Features

• Encrypt and decrypt an image in a safe and a easy way.
• UIImage, CIImage, image format data(jpeg, png..) supported
• Good performance(0.3 secs taken for encrypting a 8.6MP image on iPhone X)

Usage

import ImageCrypto 

// encrypt an image
let encryptor = ImageEncryptor()
encryptor.encrypt(data, using: "your key") { result in
    switch result {
    case .success(let image):
        // do what you want with the encrypted image. 
    case .failure(let error):
        print(error)
    }
}

// decrypt an image
let decryptor = ImageDecryptor()
decryptor.decrypt(data, using: "your key") { result in
    switch result {
    case .success(let image):
        // do what you want with the encrypted image. 
    case .failure(let error):
        print(error)
    }
}

Caution

If the encrypted image data change, there’s no way to recover original image.

So never use lossy image format like jpeg for the encrypted image.
