FTK – Known File Filter (KFF)
Known file filter compares the hash
values of the files in your case against a
database of known hash values.


It can help you identify files that should be
ignored (i.e., operating system and
application files).
It can help you identify known files
pertinent to your case.
FTK – Known File Filter (KFF)
The hash value used is based on the
data contained in the file not its name
or extension.
The hash value can prove that the file
has not been altered.
Two common hashing algorithms are:


Message Digest 5 (MD5)
Secure Hash Algorithm (SHA)

To add custom hash values:

Use FTK or FTK Imager to create a hash
set and them import it into KFF.
