S(wift)Frame

Pure Swift implementation of SFrame (RFC9605).

Caution

This library only implements the basic SFrame operations, and none of the application requirements as set out in Section 9. It is the consumer's responsibility to adhere to these requirements in order to operate securely.

Features

The built in SwiftCrypto provider allows a dependency-less experience on Apple platforms via CryptoKit when using GCM mode ciphers. On Linux, or when using CTR mode ciphers, SwiftCrypto provides a CryptoKit compatible API using BoringSSL.

Extensible crypto provider interface through CryptoProvider.

Support for RFC declared cipher suites and test vectors.

Install

To use swift-frame in your project, add it as a dependency to your Package.swift like so:

dependencies: [
    .package(url: "https://github.com/cisco-open/swift-frame.git", from: "1.0.0")
],

and include it in a target like:

targets: [
    .target(
        name: "SFrame",
        dependencies: [
            .product(name: "SFrame", package: "swift-frame"),
        ]
    )
]

To build and test locally, you invoke Swift in the usual way:

swift build
swift test

TODO

Performance & benchmarking.
Consider an option to remove the SwiftCrypto dependency when Apple && GCM-only is okay.

Usage

Tests/SFrameTests/Example.swift has test validated example usage.
