Need to update the signature version for authentication? about django-amazon-ses

[hectcastro]

This is my understanding as well. Inspecting the API calls in DEBUG mode reveals that Signature Version 4 is being used for interactions with the region I've targeted (us-east-1).

See also: https://docs.aws.amazon.com/AmazonS3/latest/dev/UsingAWSSDK.html#specify-signature-version

For all AWS Regions, AWS SDKs use Signature Version 4 by default to authenticate requests. When using AWS SDKs that were released before May 2016, you might be required to request Signature Version 4, as shown in the following table.

Going to close this for now, but please reopen if see any contrary evidence.

Seems like boto3 handles this itself?

Excerpts from AWS signature version 4 signing process,

If you are using one of the AWS SDKs (including the SDK for C++, SDK for Go, SDK for Java, AWS SDK for JavaScript, AWS SDK for .NET, SDK for PHP, SDK for Python (Boto 3), or SDK for Ruby), you do not have to manually perform the steps of deriving a signing key and adding authentication information to a request. The SDKs perform this work for you. You need to manually sign requests only if you are directly making HTTP or HTTPS requests.
