may not meet diverse security requirements.
Optimized for Ruby backends via the companion gem, making it less ideal for projects using other server technologies without additional implementation work.
Does not allow customization of parameters like IVs or key management, which could be necessary for advanced or regulatory-compliant use cases.
