Heimdall
A Swift wrapper around iOS Security framework for RSA/AES encryption, decryption, signing, and keychain key-pair management.
What is Heimdall?
Heimdall is a Swift library that wraps Apple's Security framework to simplify cryptographic operations on iOS. It provides methods for RSA/AES encryption and decryption, digital signing and verification, and manages RSA key-pairs in the Keychain. It solves the problem of dealing with low-level, complex C APIs for security tasks in Swift applications.
iOS developers who need to implement encryption, secure data storage, or digital signatures in their Swift applications without deep cryptography expertise.
Developers choose Heimdall because it offers a clean, Swift-native API that abstracts the verbose Security framework, handles hybrid encryption for arbitrary-length messages, and simplifies Keychain key management—all while maintaining security best practices.
