Pressing Settings gives access to an impressive selection of 27 additional hash values that can all be displayed. One major limitation HashTab has compared to HashCheck is it only works on one file at a time. After right clicking on the file and going to Properties, the tab is called “File Hashes” and you will get CRC32, MD5 and SHA-1 hash values displayed by default. HashTab is another tool that uses the system file properties window to show file hashes and is quite similar to HashCheck. The 7z.exe command line tool has this function by using the “h” command along with a hash switch “-scrc. Do note that when you select multiple files 7-Zip will give the overall checksums for all files added together and not each file individually. Just right click on a file and go to “CRC SHA” and the options will be available to get a checksum for CRC-32, CRC-64, SHA1, SHA256, or the asterisk will get all at once (including BLAKE2sp). A few years later a function was added to 7-Zip that introduced a context menu entry where you can quickly check a file’s integrity through the program’s user interface. The ability to verify file checksums with CRC or SHA has been in 7-Zip since 2011.

Not least because of its 7z archive format that can achieve great compression ratios. 7-Zip is probably the most popular and well known free file archiver around today.
