signer defines:\n 1. Trust distribution: how trust (CA bundles) are distributed.\n 2. Permitted subjects: and behavior when a disallowed subject is requested.\n 3. Required, permitted, or forbidden x509 extensions in the request (including whether subjectAltNames are allowed, which types, restrictions on allowed values) and behavior when a disallowed extension is requested.\n 4. Required, permitted, or forbidden key usages / extended key usages.\n 5. Expiration/certificate lifetime: whether it is fixed...
