The mfsecretsaws vault provider is authenticated using a credentials key pair containing a key ID and key. Generate a credentials key pair for the AWS vault and specify them in the configuration file. The key pair will take the form of hashes.
A geographical regional endpoint should also be configured. Micro Focus recommends that you specify the region closest to the systems current physical location.
For example:
region=us-east-2 access_key=MY_AWS_ACCESS_KEY secret_access_key=MY_AWS_ACCESS_KEY_VALUE
