How-to guides¶

Each page solves one problem for someone who already knows what they are trying to do. If you are meeting the crate for the first time, start with the tutorial instead.

Add a credential to your tool's config	Expose a credential an operator can configure four different ways.
Store a secret in the OS keychain	Write a secret to the platform keychain and read it back.
Supply credentials in CI	Get a pipeline resolving credentials without tripping the literal refusal.
Test code that resolves credentials	Write tests that never touch a real keychain.
