# Update HashiCorp Packer on Windows

Production-ready bash script to securely update Win64 packer in WSL with comprehensive error handling, automatic backups, and integrity verification.

## Features

- **Secure Downloads**: Uses proper SSL certificate verification (no more `--no-check-certificate`)

- **Input Validation**: Validates version format and sanitizes inputs to prevent injection attacks

- **Automatic Backups**: Creates timestamped backups before updates with rollback capability

- **Integrity Verification**: SHA256 checksum verification for all downloads

- **Retry Logic**: Automatic retry with exponential backoff for network failures

- **Comprehensive Logging**: Detailed logging with timestamps to `/tmp/packer-update.log`

- **Atomic Operations**: Uses temporary directories to prevent partial installations

- **Signal Handling**: Graceful cleanup on interruption (Ctrl+C) with proper terminal color reset

- **Version Management**: Checks current version and skips if already installed

- **API Integration**: Uses HashiCorp releases API for version discovery

## Requirements

The following software must be installed in your WSL environment:

- [WSL](https://learn.microsoft.com/en-us/windows/wsl/install)

- `curl` - for secure downloads

- `unzip` - for extracting Packer archives

- `sha256sum` - for integrity verification
