notations for OpenPGP signatures


aim of this website

The motivation to create this site is to promote the uniform usage of signature notations and provide a namespace for them. Furthermore popular notations from other namespaces shall be documented here.

If you have an idea for a new uniform notation then you can submit it here. If a notation turns out to be widely used then it might be suggested for the official uniform namespace, the IETF namespace.

What are the requirements for a key certification useful to others?

How is this to be achieved?

The OpenPGP standard provides all that is necessary: All these pieces of information can be put in certification notations. What we need are standards for expressing this information: human readable in the beginning, machine readable after official (IETF) standardization so that really usable trust models can be built on top of this by OpenPGP applications.
