Our File Checksum Utility is written entirely in Java, therefore it is platform independent and runs on most operating systems, including Windows & Linux.
Protect your data with confidence!
* Verify file uploads and downloads
* Ensure successful file backup copies
* Ensure files burn to CD or DVD correctly
Immediately diagnose and identify data corruption for corrective action!
Your file is examined byte-by-byte to generate a hashcode "fingerprint" value unique to your file.
This diagnostic utility supports:
* 32-bit Standard CRC-32 checksum
* 128-bit RSA MD5 Message Digest
* 160-bit Ultra-Secure SHA-1 checking
Great for ensuring 100% accurate, successful & complete data transfer and backup of critical business or personal files!
Run our utility against the original file, then run it against the copy. If the fingerprint values match, you know the files are 100% identical and have copied, transferred, or downloaded correctly.
