Structures

This structure represents padded plaintext. Blocks are acutally a byte array which is a multiple of a given block size.

A ciphertext is an ecrypted message. In contrast to EncryptedData it only contains the encrypted message, while EncryptedData might contain other information as well, such as a message authentication code et cetera.

This class represents hashed passwords. They can be used to store passwords for the purpose of authenticating users. Passwords should not be stored as plaintext values to avoid compromise if they get in the wrong hands.

Example

let password = Password("Correct Horse Battery Staple")!
let hashedPassword = password.hash()!

// Store `hashedPassword.string` to database.

// If a user wants to authenticate, just read it from the database and
// verify it against the password given by the user.
if hashedPassword.isVerified(by: password) {
    // The user is authenticated successfully.
}

This can be used to securely generate random data.

A wrapper for libsodium that on one hand offers convenient access to the libsodium bindings and on the other hand assures that libsodium was initialized before actually invoking methods.
