The Virtual Ideal Functionality Framework (VIFF) is a framework for creating efficient and secure multi-party computations (SMPC). Players, who do not trust each other, participate in a joint computation based on their private inputs.
The computation is done using a cryptographic protocol which
... [More] allows them to obtain a correct answer without revealing their inputs. Operations supported include addition, multiplication, and comparison, all with Shamir secret shared outputs. [Less]
Tomb is a system to make strong encryption easy for everyday use. A tomb is like a locked folder that can be safely transported and hidden in a filesystem. Its keys can be kept separate; for example, you can keep the tomb on your computer and its key on a USB stick or a remote SSH shell.
Tomb is
... [More] written in code that is easy to review and links shared components: it consists of a ZShell script and desktop integration apps; it uses standard GNU tools and the cryptographic API of the Linux kernel (dm-crypt) via cryptsetup. [Less]
