## Syntax

```
SHA256(stringToConvert, charSet)
```

The `SHA256()` function has two parameters:

- `stringToConvert` (string): Required. The string to encode.
- `charSet` (string): The character set to use for encoding. Accepted values are `UTF-8` and `UTF-16`. The default value is `UTF-8`.

## Usage

To use this function, pass it a string.

```
%%=SHA256("This is a string of text.")=%%
```

The function outputs a SHA-2 hash of the provided string: `99d1f7b534824f35dffa18c3b728ecb00c4585ba9d7c9b26205424f8f28eff8e`

You can also generate the hash using UTF-16 encoding, as in this example.

```
%%=SHA256("This is a string of text.", "UTF-16")=%%
```

The function outputs a SHA-2 hash that uses UTF-16 encoding: `84b87f1ae08610f97a0bb6c228dd2289a54203c23ee2af17d617a1c1b4a0ab1a`
