With hash-mode 9600 (MS Office 2013) there can be multiple hashes with
the same salt but with different encryption verifiers in esalt_bufs.
This commit adds the functionality to execute _comp kernels for
different hashes after deriving their common key once.
Fixes#1826
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))
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.

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))
Remove unnecessary constant variables by hardcoring values instead of
looking up. Precalculate swaps that are known at compile time. Hardcode
hashes_shown offset as zero for all TC / VC kernels.
Adds suport for the Japanese cipher Camellia with 256-bit keys as used
by VeraCrypt.
- Add Camellia header decryption checks to all VeraCrypt kernels
- Add test containers for remaining cipher combinations
Adds support for the Russian cipher specified in GOST R 34.12-2015, also
known as Kuznyechik (Grasshopper).
- Add Kuznyechik header decryption checks to all VeraCrypt kernels
- Add test containers for available Kuznyechik cipher combinations
The 7zip, scrypt and stdout kernels differ from the others in their
function declarations somewhat. Unify them and substitute with macros.
Also remove a few superfluous (bogus) consts which were introduced in
the previous PR.
Substitute long parameter lists in ~2900 kernel function declarations
with macros. This cleans up the code, reduces probability of copy-paste
errors and highlights the differences between kernel functions. Also
reduces the size of the OpenCL folder by ~3 MB.
Most of the kernel functions use nearly identical parameter lists.
Essentially, there are four parameters that vary, except for a dozen odd
kernel functions (e.g. stdout, zip, scrypt). This means that the function
declarations can be hidden behind a few simple macros with up to two
parameters.
In preparation for the abstraction of long repetitive kernel function
declarations, rename the salt buffer pointers to *esalt_bufs. Also
declare them const where they are not.
