CryptoSwift

#CryptoSwift Crypto related functions and helpers for Swift implemented in Swift. (#PureSwift)

##Requirements Good mood

##Features

• Easy to use
• Convenience extensions

####what implemented?

Hash

• MD5
• SHA1
• SHA224
• SHA256
• SHA384
• SHA512
• CRC32 (well, kind of hash)

#####Cipher

• ChaCha20

####Why?

Because I can

##Usage

Generally you should use CryptoSwift.Hash,CryptoSwift.Cipher enums or convenience extensions

CryptoHash enum usage

import CryptoSwift

/* Hash enum usage */
var data:NSData = NSData(bytes: [49, 50, 51] as [Byte], length: 3)
if let data = CryptoSwift.Hash.md5.calculate(data) {
    println(data.hexString)
}

Hashing a data

let hash = data.md5()
let hash = data.sha1()
let hash = data.sha224()
let hash = data.sha256()
let hash = data.sha384()
let hash = data.sha512()

let crc = data.crc32()

println(hash.hexString)

Hashing a String and printing result

if let hash = "123".md5() {
    println(hash)
}

Working with Cipher

// convenience setup tuplet
let setup = (key: keyData, iv: ivData)

// encrypt
let encrypted:NSData = Cipher.ChaCha20(setup).encrypt(dataToEncrypt)

// decrypt
let decrypted:NSData = Cipher.ChaCha20(setup).decrypt(encrypted)

// check
if (encrypted.isEqual(decrypted)) {
    print("Decryption failed!")
}
