Go S3 Signature v2 Helper

Go-S3-Sig-v2 is a fast and lightweight library for creating requests that implement AWS' S3 v2 signature specification, which is particularly useful for S3-compatible object storage systems like Pithos that don't support AWS v4 signatures. It is a fork of smartystreets/go-aws-auth with all other signature types removed (as they are in aws-sdk-go and aren't needed for whats-this) and some performance improvements.

This wouldn't be a thing if aws-sdk-go had it implemented to begin with.

Using

go get it:

$ go get github.com/whats-this/go-s3-sig-v2

Then use it:

import "github.com/whats-this/go-s3-sig-v2"

credentials := s3sigv2.S3CredentialsPair{
	AccessKeyID:     "",
	SecretAccessKey: ""
}
credentials.SignHTTPRequest(req)

The library does not check environment variables or anywhere else for credentials, it is up to you to manage where the credentials come from and expiration stuff.

Remember to be careful hard-coding credentials into your application if the code is committed to source control.
