@Immutable
@ThreadSafe
public interface AwsCrtS3V4aSigner
extends Signer, Presigner
```
Enables signing and presigning for S3 using Sigv4a (Asymmetric Sigv4) through an external API call to the AWS CRT (Common RunTime) library.
S3 signing specifics
For S3, the header "x-amz-sha256" must always be set for a request.
S3 signs the payload signing if:
1. there's a body and an insecure protocol (HTTP) is used.
2. explicitly asked to via configuration/interceptor.
Otherwise, the body hash value will be UNSIGNED-PAYLOAD.
See Amazon S3 Sigv4 documentation for more detailed information.
