First, I would like to express my gratitude for the code in repo:

https://github.com/WhisperSystems/curve25519-java

Great work!

I work for ASSA ABLOY AB, the world's largest lock manufacturer in the world. We are starting
(in a very small scale) to contribute to the open source world. We recently released a secure channel
implementation called Salt Channel. See: https://github.com/assaabloy-ppi/salt-channel/.

Anyway, Whisper's Java code is impressive. However, we cannot use it because of the GPL license.
Would you consider releasing WhisperSystems/curve25519-java with a more business-friendly license?
Perhaps MIT or LGPL. It is a low-level library... and based on the public domain work by Bernstein.
Of course, it is not my thing to have opinion on what license you use for this. I would just like to make
you aware of our needs.

If WhisperSystems/curve25519-java would have a MIT/LGPL license, it would be easier for
us to contribute more to the open source world.

Thanks, Frans

Would you consider releasing your product's source code under a license that respects the freedom of your product's users?

I, for one, appreciate that Signal and related libraries are published under a copyleft license and that OWS is willing to enforce it.

Cheers,
Stephen

Personally, I would like to see more open source code in electronic
locks and access control in general. And my personal view is that
it would be very interesting to see an electronic open source
lock (open source hardware too) on the market. I am not
at liberty to say whether ASSA ABLOY considers releasing our
product's source code under an open source licence.
Or rather: it depends. The curve25519 library is a low-level library
that could be used for *both* open source projects and proprietary
solutions. We actual *do* release some of our code as open source
already (see link in original post).

I understand the reasons why the Signal applications are copyleft.
Actually, I like it. However, the lower-level libraries, such as
the Curve25519 implementation could still be LGPL (or similar).

Hi Frans,

Just putting aside the debate about licenses, please keep in mind this is a
public discussion forum, and most of us (including me) are not affiliated
with Open Whisper Systems, so if you want to discuss this possibility with
the people who actually could decide whether or not to make such a change,
you may want to reach out to OWS directly (assuming nobody from there has
responded to you privately already)

Thanks,
Laurence

If you want it for a close source project, then I suggest you contact
them privately to ask them to sell you a suitable closed source
license.

Right now, there is a trend towards releasing crypto under more
permissive licenses, but that's partially due to Apple's obnoxious app
store polices being one primary reason.* Java cannot be used in an iOS
app anyways, so that reason does not apply here.

Jeff

* I'm hoping the FSF creates an App Store compatible GPL that works by
the developer assuming Apple's GPL obligation and only granting Apple
the right to distribute a reproducible build.
