Lprs

Lprs is a local password manager designed to securely store and manage your passwords.

This is a fork of Lprs (https://github.com/TheAwiteb/lprs) with the aim to be an early demo for AmjadOS. See later how its being run

Installation

To install Lprs, you will need to have the Cargo package manager installed. If you do not have Cargo installed, you can install it by following the instructions here. Note the Minimum Supported Rust Version (MSRV) for Lprs is 1.70.0.

1. Install using cargo-install:

cargo install lprs --locked

This will enable the update notifications for Lprs. If you don't want to enable update notifications, you can install Lprs using:

cargo install lprs --locked --no-default-features

2. Run Lprs:

lprs --help

Uninstallation

cargo uninstall lprs

Usage

Lprs provides a command-line interface for managing your passwords. The following commands are available:

A local CLI password manager

Usage: lprs [OPTIONS] <COMMAND>

Commands:
  add     Add new password
  remove  Remove password
  list    List your password and search
  clean   Clean the password file
  edit    Edit the password content
  gen     Generate password
  export  Export the passwords
  import  Import passwords
  help    Print this message or the help of the given subcommand(s)

Options:
  -p, --passwords-file <PASSWORDS_FILE>
          The passwords json file, default: $HOME/.local/share/lprs/passwords.json
  -h, --help
          Print help
  -V, --version
          Print version

Example

lprs add -n "Gmail" -u "some@gmail.com" -p $(lprs gen 19 -u -l -s) -s "https://mail.google.com"

Result

This is the result when search for it

$ lprs list -e "mail" -p -s
Master Password: ***************
+-------+-------+----------------+---------------------+-------------------------+
| Index | Name  | Username       | Password            | Service                 |
+================================================================================+
| 31    | Gmail | some@gmail.com | >NC`q$%+Nno<y&<y]VB | https://mail.google.com |
+-------+-------+----------------+---------------------+-------------------------+

Backup

It is important to regularly backup your passwords to prevent data loss. Lprs does not provide an automatic backup feature. To backup your passwords, you can use the export command provided by Lprs. This command allows you to export your encrypted passwords to a json file, which you can then manually backup to a secure location.

Formats

The format of the exported file can be specified using the --format option. The following formats are supported:

• lprs: The default format used by Lprs. This format is encrypted and can be imported back into Lprs using the import command. This is the recommended format to use for backups as it is encrypted and can be imported back into Lprs.
• bit-warden: The format used by Bitwarden. This format is not encrypted and can be imported into Bitwarden. This format is useful if you want to switch to Bitwarden or another password manager that supports this format.

Running in AmjadOS

So, there are few changes made to the original code to make it run on AmjadOS. The changes are:

• Removed some dependancies (and related changes to the code):
  • comfy-table: because we don't have terminal window, so we just print the table as Vec<Vec<String>>
  • directories: because we don't have XDG directories, so we just use the / root directory, which only works for us. Thus, this will crash on windows and linux.
  • pretty_env_logger: not sure if it will work, but we don't need it.
  • scanpw: We don't have hidden password input, so we just use stdin to input the master password.
  • sha256: Too complex, replaced with better lhash crate.
  • url: Not needed.
• And changed random-pick which is used inside passwords to a modified version that doesn't use getrandom crate, from inside rand, since we don't have that, so replaced them to use a very basic "not random" small_rng from rand. Check the modifications in random-pick/src/lib.rs for example (same for random-number).

Ok, so next, is how we can build it. This is built for Amjad50/OS which of course is not available in rust.

Normally when developing a no-std project, we can use target.json files, but here this project uses std and requires libraries that use std as well. So the option here is to add our own custom target into rust.

Which is what I did here (notice this is not the default branch, so if u clone this make sure to checkout to that branch).

This is a fork of the rust compiler containing the target x86_64-unknown-amjad_os, so if you build the compiler. Like this

$ ./x.py build  -i --stage 1  --target x86_64-unknown-amjad_os

Then you can link it to rustup

$ rustup toolchain link amjad_os /path/to/rust/build/host/stage1

After that, you can come to this project, and run the build with the correct target and toolchain

$ cargo +amjad_os build --target x86_64-unknown-amjad_os

And with that, you will have an ELF file that you can use in AmjadOS.

You can do that by building AmjadOS, and adding the lprs elf to the filesystem folder along with passwords.json containing your passowrds (since at the time of writing there is no write support, only read). Then you can run read related commands of lprs and enjoy.
