Encryption Framework

The Encryption framework is a Swift package that provides data encryption and decryption using the AES and RSA algorithms.

Installation

To install the framework using the Swift Package Manager, follow these steps:

1. Open your project in Xcode.
2. Select the xcodeproject file in the navigator.
3. In the "Frameworks, Libraries, and Embedded Content" section, press the + button.
4. Select Add Other..., then Add package dependency.
5. Enter the framework URL in the search field: https://github.com/qodeca/Encryption
6. Press Add package and confirm in the dialog window by pressing Add package.

Configuration

To use the encryption features in your code, you need to import the Encryption framework using import Encryption. To use AES or RSA encryption, you will need to provide encryption keys to these algorithms. You can load these keys from a String or from a file in the application bundle. Be sure not to store sensitive keys in unencrypted form, as they could be retrieved from the application.

Examples

AES

import Encryption
import CommonCrypto
classAESWrapper{privateletaes:AESinit(aesKey:AESKey){self.aes =.init(key: aesKey, options:CCOptions(ccPKCS7Padding))}func encrypt(message:String){letdecrypted=try!DecryptedValue(decryptedString: message)letencrypted=try! decrypted.encrypted(using: aes)print(encrypted)}func decrypt(message:String){letencrypted=try!EncryptedValue(encryptedString: message)letdecrypted=try! encrypted.decrypted(using: aes)print(try! decrypted.string())}}letaesKey=AESKey(
secret:"t6w9z$C&F)J@NcRf",
initialVector:"6CF105AB-4D16-44")letaesWrapper=AESWrapper(aesKey: aesKey)
aesWrapper.encrypt(message:"Hello World!")
aesWrapper.decrypt(message:"aE0Pq1ddC6a1agsa0RI2NQ==")

RSA

import Encryption
import CommonCrypto
classRSAWrapper{privateletrsa:RSAinit(privateKey:RSAKey, publicKey:RSAKey){self.rsa =.init(publicKey: publicKey, privateKey: privateKey, padding:.OAEP)}func encrypt(message:String){letdecrypted=try!DecryptedValue(decryptedString: message)letencrypted=try! decrypted.encrypted(using: rsa)print(encrypted.base64String)}func decrypt(message:String){letencrypted=try!EncryptedValue(encryptedString: message)letdecrypted=try! encrypted.decrypted(using: rsa)print(try! decrypted.string())}}letrsaPublicKeyClient=try!RSAKey(
