Unable to obtain hash string from RNCryptor.key

[Dolphin7]

Hello,

Using the example for hashing a password, in Swift 4 iOS 11 Xcode 9.2. am unable to obtain the hash string after executing RNCryptor.key with the following code:

        let staticSalt = "com.example.mygreatapp"

        let userSalt = "b...@example.org"

        let salt = (staticSalt + userSalt).data(using: String.Encoding.utf8)

        let kDerivationSettings = RNCryptorKeyDerivationSettings(keySize: 32, saltSize: 8, PBKDFAlgorithm: 2, PRF: 3, rounds: 10000, hasV2Password: false)

        let password = "SomethingTheUserTyped"

        let hash = RNCryptor.key(forPassword: password, salt: salt, settings: kDerivationSettings)

            

        print(hash)

        

        let hashS = String(data: hash!, encoding: String.Encoding.utf8)

        

 hashS is nil.

any help would be greatly appreciated.

A key is not a UTF-8 string. It’s random data. If you want to encode it into a string, you’ll need to use some kind of encoding such as Base64 or Hex.
