Description:
The goal is to rewrite a part of the Hashicorp vault in Rust.
It should be compatible with the current version of the vault an its clients.
Therefore a vault client written in go is used to perform tests.
During this project only a small part will be implemented. 
It will be further developed as an open-source project.
Achieved features include:

- Design of the architecture 
- Implementation of dynamic routing to allow for exchangeable secret engines
- Basic kv-store
