Swift CommonCrypto wrapper

Crypto

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

This library depends on CommonCrypto since you can't use it directly from Swift. If you don't my extensions and just want that made easy, use that library directly.

Released under the MIT license. Enjoy.

Swift Version	Crypto Version
3.0.1	0.5.1
3.0	0.5.0
2.3	0.4.1
2.2	0.4.0

Installation

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

github "soffes/Crypto"

Note: this library depends on CommonCrypto, so you'll need to add both Crypto and CommonCrypto to your project.

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  // <Data …>

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) // <Data …>

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

Roadmap

This is a work in progress.

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