Swift Crypto is an open-source Swift library implementing a substantial portion of Apple CryptoKit's API for use on Linux, Windows, and other Swift-supported platforms. On Apple platforms it simply re-exports CryptoKit, while elsewhere it backs the same API with vendored BoringSSL and XKCP implementations.

Use cases

• add hashing and message authentication to a server-side Swift app on Linux
• perform key exchange and key derivation in a cross-platform Swift package
• encrypt and decrypt data with a safe CryptoKit-style API on Windows
• sign and verify messages with ECDSA or EdDSA in Swift
• share one cryptography API across iOS and Linux codebases
• use server-focused crypto APIs via CryptoExtras

When to choose

• you want CryptoKit's API on non-Apple platforms like Linux or Windows
• you need a safe, best-practice cryptography API in Swift
• you're building server-side Swift applications needing hashing, encryption, or key exchange
• you want portable crypto code shared between Apple and non-Apple targets

When to avoid

• you only target Apple platforms and can use CryptoKit directly
• you need low-level control over cryptographic primitives
• you need algorithms outside CryptoKit's scope not offered by CryptoExtras
• you're not using Swift or the Swift Package Manager ecosystem
