HashHarvest v0.8.0

[07-18-2026 17:01:08]

Added

• File-digest scan mode — hash_files() in extractor.py computes each file's own MD5/SHA1/SHA256/SHA512 digest, walking all files under the folder (not just supported document types) and returning the same result shape as extract() (line_no=None, "file digest" context). Exposed in the GUI as a Find hashes in text / Hash the files radio, wired through ScanWorker via a new mode parameter (extractor.py, main.py)
• VirusTotal lookup — new vt_lookup.py (lookup_hashes, verdict_from_stats) queries VirusTotal via vt-py; new VirusTotalDialog and VTLookupWorker plus a "VirusTotal" toolbar button check the current scan's unique hashes in a worker thread, showing per-hash malicious / suspicious / clean / not-found / error verdicts with detection counts, color-coded. SHA512 hashes are labeled n/a and skipped without an API call, since VirusTotal indexes only MD5/SHA1/SHA256 (vt_lookup.py, main.py)
• API-key storage with two backends — new keystore.py resolves the VirusTotal key from the VT_API_KEY environment variable, then the OS keychain (keyring), then QSettings; save_key() writes to the OS keychain (encrypted at rest) or QSettings (plaintext) and removes the copy from the other backend. A "Store key in OS keychain (encrypted at rest)" checkbox opts in when keyring is available (keystore.py, main.py)
• .env support — _load_dotenv() loads VT_API_KEY (and other KEY=VALUE lines) from a .env file next to the app at startup, so the key can live in a git-ignored file instead of the GUI; environment variables take precedence (main.py)
• "Latest build date" label in the header showing the executable's (or source file's) modification time as MM/DD/YYYY HH:MM:SS (main.py)
• HashHarvest.spec PyInstaller build file with UPX compression, Qt/stdlib exclusions, and vt / keyring.backends.Windows declared as hidden imports so packaged builds include the optional features (HashHarvest.spec)

Changed

• Version bumped to v0.8.0 in the GUI version label and window title (main.py)
• requirements.txt — added vt-py, plus optional keyring for encrypted key storage
• README.md and USAGE.md — documented the two scan modes, VirusTotal lookup, API-key configuration (env var / .env / GUI field) and plaintext-vs-encrypted storage, and rewrote the build section for the spec + UPX workflow with shipping guidance (ship only the .exe; the empty database is created on first run)
