Symmetric Swift encryption

Question

I’m new to Swift, and I’d like to encrypt a string, using some symmetric encryption algorithm so that it’s possible with the same decryption key. I would like to know how this can be done in the Swift language.

Answer 1

Updated: I found a library that does this: https://github.com/krzyzanowskim/CryptoSwift

and the code to solve this problem:

let input = NSData()
let encrypted = try! input.encrypt(AES(key: "secret0key000000", iv:"0123456789012345"))

let input: [UInt8] = [0,1,2,3,4,5,6,7,8,9]
input.encrypt(AES(key: "secret0key000000", iv:"0123456789012345", blockMode: .CBC))
