Hi,

How can I create a SHA256 signature hash in D? Something similar 
to the PHP code below:

```php
openssl_sign($body, $signature, $secret, OPENSSL_ALGO_SHA256);
```

I've tried the code below without success:

```d
auto signature = 
body.representation.hmac!SHA256(secret.representation).toHexString!(LetterCase.lower).to!string;
```

```d
import std.digest.md;
import std.digest.sha;
import std.stdio;

void main()
{
     auto key = makeDigest!SHA256();
     key.put(cast(ubyte[])"çorba");
     auto result = key.finish();
     writeln(result.toHexString());
}
```

Thank you for your reply.

I have found that the issue is related to the 'Secret' variable. 
In fact, I possess a private key that needs to sign it for the 
JWT. How can I accomplish this? It appears that RSA encryption is 
required in this scenario.
