Microsoft File Checksum Integrity Verifier


Microsoft File Checksum Integrity Verifier
is a command line
utility that computes and verifies hashes of files.

It computes a MD5 or SHA1 cryptographic hash of the content
of the file. If the file is modified, the hash is
different.

With FCIV, you can compute hashes of all your sensitive
files. When you suspect that your system has been compromised, you
can run a verification to determine which files have been modified.
You can also schedule verifications regularily.
