Sequoia PGP is owned by the [p≡p foundation] and licensed under the terms of the LGPLv2+. [p≡p foundation]: https://pep.foundation/ To finance its mission, privacy by default, the [p≡p foundation] allows third parties (currently only [p≡p security]) to relicense its software. Consistent with the rules of a foundation, the money collected by the foundation in this manner is fully reinvested in the foundation's mission, which includes further development of Sequoia PGP. [p≡p security]: https://www.pep.security/ To do this, the [p≡p foundation] needs permission from all contributors to relicense their changes. In return, the [p≡p foundation] guarantees that *all* releases of Sequoia PGP (and any other software it owns) will also be released under a GNU-approved license. That is, even if Foo Corp is granted a license to use Sequoia PGP in a proprietary product, the exact code that Foo Corp uses will also be licensed under a GNU-approved license. If you want to contribute to Sequoia PGP, and you agree to the above, please sign the [p≡p foundation]'s [CLA]. This is an electronic assignment; no paper work is required. You'll need to provide a valid email address. After clicking on a link to verify your email address, you'll receive a second email, which contains the contract between you and the [p≡p foundation].
