InternalStaticsigv4aSign the provided request for immediate dispatch.
Sign with alternate credentials to the ones provided in the constructor. Note: This is only supported for SigV4a when using the CRT implementation.
Presign a request. Note: This is only supported for SigV4a when using the CRT implementation.
A SigV4-compatible signer for S3 service. In order to support SigV4a algorithm according to the operation input dynamically, the signer wraps native module SigV4a signer and JS SigV4 signer. It signs the request with SigV4a algorithm if the request needs to be signed with
*region. Otherwise, it signs the request with normal SigV4 signer.
