Support of Signature Version 4 for mini_s3 and mainly for Chef11.

[alokdnb]

We were trying to create a new chef environment and use the Frankfurt as the s3 bucket location. what we have noticed is that we are getting error about the signature version that we have used is not supported? can you confirm if we have any plans to use the Signature Version 4 for the mini_s3 API. We are currently using the CHEF 11.

I am bumping this thread to check if any developer is still looking into it.

This is going to need to be done soon; June 24, 2019 is the EoL date for V2 signing (https://forums.aws.amazon.com/ann.jspa?annID=5816)

This library no longer functions due to this issue.
