- **JavaScript**: The `atob()` function decodes a Base64 encoded string.

- **Python**: The `base64.b64encode()` function encodes a string into Base64.

- **PHP**: The `base64_decode()` function decodes Base64 encoded data.

- **Java**: The `Base64.getEncoder().encodeToString()` encodes a string to Base64.

- **C#**: The `Convert.ToBase64String()` method encodes a string into a Base64 string.

- **Ruby**: The `Base64.encode64()` method encodes a string into Base64.

- **MySQL**: The `TO_BASE64()` function encodes a string to Base64.

- **PostgreSQL**: The `encode()` function with 'base64' parameter encodes a string to Base64.

- **Linux CLI**: The `base64` command, alongside the `echo -n` command, encodes a string into Base64.
