SSH Key Generator

This repository contains a Python script that automates the process of generating SSH keys for a list of users. It supports generating random passphrases for each key and allows specifying the key type.

Features

  • Generate SSH keys for multiple users.
  • Supports RSA, DSA, ECDSA, and ED25519 key types.
  • Optionally generate a random passphrase for each key.
  • Store key information, including username, key name, passphrase, and public key fingerprint, in a user info file.

Usage

  1. Prepare a list of users: Create a text file with one username per line.

  2. Run the script: Execute the script with the path to your user list file as an argument.

python ssh_key_generator.py -t rsa -p user_list.txt
  • -t or --key-type: Specify the key type (default is rsa).
  • -p or --passphrase: Generate a random passphrase for each key.
  • -e or --excel: Export output to an Excel file.
  • user_list: Path to the user list file.

Example

./genpair -t ed25519 -p -e user_list.txt

This command will generate ED25519 keys with random passphrases for each user listed in user_list.txt and user_list.xlsx.

Output

The script will create SSH keys in the output directory and store key information in a file named user_info. The information includes the username, key name, passphrase (if generated), and public key fingerprint.

Requirements

  • Python 3.6 or higher
  • ssh-keygen command available in the system's PATH
