slashsum

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.
