WinHasher
Very simple file and text hashing tool for Windows
Tiny script will find hash digest of files or text by calling on Microsoft's "certutil.exe", using MD4, MD5, SHA1, SHA256, SHA384, or SHA512. Simple and self explanatory.
*EDIT 5/3/25, I just realized that there is another project entitled "WinHasher", it appears to kind of do the same thing but uses native code rather than Microsoft's "certutil". If that's what you're looking for, it's here: https://github.com/gpfjeff/winhasher
