CargoCrypt v0.1.2 - Critical Fixes Release

CargoCrypt v0.1.2 Release Notes

🎉 Critical Bug Fixes Release

This release addresses critical issues discovered during testing that significantly impacted user experience and security.

🐛 Major Fixes

1. Filename Extension Bug Fixed 🔧

• Previous behavior: Files like .env would encrypt to .env..enc (double dot)
• Fixed behavior: Files now correctly encrypt to .env.enc
• Impact: This fix ensures compatibility with documentation and user expectations

2. Security: Password Prompting Implemented 🔐

• Previous behavior: All operations used hardcoded "temporary_password"
• Fixed behavior:
  • Encryption now prompts for password with confirmation
  • Decryption prompts for password
  • Passwords are securely handled using rpassword
• Impact: Major security improvement - CargoCrypt is now safe for real-world use

3. TUI Command Now Accessible 🖥️

• Previous behavior: TUI code existed but cargocrypt tui command was not available
• Fixed behavior: cargocrypt tui now launches the interactive terminal interface
• Impact: Users can now access the beautiful TUI dashboard as documented

📦 Installation

cargo install cargocrypt --version 0.1.2

🚀 Usage Examples

Secure Encryption with Password Prompt

$ cargocrypt encrypt .env
Enter password for encryption: ****
Confirm password: ****
✅ File encrypted: .env.enc

Interactive TUI Mode

$ cargocrypt tui
# Launches the interactive terminal interface

🙏 Acknowledgments
