This package contains optional dependency @aws-sdk/signature-v4-crt.
You need to install this package explicitly to sign an un-regional request using SigV4a algorithm. The package contains
Node.js native implementation which requires building at installation. The installed package MAY NOT work if the
instance building the package runs a different operating system than the instance running the application.
The @aws-sdk/signature-v4-crt is only supported in Node.js currently because it depends on a native dependency.
Please refer to this issue for more information.
This package provides a SigV4-compatible request signer that wraps a pure-JS SigV4 signer
(@aws-sdk/signature-v4) for regional requests, and attempts to
call a native implementation of SigV4a signer(@aws-sdk/signature-v4-crt)
it the request is not regional.
An un-regional request is identified by the signingRegion parameter. A region is un-regional if the signingRegion
parameter is set to *.
