PassVault is a vault for your passwords.
The idea behind PassVault is that the passwords are e2e encrypted using pairs of keys. The encryption/decryption process is done in the frontend, so only you can read your passwords as long as you keep your private key private. ;-)
This piece should be used as the central storage backend on a server. Any Server should be able to do it, as long as it supports running an application compiled to Java Bytecode.
As mentioned above this software is compiled to Java Bytecode. It is implemented in Kotlin and uses PostgreSQL as a database backend. You only need a running database and gradle at least in version 4.5 installed on your machine.
First make sure you run all the database migrations in your database. After that be sure to
set the SODIUM_LIBRARY_PATH environment variable to the right value. When finished with that
you can run gradle run in your terminal.
