Password generator & vault #23

CLI Vault Tool Implementation

Overview

I've implemented a CLI tool for generating and securely storing (by encrypting) service credentials. The tool provides only the most basic functional, but I have some further to expand the project.

Features

• Add new entries with customizable parameters
• Delete existing entries
• List entries with:
  • Exact service name matching
  • Regex pattern matching
• Secure password/pin generation with cryptography module
• All the credentials are decrypted before storing in JSON file

Implementation Structure

File	Responsibility
main.py	CLI interface and command processing
vault.py	Core vault logic and storage
password.py	Secure password/pin generation

Usage Examples

Adding Entries

python3 vault.py add --service GitHub --username rastr --length 16 --type password
python3 vault.py add --service GitLab --username rastr --length 16 --type password

Listing Entries by specific name

python3 main.py list-entries --search GitLab
------------------------------------------
GitLab: username: rastr | secret: [N'}SS}.mvQK;C\"

Pattern matching

python3 main.py list-entries --search git*
------------------------------------------
GitLab: username: rastr | secret: [N'}SS}.mvQK;C\"
GitHub: username: rastr | secret: =;BU1o$v,Se*'"cE
