Hello
I have a problem when I use the projeqtor API...
The problem is with the data encryption.
I use an external site to generate my encrypted data

In the link above, you will see that I use a site to encrypt my data, using my API key.
I use AES-CTR 128

But using postman to simulate the request, I get the error :
    "message": ""'data' is not correctly encoded for method POST. Request for correct API KEY""
 See the link below

If I use your AesCtr::encrypt function, it works, but unfortunately, I can only use it in php, and my API will be called by many other languages...

Do you know where the problem can come from? 
It seems to me that I have done everything right...

Thanks a lot
