<p>The Web of Trust describes the part of PGP which deals with creation and bookkeeping of certifications. It provides mechanisms to help the user keep track of who a public key belongs to, and share this information with others; To ensure the privacy of encrypted communication, it is essential to know that the public key you encrypt to belongs to the person you think it does.</p>
<p>Trust evaluation is based on the simple assumption that all keys which have secret keys available are trusted. Public keys which contain at least one user id certified by a trusted key will be marked with a green dot in the key listings. It is not (yet) possible to specify trust levels for certificates of other known public keys.</p>
<p>Podpora pro certifikaci klíčů je dostupná a uživatelská ID mohou být certifikována jednotlivě. Ještě není možné určovat úroveň důvěryhodnosti nebo vytvářet lokální a jiné speciální typy certifikátů.</p>
