 The version info is using gitinfo2. To use the setup one has to run the `papers/tex/gitinfo2.sh` script. In local copies it's also possible to add this as a post-checkout or post-commit hook to keep it automatically up to date.
 
 The version information in the footer automatically includes a “draft”. This can be removed by tagging a release version using `\jobname-release`, e.h. `whitepaper-release` for the `whitepaper.md` file.

 Rosenpass inherits most security properties from Post-Quantum WireGuard (PQWG). The security properties mentioned here are covered by the symbolic analysis in the Rosenpass repository. 
 
 ## Secrecy
-Three key encapsulations using the keypairs `sski`/`spki`, `sskr`/`spkr`, and `eski`/`epki` provide secrecy (see Section \ref{variables} for an introduction of the variables). Their respective ciphertexts are called `scti`, `sctr`, and `ectr` and the resulting keys are called `spti`, `sptr`, `epti`. A single secure encapsulation is sufficient to provide secrecy. We use two different KEMs (Key Encapsulation Methods; see section \ref{skem}): Kyber and Classic McEliece.

   These keys can then be passed to various services such as wireguard or other vpn services
