OpenPGP is the most widely used email encryption standard. It is defined by the OpenPGP Working Group of the Internet Engineering Task Force (IETF) as a Proposed Standard in RFC 4880. OpenPGP was originally derived from the PGP software, created by Phil Zimmermann.
Email encryption
Although OpenPGP’s main purpose is end-to-end encrypted email communication, it is also utilized for encrypted messaging and other use cases such as password managers.
For all operating systems
OpenPGP is available for all major platforms, such as Windows, Mac OS, GNU/Linux, Android, and iOS.
Standing the test of time
OpenPGP was standardized in 1997 and since then continuously improved. As far as we know, intelligence organizations aren’t able to break it.
Please refer to the Release Notes of each build for more details. This document aims to clarify information for compatibility and Symantec Encryption Desktop.
Applies To
Mac OS X and Symantec Encryption Desktop :
TIP: For more information on System Requirements for Symantec Encryption Desktop, please see KB article TECH224417.
Caution: Symantec Encryption Desktop 10.3.2 is not currently supported in the following scenario, however Symantec is currently looking into these scenarios as future features:
- Mac systems which have 4K Native drives. For more information, see article TECH200098.
TIP For SEE 11: For Mac OS X System Requirements for Symantec Endpoint Encryption 11, see article INFO3170. As a general rule of thumb, if Symantec Endpoint Encryption 11.1.2 has been certified for Mac OS X 10.12, it is also certified for 10.12 subsequent releases. It is not necessary to wait for a newer version of SEE 11.1.2 to use on a newer version of Mac OS X 10.12 as long as the version supports the base release of Mac OS X. For example, SEE 11.1.2 supports Mac OS X 10.12, so this can be used to install on Mac OS X 10.12.5.
______________________________________________________________________________________________________________________________________________________
The versions of Symantec Encryption Desktop and versions of Mac OS X contained in this article have been officially tested and certified. If versions of Mac OS X are not listed on this article, the version is not officially tested and is therefore not officially supported. It is not recommended to install on versions of Mac OS X unless stated on this article.

Failure to do so could result in data that cannot be recovered. This issue will be resolved in a future release of the product. [3653114]. For information on how to disable CoreStorage, see article HOWTO109622.
NOTE: Mac OS X 10.10.1 was not compatible with any Symantec Encryption Desktop products prior to 10.3.2 MP7. If any version prior to Symantec Encryption Desktop 10.3.2 MP7 was installed on Mac OS X 10.10.1 or 10.10.2, first uninstall these versions before installing Symantec Encryption Desktop 10.3.2 MP7 or above.
