信任網

The Web of Trust describes the part of OpenPGP 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.

OpenKeychain的支援狀況

目前OpenKeychain對信任網只有基本程度的支援。這是一件大工程，有任何進展將隨時發佈。

信任模式

信用評價基於一個前提：所有帶有密鑰的金鑰都是可以信任的。所有可信任金鑰簽署過的公鑰，會在清單裡被標上一個綠圓點。目前並不支援指定其他公鑰的信任等級。

金鑰認證

金鑰認證是支援的，而且每個身份可以個別進行認證。然而，目前並不支援指定簽署的信任等級與建立本機或其他形式的認證。
