Overview of the tool
Raymond Lin’s MD5 & SHA Checksum Utility is a lightweight program for validating file integrity using cryptographic hashes. It creates checksum values so you can confirm a file hasn’t been altered or corrupted. The utility is designed to be straightforward and fast — ideal when you need a quick verification without installing a full suite of software.
Supported hash types
- SHA-256
- MD5
- SHA-384
- SHA-1
Using the program
- Open the utility.
- Select or drag the file you want to check into the application window.
- Choose which hash algorithm you want to compute.
- Click the button to generate the checksum and compare it against a known value.
These simple steps make verifying downloads or checking file integrity quick and repeatable.
Portable design and user interface
The application is fully portable, so you can run it from a USB drive or any folder without performing an installation. The interface is minimal and focused: pick a file, select an algorithm, and generate the hash. Because it doesn’t require configuration, it’s suitable for technicians and casual users alike.
When to use it
- Verifying downloads obtained from the internet
- Checking file transfers between systems
- Confirming backups haven’t been corrupted
- Quick integrity checks during troubleshooting
