How to upload a file from ESP32 to AWS S3 bucket.

[brahmajit]

I'm trying to upload plaintext file from my ESP32 to S3 bucket. I've got till using a GET request to add query parameter after the REST API link. Now I want to upload a file using PUT a put request. Does anyone knows how to do this? Just using a PUT request is not working as one needs to sign the file to upload.

Thanks
