Module: Ironclad::Cache

Defined in:
lib/ironclad/cache.rb,
lib/ironclad/cache/null.rb,
lib/ironclad/cache/keyctl.rb,
lib/ironclad/cache/keychain.rb

Overview

Selects the OS keystore backend for the current platform. A backend responds to #read(name), returning the cached string or nil, and #write(name, key), returning true when the key is cached and false when it is not. A backend with nowhere to store keys reports true: nothing to do is not a failure.
