Verifiable Source

We understand the importance of being able to verify that the cryptography you're using is correct and not maliciously or accidentally sharing your secrets with others. Here you can find source archives for each release version of Semaphor.

There are terms and conditions around the source we're distributing here, and you can find those under the SpiderOak Semaphor App License.

Finally, we're happy to be using lots of free and open source software (FOSS) as part of Semaphor. We have the required license notices at our Third Party FOSS license page.

While reviewing the source code, it may be helpful to cross-reference the Semaphor Encryption white paper.
