#Get a value from nested maps

The get_in function can be used to retrieve a nested value in nested maps using a list of keys.

nested_map = %{ name: %{ first_name: "blackode"} }     #Example of Nested Map
first_name = get_in(nested_map, [:name, :first_name])  # Retrieving the Key

# Returns nil for missing value 
nil = get_in(nested, [:name, :last_name])              # returns nil when key is not present

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.
