问题 In command-prompt, you can see the md5 or other hash of a file using certutil -hashfile <filepath> <hash algorithm> . This was the only option I can find to retrieving the hash of a file without encrypting it first. My question is if there is a way to hash a sentence or command outputs? What I am trying to figure out is if there is maybe a specific command that I can use in case like: set /p "var=input something" && <hash command> %var% or use certutil -hashfile with %var% instead of a file
