 We have included cutils.rs, securemem.rs to make work the rpassword.rs file. Indeed, We thought that the password was well managed in this file and we have reused it. As sudo-rs does, rpassword.rs is from the rpassword project (License: Apache-2.0). We use it as a replacement of the rpassword project usage.
 
+This project was initiated by **IRIT** and sponsored by both **IRIT** and **Airbus PROTECT** through an industrial PhD during 2022 and 2025.
