Unable to get Presigned Object URL Using AWS SDK f

问题:

I am currently working with S3 and need to extract an S3 resource which has a timeout for streaming, so that the client cannot use the URL after a specific amount of time.

1. I have already used some code provided in the documentation for "Presigned Object URL Using AWS SDK for .NET".
2. The code will provide a temporary URL which can be used to download an S3 resource by anyone...but within a specific time limit.
3. I have also used the Amazon S3 Explorer for Visual Studio, but it doesn't support URL generation for resources embedded with AWSKMS key.
4. Also tried deleting the KMS Key for the S3 folder, but that is throwing an error.

If there is a possible link for deleting KMS keys can you also include it in your answers.

            }

SignatureDoesNotMatch The request signature we calculated does not match the signature you provided. Check your key and signing method. AKIA347A6YXQ3XM4JQ7A

This is the error that I am getting when I am trying to access the generated URL and that is probably because the AWSKMS authentication is having some issue.
