How to specify signature version?

[TimurSadorov]

Hello! When I used package version 3.7.405.9, to enable signature version 4 I had to specify config AWSConfigsS3.UseSignatureVersion4 = true; but in version 4.0.6.13 this setting was removed, how to specify signature version 4 now?

Hi @TimurSadorov,

In AWS SDK for .NET v4, Signature Version 4 (SigV4) is now the default signing algorithm for S3 and other AWS services. The global AWSConfigsS3.UseSignatureVersion4 setting has been removed in v4 because it is no longer necessary.

For most use cases, you do not need to take any action to enable Signature Version 4.
