HashCalc Pro - Changelog

v1.0.14

April 24, 2026 Current

More accurate hash timings. The Stats tab now reports true compute-only per-algorithm times; shared file read time is reflected in overall wall-clock totals instead of being split across rows.
Faster hashing across the board. Selected algorithms now run in parallel across all CPU cores, improving scaling for multi-algorithm runs.
Double-buffered file I/O. Disk reads now overlap with hash computation, increasing throughput on large files.
Hot-path optimizations. RIPEMD-160 moved to native C; MD4, Tiger, SHA-512/224, SHA-512/256, Whirlpool, Panama, and SHA-3 absorption were optimized to reduce allocations and improve word-sized memory access.
Internals streamlined. Reduced allocations during streaming hashes and ongoing performance/code-quality improvements across the app.

Deep Apple Silicon optimization. CRC32 uses ARM hardware instructions; CRC64 uses PMULL carry-less multiply; SHA-512 truncated variants use ARMv8.2 crypto extensions; BLAKE3, SHA-3, Streebog, DSTU7564, and Grøstl leverage NEON SIMD paths.

Added 19 algorithms: BLAKE2s-256, CRC-64 (ECMA), SHAKE128, SHAKE256, Streebog-256/512 (GOST R 34.11-2012), SM3, KangarooTwelve (KT128), Skein-256/512/1024, eD2k, DSTU7564-256/384/512 (Kupyna), Grøstl-256/512, JH-256/512, and TTH (Tiger Tree Hash).

Monotonic run timer. Hash durations are no longer affected by system clock changes mid-run.
Hardened VirusTotal client. Lookups now use an isolated network session with explicit timeouts.

Snappier preferences. Theme, window, and option changes now persist via batched writes, reducing disk churn during adjustments.
Minor UI polish and small fixes throughout.

v1.0.13

April 24, 2026

Picker freeze fixed. Selecting HashCalc's own app file as the input no longer silently disables every later file and folder picker in the app.
Sidecar paths fixed under sandbox. Generated .hash files now correctly store portable, tilde-abbreviated source paths instead of full container-resolved paths.
Centered alert dialogs. All message dialogs now center on the app window instead of the screen.

Color-coded results. The status toast after a lookup is now tinted by detection severity — green for clean, amber for low, orange for medium, red for high, and deep red for critical.
Clearer status wording. Results now read like VT Detections: [3/72] → Low Risk for quicker at-a-glance reading.
API key link. The Options tab now links directly to VirusTotal's API key instructions.

Help page added. A new help section on the website covers basic usage, VirusTotal API key setup, sidecar files, and troubleshooting.
Help menu rebuilt. The macOS Help menu now links to online help, support, changelog, privacy policy, and the website.
Options polish. Hash files folder picker and related settings received minor UX touch-ups.
Website refresh. Small corrections and clarifications across the privacy, terms, marketing, and support pages.

v1.0.12

April 22, 2026

Toast notification system. Status messages across the app now present as consistent, animated toasts with proper timing controls.
Persistent file access. A security-scoped bookmark store remembers folders you've granted HashCalc access to, so hash output folders and recent files survive app restarts under the macOS sandbox.

Hashing engine streamlined. Simplified and modernized for better maintainability and reduced memory overhead.
Various small fixes to the Options tab.

v1.0.11

April 21, 2026

Product website launched. Privacy policy, terms of service, marketing page, and a support contact form are now live at hashcalc.pages.dev.
Additional App Store submission preparation.

v1.0.10

April 15, 2026

Credits tab added. A new tab listing acknowledgements for the algorithms and references behind the app.
Shift-click select/clear all. Holding Shift while clicking a hash algorithm toggle now toggles the entire default set on or off in one click.
Quit confirmation dialog. Opt-in confirmation before quitting, plus several other new options.

New theme palette. Refreshed accent colors, corner gradient fixes, and better readability in both light and dark appearances.
Credits tab always renders with dark content styling regardless of system appearance for a consistent look.
Copy rewording and additional polish throughout.

v1.0.9

April 12, 2026

Find hash field. A search bar in the results area lets you quickly locate an algorithm by name or by matching hex digits, with navigation between multiple matches.
More hash algorithms. Additional algorithm families were added to the lineup.

v1.0.4

April 11, 2026
