signed_id_verifier()

public

The verifier instance that all signed ids are generated and verified from. By default, it’ll be initialized with the class-level signed_id_verifier_secret, which within Rails comes from {Rails.application.key_generator}[rdoc-ref:Rails::Application#key_generator]. By default, it’s SHA256 for the digest and JSON for the serialization.
