Struct IpcryptNd 

pub struct IpcryptNd { /* private fields */ }

A structure representing the IPCrypt context for non-deterministic mode.

This struct provides methods for encrypting and decrypting IP addresses using KIASU-BC mode with an 8-byte tweak. The key is 16 bytes (one AES-128 key).

Implementations

impl IpcryptNd

pub const KEY_BYTES: usize = 16usize

The number of bytes required for the encryption key.

pub const TWEAK_BYTES: usize = 8usize

The number of bytes required for the tweak.

pub const NDIP_BYTES: usize = 24usize

The number of bytes in the non-deterministic mode output (8-byte tweak + 16-byte ciphertext).

pub fn generate_key() -> [u8; 16]

Generates a new random key for encryption.

pub fn new(key: [u8; 16]) -> Self

Creates a new IpcryptNd instance with the given key.

Arguments

• key - A 16-byte array containing the encryption key.

pub fn new_random() -> Self

Creates a new IpcryptNd instance with a random key.

pub fn generate_tweak() -> [u8; 8]

Generates a random tweak.

pub fn encrypt_ipaddr(&self, ip: IpAddr, tweak: Option<[u8; 8]>) -> [u8; 24]

Encrypts an IP address using non-deterministic mode with KIASU-BC.

Arguments

• ip - The IP address to encrypt
• tweak - Optional tweak to use. If None, a random tweak will be generated.

Returns

A 24-byte array containing the concatenation of the 8-byte tweak and the 16-byte encrypted IP address.

pub fn decrypt_ipaddr(&self, encrypted: &[u8; 24]) -> IpAddr

Decrypts an IP address that was encrypted using non-deterministic mode with KIASU-BC.

Arguments

• encrypted - A 24-byte array containing the concatenation of the 8-byte tweak and 16-byte ciphertext

Returns

The decrypted IP address
