Does this do what you want?


```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.

SHA256 Signature

[Vahid via Digitalmars-d-learn]

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;

```

Google Auth API

[Vahid via Digitalmars-d-learn]

Hi,

Has anyone here had experience implementing the Google Auth 
Library in DLang? Specifically, I am looking for guidance on 
handling OAuth 2.0 using JWT. Are there any current libraries 
available for this purpose?

If you're using D's standard library, you would need to replace 
the space
with a T so that the time format was ISO extended. Then you can 
use
DateTime.fromISOEXtString() in std.datetim.date to get a 
DateTime. You can
then add a duration to the DateTime to change its value - e.g. 
using
hours(2) (or dur!"hours"(2) for the generic version). Then if 
you want
a string again, toISOExtString will convert the DateTime to the 
ISO extended
format, and if you want a space instead of a T, then just 
replace the T with

a space in the string. E.G.

Thank you. It works very well.

Convert String to Date and Add ±N Hours

[Vahid via Digitalmars-d-learn]

Hi,

I have a date string with the format of "2023-11-04 23:10:20". I 
want to convert this string to Date object and also, add ±N hours 
to it. For example:


`"2023-11-04 23:10:20" + "+2:00" = "2023-11-05 01:10:20"`
`"2023-11-04 23:10:20" + "-2:30" = "2023-11-05 20:40:20"`

How can I do this?

HTTP Post Body Parameters

[Vahid via Digitalmars-d-learn]

Hi,

I want to submit a request to server with "x-www-form-urlencoded" 
header. This is the simplified version of my code:



auto http = HTTP("https://myurl.com/api;);
http.addRequestHeader("Content-Type", 
"application/x-www-form-urlencoded");

http.addRequestHeader("Authorization", "SID:TOKEN");

auto params = "Param1=one=two";
http.setPostData(params, "application/x-www-form-urlencoded");

http.onReceive = (ubyte[] response)
{
return cast(string) response;
};
http.perform();

This doesn't work as the server not receiving the parameters as 
post body. How can I send parameters as post body (or form data)?


This is the RAW CURL version that I want to write using D:

curl -X POST "https://myurl.com/api; \
--data-urlencode "Param1=one" \
--data-urlencode "Param2=two" \
-u SID:TOKEN
