    ```
  </Tab>

## Basic Example

<Tabs items={['Python', 'Go', 'Rust', 'Node.js']}>
  <Tab>
    ```python
    from luxfhe import Client, Server

    # Client encrypts
    client = Client()
    a = client.encrypt(42)
    b = client.encrypt(8)

    # Server computes
    server = Server(client.evaluation_key)
    result = server.add(a, b)

    # Client decrypts
    print(client.decrypt(result))  # 50
    ```
  </Tab>
  <Tab>
    ```go
    import "github.com/luxfi/fhe"

    client, _ := fhe.NewClient()
    server, _ := fhe.NewServer(client.EvaluationKey())

    a, _ := client.Encrypt(42)
    b, _ := client.Encrypt(8)

    result, _ := server.Add(a, b)

    fmt.Println(client.Decrypt(result)) // 50
    ```
  </Tab>
  <Tab>
    ```rust
    use luxfhe::{Client, Server};

    let client = Client::new()?;
    let server = Server::new(client.evaluation_key())?;

    let a = client.encrypt(42u64)?;
    let b = client.encrypt(8u64)?;

    let result = server.add(&a, &b)?;

    println!("{}", client.decrypt::<u64>(&result)?); // 50
    ```
  </Tab>
  <Tab>
    ```typescript
    import { Client, Server } from '@luxfhe/core';

    const client = await Client.create();
    const server = await Server.create(client.evaluationKey);

    const a = await client.encrypt(42n);
    const b = await client.encrypt(8n);

    const result = await server.add(a, b);

    console.log(await client.decrypt(result)); // 50n
    ```
