#Author - Sagnik Chandra
# """
# PassSwift: A Python script for streamlined password management tasks.
#
# This script provides several functionalities for password management:
# - Password generation: Generate strong passwords with customizable criteria.
# - Password strength checker: Evaluate the strength of passwords based on various criteria.
# - Password wordlist check: Check if a password is present in a common wordlist.
# - Secure password storage: Encrypt and store passwords with website and username in a file.
# - Password file reading: Read and decrypt passwords stored in the password file.
# - Hash method identification: Identify the hash method (algorithm) of a given hash value.
#
# Author: Sagnik Chandra.
# GitHub: https://github.com/MIISTERC
# Instagram: https://www.instagram.com/sc17_kali/
#
# Usage:
# - Run the script and follow the interactive menu prompts to perform password management tasks.
# - Ensure that you have the required dependencies installed. See requirements.txt for details.
