How to check hash of downloaded file

Most common use of checksum is in checking if the downloaded file is corrupted. For instance, Ubuntu MATE download page includes SHA256 checksum for every image available there. So, after you downloaded an image, you can generate SHA256 checksum for it and verify if the checksum value matches the one mentioned on the site.

Being hash functions of a particular kind, cryptographic hash functions lend themselves well to this application too.

MD5 is a one-way hash algorithm which can be used for security or to verify the integrity of a file as it creates a digital signature for a file.

The File Checksum Integrity Verifier (FCIV) utility can generate MD5 or SHA-1 hash values for files to compare the values against a known good value. FCIV can compare hash values to make sure that the files have not been changed. With the FCIV utility, you can also compute hashes of all your critical files and save the values in an XML file 1. Find the file you downloaded to your computer. Right click on the file's icon and select digestIT from the menu. From the submenu that pops up choose Verify MD5 Hash. 2. Copy the MD5 Hash for the program you have downloaded and paste it into the "Message Digest to Verify" window that appeared after step 1. MD5 & SHA Checksum Utility is a standalone freeware that can generate MD5, SHA-1, SHA-256 & SHA-512 hashes from a file. assess the checksum of downloaded files and compare it against checksums What is a CHECKSUM file?
