CoSi Standalone Binary Release

May 24, 2016  

Dear all,

with the acceptance of the paper “Keeping Authorities ‘Honest or Bust’ with Decentralized Witness Cosigning” at IEEE S&P 2016, we updated our code to make it even more easy to integrate it with your projects.

For details on how to use the CoSi-application, go to .

The code is now based on our latest cothority-framework and can be called from your program to generate a collective signature of a file. The same code also verifies the signature or can be used as a server if you want to run your own cothority-group.

There are two proposals to include the collective signing and verification in open-source-libraries: - Go crypto library: - C libsodium: Both forks can be used to verify the signatures created by our latest CoSi-release.

If you have questions or remarks, feel free to contact us here or open issues on .

Yours, the DeDiS-team
