Crate rust_ev_crypto_primitives

source
Expand description

Crate implementing the cryptographic functions for E-Voting

It is based on the specifications of Swiss Post, according to the following document version: Crypo-primitives, version 1.4.1

The crate reduces actually at the necessary functions for the Verifier. The crate is grouped in modules releated to themes, like the specifications

The module crate::basic_crypto_functions contains a wrapper to openssl. Details about installation and functionalities can be found on the crate openssl.

The crate ist based on rug that is strongly performant, but GMP must be installed for compilation. See the requirements and installation path in the crate documentation rug

If a method should return an error, then each error type is specified per module and is transparent to the user of the crate.

§Features

Following feature is possible:

  • “checks”: The library will perform checks of the input data, according to the specifications of Swiss Post. This reduces the performance. If the checks are performed during the usage of the crate, it is recommended, not to activate the feature
