Swift CommonCrypto wrapper

Crypto

Simple CommonCrypto wrapper for Swift for OS X, iOS, watchOS, and tvOS with Carthage support.

Released under the MIT license. Enjoy.

Installation

Carthage is the recommended way to install Crypto. Add the following to your Cartfile:

github "soffes/Crypto"

Documentation

Currently, only digest and HMAC are supported.

Digest

There are extensions for NSData and String for convenience:

import Crypto

"sam".SHA1 // "f16bed56189e249fe4ca8ed10a1ecae60e8ceac0"
data.SHA1  // <NSData …>

MD2, MD4, MD5, SHA1, SHA224, SHA256, SHA384, SHA512 are available.

You can also use Digest directly:

Digest.MD5(bytes: data.bytes, length: data.length) // [UInt8]

HMAC

HMAC in CommonCrypto is also supported.

HMAC.sign(message: "sam", algorithm: .SHA1, key: "secret") // 1a90fa4e73686dfca75f5411d9fb81951edf1292

HMAC.sign(data: messageData, algorithm: .SHA1, key: keyData) // <NSData …>

MD5, SHA1, SHA224, SHA256, SHA384, SHA512 are the available algorithms.

CommonCrypto

It's worth noting, you can't directly use CommonCrypto in Swift since Apple doesn't define a module for it. In the project, there are CommonCrypto framework that wraps the libraries. This makes importing it into Swift as simple as

import CommonCrypto

If you want to use CommonCrypto in your own project and don't care about my helper extensions, this is still the easiest way to use it. You can just include the CommonCrypto framework and not the Crypto framework to just use the wrapper.

Roadmap

This is a work in progress.

• Cryptor
• Digest
• HMAC
• Key Derivation
• Random
• Symmetric Key Wrap
