Contains a kernel for the latest ODF 1.2 encryption implemented in
LibreOffice. The algorithm uses a SHA-256 checksum, a PBKDF2-HMAC-SHA1
key derivation with 100000 iterations and key stretching and AES-CBC
encryption.
Valid hashes can be extracted with the libreoffice2john.py script,
available from the John the Ripper Jumbo repository at
https://github.com/magnumripper/JohnTheRipper/blob/bleeding-jumbo/run/libreoffice2john.py
You have to remove the filename suffix at the end of the hash before
passing it to hashcat. Also see 'hashcat -m18400 --example-hashes'.
You can leave the filename prefix if you use the --username option to
process those hashes.
- Add hash-mode 18400 (Open Document Format (ODF) 1.2 (SHA-256, AES))
- Tests: add hash-mode 18400 (Open Document Format (ODF) 1.2 (SHA-256, AES))
The modification of existing core source files to add new hashcat kernels conflicts with the idea of having private hashcat kernel repositories especially when backporting latest hashcat core changes and new features.
The final outcome of this should be a plugin format that does not require modifications on the core soruce files.
Also convert all existing hash-modes to hashcat modules.
We'll start with dynamic loading the modules at runtime rather than linking them at compile time.
This will require some extra code for different OS types but should beneficial on a long term.
This commit add some first ideas of how such modules could look like, however there's no dynamic loading interface yet.
Next steps will be removing all hash-mode depending special code from source files and move them to the modules.
Finally merge with master.
Hardware Monitor: Renamed --gpu-temp-disable to --hwmon-disable
Fixed invalid warnings about throttling in case --hwmon-disable was used
Fixes https://github.com/hashcat/hashcat/issues/1757
Implement HMAC based on GOST 34.11-2012 Streebog-512 as well as a test
case for it. Both the PyGOST + hmac python module and the VeraCrypt HMAC
for Streebog-512 were used as references. The kernels expect the digests
to be in big-endian order according to the RFC examples for Streebog.
Fix two bugs from commit 224315dd62.
- Add hash-mode 11850: HMAC-Streebog-512 (key = $pass), big-endian
- Add test case for hash-mode 11850
- Bugfix for a3-pure Streebog kernels (modes 11700 and 11800)
- Rename a few Streebog constants in interface.h
