Validate your files with SHA1 MD5 Checksum Utility
Want to confirm if the file you just downloaded has all the parts to it and none are missing and it’s not compromised. Before the file is burnt to a DVD or installed in your system, its a good practice to check the integrity of the file and avoid future problems/errors. Most of the websites from where you download files may also have a cryptographic hash key generated for that particular file. Checksum utilities are used to verify the integrity of generated hashes. You can then compare that hash key with the hash key generated by the utility and validate it. Two of the most common cryptographic hash functions are the Secure Hash Algorithm (SHA1) and Message Digest Algorithm 5 (MD5)
I use the “MD5 & SHA-1 Checksum Utility” by Raymond Lin. it is a standalone freeware utility that generates and verifies cryptographic hashes in SHA1, MD5, SHA-256 and SHA-512. The size of the utility is a mere 81.5kb that is compatible with Windows XP/2003/Vista/Server 2008/Windows7 & Windows8.
Download.cnet.com hosts this file and has scanned it to ensure it is virus and spyware free. Check out Raymond’s Blog for more information. If you require more features that allows you to generate CRC32 & SHA-384 hash files etc. then there is also a PRO version available.
It’s a very simple, stand-alone exe file that does not install in your system. Just run it each time you want to verify the hash to ensure the file integrity is correct with the matching file. Happy SHA1 MD5 verification…
