Contains a kernel for the ODF 1.1 encryption implemented in OpenOffice.
The algorithm uses a SHA-1 checksum, a PBKDF2-HMAC-SHA1 key derivation
with 1024 iterations and Blowfish-CFB 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 -m18600 --example-hashes'.
You can leave the filename prefix if you use the --username option to
process those hashes.
- Add hash-mode 18600 (Open Document Format (ODF) 1.1 (SHA-1, Blowfish))
- Tests: add hash-mode 18600 (Open Document Format (ODF) 1.1 (SHA-1, Blowfish))
There are approx. 240 snprintf calls that set the target buffer size to
out_len - 1 or similar. This "mind the null character" subtraction is
unnecessary since snprintf already includes the string termination into
the given buffer size.
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.

available from the John the Ripper Jumbo repository at

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))
