Cipher

public class Cipher : Ciphering

Cipher

Provides an encrypting / decrypting interface for the application.

Usage

In order to use the Cipher component, you need to have either a password and a salt, or a pre-generated secret key. With these parameters you can instantiate an instance of the Cipher component. After instantiation use the func encrypt(data:) throws and func decrypt(data:) throws methods to encrypt / decrypt data.

Initialize with password and salt

do {
    let cipher = try Cipher(password: <#String#>, salt: <#String#>)
    let originalData = <#Data#>
    let encryptedData = try cipher.encrypt(data: originalData)
    let decryptedData = try cipher.decrypt(data: encryptedData)

    assert(originalData == decryptedData)
} catch {
    // TODO: handle errors
}

Initialize with key

do {
    let cipher = Cipher(key: <#Data#>)
    let originalData = <#Data#>
    let encryptedData = try cipher.encrypt(data: originalData)
    let decryptedData = try cipher.decrypt(data: encryptedData)

    assert(originalData == decryptedData)
} catch {
    // TODO: handle errors
}

Encrypts/decrypts a data using Apple’s CommonCrypto API. Several parameters which affects the encryption can be changed.
