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)
