In PGP, normal users can issue certificates to each other, forming a web of trust, and fingerprints are often used to assist in this process (e.g., at key-signing parties). In systems such as CGA or SFS and most cryptographic peer-to-peer networks , fingerprints are embedded into pre-existing address and name formats (such as IPv6 addresses ...
How to compose a new message. Click "New message" at the top of the folder list. Start typing the name of the addressee in the "To" field. Outlook will display a dropdown menu of complete email ...
The Subject Information Access extension can carry a URI to point to certificate repositories and timestamping services.

There are two main reasons ...
