### Installing ipcrypt-js Library (Shell)

Source: https://github.com/jedisct1/ipcrypt-js/blob/main/README.md

Provides commands to install the `ipcrypt-js` library using popular JavaScript package managers, npm and Bun. Requires a Node.js or Bun environment with the respective package manager installed.

```sh
# Using npm (Node.js)
npm install ipcrypt

# Using Bun
bun add ipcrypt
```

### Implementing Deterministic Encryption (JavaScript)

Source: https://github.com/jedisct1/ipcrypt-js/blob/main/README.md

Shows how to use the `deterministic` module from `ipcrypt` to encrypt and decrypt an IP address. Requires importing the module, generating a 16-byte key, and using the `encrypt` and `decrypt` functions.

```javascript
import { deterministic } from 'ipcrypt';

// Create a 16-byte key
const key = new Uint8Array(16);
crypto.getRandomValues(key);

// Encrypt an IP address
const encrypted = deterministic.encrypt('192.168.1.1', key);
console.log(encrypted); // Encrypted IP address

// Decrypt the IP address
const decrypted = deterministic.decrypt(encrypted, key);
console.log(decrypted); // '192.168.1.1'
```

--------------------------------

### Using IP Conversion Utility Functions (JavaScript)

Source: https://github.com/jedisct1/ipcrypt-js/blob/main/README.md

Shows how to use the `utils` module to convert IP address strings to byte arrays (`Uint8Array`) and vice-versa. Requires importing the `utils` module from the library.

```javascript
import { utils } from 'ipcrypt';

// Convert IP address to bytes
const bytes = utils.ipToBytes('192.168.1.1');
console.log(bytes); // Uint8Array

// Convert bytes back to IP address
const ip = utils.bytesToIp(bytes);
console.log(ip); // '192.168.1.1'
```

--------------------------------

### Implementing Non-Deterministic Encryption (JavaScript)

Source: https://github.com/jedisct1/ipcrypt-js/blob/main/README.md

Demonstrates using the `nonDeterministic` module for encryption and decryption. Requires importing the module, generating a 16-byte key and an 8-byte tweak, and using the `encrypt` and `decrypt` methods.

```javascript
import { nonDeterministic } from 'ipcrypt';

// Create a 16-byte key and 8-byte tweak
const key = new Uint8Array(16);
const tweak = new Uint8Array(8);
crypto.getRandomValues(key);
crypto.getRandomValues(tweak);

// Encrypt an IP address
const encrypted = nonDeterministic.encrypt('192.168.1.1', key, tweak);
console.log(encrypted); // Uint8Array containing encrypted data

// Decrypt the IP address
const decrypted = nonDeterministic.decrypt(encrypted, key);
console.log(decrypted); // '192.168.1.1'
```

--------------------------------

### Implementing Extended Non-Deterministic Encryption (JavaScript)

Source: https://github.com/jedisct1/ipcrypt-js/blob/main/README.md

Illustrates the usage of the `nonDeterministicExtended` module for encryption and decryption with larger keys and tweaks. Requires importing the module and generating 32-byte key and 16-byte tweak values.

```javascript
import { nonDeterministicExtended } from 'ipcrypt';

// Create a 32-byte key and 16-byte tweak
const key = new Uint8Array(32);
const tweak = new Uint8Array(16);
crypto.getRandomValues(key);
crypto.getRandomValues(tweak);

// Encrypt an IP address
const encrypted = nonDeterministicExtended.encrypt('192.168.1.1', key, tweak);
console.log(encrypted); // Uint8Array containing encrypted data

// Decrypt the IP address
const decrypted = nonDeterministicExtended.decrypt(encrypted, key);
console.log(decrypted); // '192.168.1.1'
```
