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))
