Fast, reliable, and privacy-focused, HashCalc lets you calculate, verify, and audit file and text integrity using industry-standard cryptographic algorithms.

🔑 Key Features:

⚡ Comprehensive Cryptographic Suite
Generate checksums and hashes for text or files instantly using MD5, SHA-1, SHA-224, SHA-256, SHA-384, SHA-512, SHA3-256, SHA3-512, RIPEMD-160, and CRC32 — 10 algorithms in one app.

📁 Batch File Processing — Free & Unlimited
Process multiple files simultaneously, at no cost. Inspect checksums for entire file batches, organize results, and export them to CSV.

⚖️ File vs. File Comparator
Select two files side by side and instantly see whether they're byte-for-byte identical — with a clear verdict and a breakdown of exactly what differs (size or content) when they're not.

🔐 HMAC Keyed-Hashing — Free for Text & Files
Generate Keyed-Hash Message Authentication Codes (HMAC) with custom secret keys (text or hex) across MD5 through SHA-512 and SHA3-256/SHA3-512 — free for both text and file hashing. Includes quick presets for verifying GitHub, Stripe, and Shopify webhook signatures.

📋 Checksum Manifest Verification — Free
Import standard checksum manifests (.sfv, .sha256sums, SHA256SUMS, and similar) and verify your files against them automatically.

🌐 Remote File Checksums (URL Hashing)
Calculate checksums directly from remote HTTP/HTTPS URLs without needing to save files to your local storage first (3 free lookups per day, unlimited with Pro).

🔬 Forensic Audit & Shannon Entropy Analysis
Deep-dive into file randomness and cryptographic strength. Every hash result includes an automatic entropy analysis and integrity verdict based on Shannon Entropy, flagging legacy/collision-prone algorithms — with a real, interactive SHA-1 collision demo (the 2017 "SHAttered" attack) showing exactly why MD5 and SHA-1 are no longer considered safe.

🧂 Salting & Key Derivation Visualizer
A hands-on, educational tool for understanding password security: visualize salting, and compare PBKDF2, bcrypt, Argon2id, and scrypt key derivation in real time — four industry-standard methods side by side.

📤 Share-to-Hash
Share any file directly from your file manager or any other app straight into HashCalc — it hashes it instantly, no manual searching required.

🎯 Real-time Integrity Comparison
Compare hash values against expected signatures with color-coded matching and instant pass/fail visual cues. Includes a built-in hash-type detector and one-tap VirusTotal lookup.

📊 History Management
Save your calculation history locally and search past operations (last 10 entries free, 50 with Pro).

🔒 Privacy First, Local-First Engine
All hashing, HMAC, and forensic analysis run 100% locally on your device — your files, text, and keys never leave it. The only exception is the optional "Remote URL" feature, which routes solely the requested download through a secure proxy so your device can fetch it; the file is streamed straight to you and never stored.

💎 HashCalc Pro Features:
Unlock the full potential of HashCalc for heavy workloads:
• Unlimited Remote URL Fetching
• Full History (50 entries) + Export
• PDF Forensic Report Export
• Ad-free, uninterrupted workflow

Verify data integrity with mathematical precision and professional-grade cryptographic analysis. ✨ ## Rankings - #2,109,235 — Overall ## Permissions and access ### Permissions - `android.permission.ACCESS_ADSERVICES_AD_ID` - `android.permission.ACCESS_ADSERVICES_ATTRIBUTION` - `android.permission.ACCESS_ADSERVICES_TOPICS` - `android.permission.ACCESS_NETWORK_STATE` - `android.permission.FOREGROUND_SERVICE` - `android.permission.INTERNET` - `android.permission.READ_EXTERNAL_STORAGE` - `android.permission.VIBRATE` - `android.permission.WAKE_LOCK` - `android.permission.WRITE_EXTERNAL_STORAGE` - `com.android.vending.BILLING` - `com.android.vending.CHECK_LICENSE` - `com.antotech.hashcalc.DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION` - `com.google.android.gms.permission.AD_ID` ## Similar extensions and apps - [HashCalc: MD5, SHA, HMAC](https://chrome-stats.com/d/com.goyalsoftech.hashcalc) — 59,391 users, 4.17 / 5 - [Hash Calc (Checksum Utility)](https://chrome-stats.com/d/com.gmail.kevinhhldev.hashcalc) — 21,730 users, 4.10 / 5 - [Hash Check - Hash Calculator](https://chrome-stats.com/d/com.dynamikwizard.hashcheck) — 3,442 users - [Simple Hash Checker](https://chrome-stats.com/d/com.appcraft.hashchecker) — 3,725 users - [Checksum Calculator](https://chrome-stats.com/d/info.camposha.checksum_calculator) — 143 users - [Hash Checker: MD5, SHA, CRC-32](https://chrome-stats.com/d/com.smlnskgmail.jaman.hashchecker) — 150,509 users, 4.42 / 5 - [Hash Hand - MD5 SHA BLAKE&more](https://chrome-stats.com/d/com.greyelastic.hashhand) — 132 users - [Hash Checker & Generator](https://chrome-stats.com/d/com.santodev.hashgen) — 18,537 users, 2.86 / 5 - [Hash Generator: SHA MD5 HMAC](https://chrome-stats.com/d/com.tahatec.hash_generator) — 15,211 users, 2.40 / 5 - [Hash King - Hash Generator](https://chrome-stats.com/d/com.md.hashgenerator) — 280 users - [HashLock - Hash & Verify Tool](https://chrome-stats.com/d/com.application.riwayat_riwayat_9isas_lhob_zawaj) — 15 users - [Hash Gen - Hash Generator](https://chrome-stats.com/d/com.orpcode.md5hashgenerator) — 9,533 users --- Source: [Chrome-Stats](https://chrome-stats.com/d/com.antotech.hashcalc)
