I try to save data in amazon s3 by using Svens  package 'Zinc-AWS'.

I created a bucket in s3 and can read it from pharo.

But when I want to save data from pharo the requests response is

<?xml version="1.0" encoding="UTF-8"?>

<Error><Code>InvalidRequest</Code><Message>The authorization mechanism you have provided is not supported. Please use AWS4-HMAC-SHA256.</Message><RequestId>....</RequestId><HostId>....</HostId></Error>

I see that ZnAWSS3RequestSignatureTool uses (HMAC on: SHA1 new).

Here I have problems to go further and do not know if/how I have to change the authorization mechanism.

Or is the ZnAWSS3RequestSignatureTool old?

Yes

Anyone having a hint or working code snippet for me?

Sven could you perhaps have a look?

The code has to be updated, but I do not have time for that.
It would be nice if somebody else could have a look.
