Show estimated training times for CUDA/MPS/CPU before starting a
training run. Add device selection prompt with cuda as the default.

Training previously loaded entire wordlists into RAM and tokenized all at
once, causing OOM on large files like rockyou.txt. This adds memory
estimation, lazy dataset loading, and training optimizations.
- Add _get_available_memory_mb() for cross-platform RAM detection
- Add _estimate_training_memory_mb() to predict peak usage before loading
- Replace bulk tokenization with LazyPasswordDataset (file offset index + on-the-fly tokenization)
- Add --max-lines flag to limit training to first N lines
- Add --memory-limit flag to auto-tune --max-lines based on available RAM
- Enable gradient checkpointing and gradient accumulation (steps=4)
- Enable fp16 on CUDA devices

Add ability to fine-tune PassGPT models on custom password wordlists.
Models save locally to ~/.hate_crack/passgpt/ with no data uploaded to
HuggingFace (push_to_hub=False, HF_HUB_DISABLE_TELEMETRY=1). The
PassGPT menu now shows available models (default + local fine-tuned)
and a training option. Adds datasets to [ml] deps and passgptTrainingList
config key.

- Add optional startup version check against GitHub releases (check_for_updates config option)
- Add packaging dependency for version comparison
- Fix PassGPT OOM on MPS by capping batch size to 64 and setting memory watermark limits
- Fix PassGPT output having spaces between every character
- Hide PassGPT menu item (17) unless torch/transformers are installed
- Fix mypy errors in passgpt_generate.py with type: ignore comments
- Update README with version check docs, optional ML deps section, and PassGPT CLI options
- Add test_version_check.py with 8 tests covering update check behavior

Add PassGPT as attack mode 17, using a GPT-2 model trained on leaked
password datasets to generate candidate passwords. The generator pipes
candidates to hashcat via stdin, matching the existing OMEN pipe pattern.
- Add standalone generator module (python -m hate_crack.passgpt_generate)
- Add [ml] optional dependency group (torch, transformers)
- Add config keys: passgptModel, passgptMaxCandidates, passgptBatchSize
- Wire up menu entries in main.py, attacks.py, and hate_crack.py
- Auto-detect GPU (CUDA/MPS) with CPU fallback
- Add unit tests for pipe construction, handler, and ML deps check

OMEN uses lowercase `makefile` which was missed by the capital-M check.
On case-sensitive filesystems (Linux) this meant OMEN wouldn't be built
during `make submodules`.

The handler was prompting for training source and max candidates even
when the OMEN binaries weren't built, leading to confusing error output.
Now checks for createNG and enumNG up front and returns with a build
instruction if either is missing.

Add OMEN (Ordered Markov ENumerator) as a probability-ordered password
candidate generator. Trains n-gram models on leaked passwords via
createNG, then pipes candidates from enumNG into hashcat.
Also fix a pre-existing bug where ensure_binary() used quit(1) instead
of sys.exit(1) - quit() closes stdin before raising SystemExit, which
caused "ValueError: I/O operation on closed file" when any optional
binary check failed and the program continued to use input().

Reuses existing _count_computer_accounts() and _filter_computer_accounts()

Add TestE2EPreprocessingFlow class that simulates the exact main()
preprocessing logic (format detection, filtering, NT/LM extraction)
with realistic secretsdump.py output. Covers: filter accept/decline,
no computers, all computers, LM hash detection, domain\computer$
format.

Add TestWriteFieldSortedUnique (7 tests) and TestPwdumpFilterPipeline
(8 tests) covering the full filter -> extract NT/LM pipeline. Add
edge case tests for unicode, BOM, long lines, permissions, and
delimiter handling.

- Add type hints to _filter_computer_accounts and _dedup_netntlm_by_username
- Fix unclosed file handle when reading hash file for format detection
- Extract _count_computer_accounts helper to eliminate duplicate file reads
- Stream _filter_computer_accounts output instead of collecting in memory
- Only write .dedup file when duplicates actually exist
- Add tests for _count_computer_accounts, malformed lines, and no-file-on-zero-dupes

- Detect and optionally filter Windows computer accounts (username
ending with $) from pwdump-format NTLM hash files (type 1000)
- Detect and optionally deduplicate NetNTLMv1/v2 hashes (types
5500/5600) by username, keeping first occurrence
- Add 10 tests covering both features

Tests use HATE_CRACK_SKIP_INIT=1 and don't need submodules.

download_wordlist() now resolves relative filenames against
get_hcat_wordlists_dir() instead of saving to cwd. Also ensures

The test built its own mock context instead of using the shared
ollama_globals helper, missing the rulesDirectory and hcatPotfilePath
patches. This caused FileNotFoundError on CI where /path/to/hashcat/rules

Add LLM Attack (option 15) to menu listing and attack descriptions,

- Mock rulesDirectory in ollama test fixture so hcatOllama doesn't
fail with FileNotFoundError on CI where /path/to/hashcat/rules

- Update pre-push hook to match CI env vars (HATE_CRACK_SKIP_INIT=1)

Remove ollamaWordlist config key and all references. Wordlist mode now
requires the cracked hashes .out file to exist and extracts passwords

Remove 500-line wordlist cap and send the entire file to Ollama.

ollamaCandidateCount config.

Rename markov_attack → ollama_attack and hcatMarkov → hcatOllama across
