KeePass 2 database master-password cracker
Hi Thorsten,
I need to recover a kdbx database with keyfile and therefore would like to use your nice program. Unfortunately it doesn't seem to work in my case.
I created two test databases (Keepass 2.24, Windows 10, x64): tests.zip
One with a corresponding keyfile, one without.
Both use as master keyword: test
mod0keecrack was created using VS 2015 community edition on the same computer.
If I run the following command:
echo test | mod0keecrack.exe keecrack-test-nofile.kdbx
I get the following output:
[*] using db: keecrack-test-nofile.kdbx
[*] using key: keecrack-test-nofile.key
[*] kdbx header:
[-] file magic: 9aa2d903
[-] file identifier: b54bfb67
[-] file minor version: 0001
[-] file major version: 0003
[*] kdbx headerentries:

So there is no indication that the correct password has been found. The same for the one with the keyfile.
Any ideas?
Cheers,
