Status of this Memo

IESG Note

This document defines many tag values, yet it doesn't describe a mechanism for adding new tags (for new features). Traditionally the Internet Assigned Numbers Authority (IANA) handles the allocation of new values for future expansion and RFCs usually define the procedure to be used by the IANA. However, there are subtle (and not so subtle) interactions that may occur in this protocol between new features and existing features which result in a significant reduction in over all security. Therefore, this document does not define an extension procedure. Instead requests to define new tag values (say for new encryption algorithms for example) should be forwarded to the IESG Security Area Directors for consideration or forwarding to the appropriate IETF Working Group for consideration.

Abstract

This document is maintained in order to publish all necessary information needed to develop interoperable applications based on the OpenPGP format. It is not a step-by-step cookbook for writing an application. It describes only the format and methods needed to read, check, generate, and write conforming packets crossing any network. It does not deal with storage and implementation questions. It does, however, discuss implementation issues necessary to avoid security flaws.

Open-PGP software uses a combination of strong public-key and symmetric cryptography to provide security services for electronic communications and data storage. These services include confidentiality, key management, authentication, and digital signatures. This document specifies the message formats used in OpenPGP.
