The Tip of the Night for December 5, 2015, discussed how to use the certutil command in Windows to generate a hash value for a specific file. You can also use the below script, first posted here, to generate a list of hash values for multiple files in a single folder
for %F in (*) do @certutil -hashfile "%F" MD5 | find /v "hashfile command completed successfully" >>list.txt
After entering command prompt, use the cd command to change the directory to the folder containing the files you need to process. Simply enter this script and then press return. A new file will be generated like this:
certutil can also generate SHA1 and SHA256 hash values. Sadly, this script as written will not give you the hash values for the files saved in subdirectories.
