App Lingo¶
This is a place to explore the language used to describe the various pieces of OpenPGP. Each app seems to have similar but often conflicting lingo.

- keyring - "In your public keyring you hold public keys of people you want to send encrypted documents. The keyring also supports you to judge the trust in other keys which ultimately leads to trust identification for signatures you encounter in files, emails and other documents." (source)
- owner trust - "This value describes your opinion about the other ones ability to correctly sign other keys. Your personal trust in the owner of a public key varies from full trust (thumb up) over marginal trust (thumb horizontal) to no trust (thumb down). If you have no opinion about the person, you can leave the ownertrust unknown." (source)
