Storing passwords and secret configuration is a challenge for an application. Ada Keystore is a library that stores arbitrary content by encrypting them in secure keystore (AES-256, HMAC-256). The talk presents the project and shows how to use the Ada Keystore library to get or store secret information in a secure manner. The presentation explains how the Ada features such as types, protected types, tasks, pre/post conditions have helped during the development of this project.
