vault_aws_auth

These are python 2 and 3 snippets showing how to generate headers to authenticate with HashiCorp's Vault using the AWS authentication method. There's also a Ruby implementation which uses version 3 of the AWS SDK for Ruby.

The python scripts look for credentials in the default boto3 locations; if you need to supply custom credentials (such as from an AssumeRole call), you would use the botocore.session.set_credentials method before calling create_client.
