cryptkey

cryptkey is a minimalist command-line utility written in Go for generating cryptographically secure random keys. It offers options for generating 8-byte, 16-byte, or 32-byte hexadecimal keys, making it suitable for quick key generation for various applications.

Features

• Secure Key Generation: Utilizes crypto/rand for robust, cryptographically secure random key generation.
• Flexible Key Lengths: Supports 8, 16, and 32-byte key outputs.
• Clipboard Integration: Designed to be easily piped with OS-specific clipboard utilities for instant use.

Usage

To generate a key, simply run the cryptkey executable. By default, it will output a 32-byte hexadecimal key.

cryptkey

Options

• -8: Generate an 8-byte key.
• -16: Generate a 16-byte key.
• -32: Generate a 32-byte key (default).

If multiple length flags are provided, the first one encountered will take precedence.

Examples

Generate a 16-byte key:

cryptkey -16

Integrate with your system's clipboard for immediate use:

• Windows:

  cryptkey -16 | clip
  

• macOS:

  cryptkey | pbcopy
  

• Linux (requires xclip):

  cryptkey | xclip -selection clipboard
  

Installation

From Source

1. Clone the repository (or download the main.go file):

   git clone https://github.com/your-username/cryptkey.git # Replace with your repo
   cd cryptkey
   

2. Build the executable:

   go build -o cryptkey main.go
   

3. Optional: Move to PATH: For system-wide access, move the cryptkey executable to a directory included in your system's PATH (e.g., /usr/local/bin on Linux/macOS, or a directory added to Path environment variable on Windows).

   # On Linux/macOS
   sudo mv cryptkey /usr/local/bin/
   

Via go install

go install github.com/theaaronn/keycrypt
