revoker

A revoker is a term that can refer to several concepts depending on the context. In legal and contractual settings, a revoker is an entity or individual that exercises the right to revoke, cancel, or withdraw something previously granted or offered. This could involve revoking a power of attorney, a will, a license, a permit, or an offer made in a contract. The ability to revoke is often stipulated within the terms of the original agreement or by law. The act of revocation typically renders the original grant or offer null and void.

In a more technical or computing context, a revoker might be associated with systems that manage digital certificates or permissions. For example, a Certificate Revocation List (CRL) is a list of digital certificates that have been revoked by the issuing Certificate Authority (CA) before their scheduled expiration date. A revoker in this scenario would be the authority or process responsible for identifying and listing these invalid certificates. Similarly, in software or access control systems, a revoker could be a function or user role that has the authority to remove or disable previously granted access or privileges. The specific implementation and implications of a revoker are highly dependent on the system or framework in which it operates.
