#### Fast multi-threaded checksum calculator (CRC32, MD5, SHA1, SHA256, SHA512)

Slashsum calculates 5 different checksums simultaneously using parallel processing.

⚡ FEATURES
• Calculate CRC32, MD5, SHA-1, SHA-256, SHA-512 in one command
• Parallel processing - 5 hashes at the speed of 1
• Large file support (tested with 50GB+ files)
• Save results to .checksum files
• Cross-platform (Linux, Windows, macOS)

🚀 USAGE
slashsum myfile.iso # Calculate checksums
slashsum myfile.iso --save # Save to file.checksum

📊 PERFORMANCE
Calculates 5 checksums in approximately the same time as a single checksum tool, because disk I/O is the bottleneck, not CPU.

🔧 PERMISSIONS
• home: Access files in your home directory
• removable-media: Access USB drives and external disks

INSTALL:

```
  sudo snap install slashsum

  # Connect missing permissions  ( if needed)
  sudo snap connect slashsum:home
  sudo snap connect slashsum:removable-media

  hash -r  # Refresh shell path cache
  slashsum --version
```
