Hash Calculator MD5 SHA256 vs Hex Editor

Need a hash calculator that just works? HashCalc computes MD5, SHA-1, SHA-256, SHA-384, SHA-512 and CRC32 the instant you type or paste — no upload, no wait, no guessing. Most "hash" tools send your text to a website or bury the digest you need under ads. HashCalc runs every algorithm locally on your device and shows the results side by side, so you can copy the exact digest you want and move on. WHAT YOU GET - Live digests for MD5, SHA-1, SHA-256, SHA-384, SHA-512 and CRC32 as you type - Verify a download in one step: paste the expected checksum and see match or mismatch instantly - Compare two hashes side by side to confirm two files or strings are identical - Sign messages with HMAC using your secret key across the full SHA family - Checksum any file — HashCalc streams it through the hasher so even large files hash cleanly - A saved history of recent hashes plus a plain-language reference on MD5, SHA, CRC32 and HMAC PERFECT FOR - Developers signing API requests and webhooks with HMAC - Anyone verifying a downloaded ISO, installer or backup against its posted checksum - Security-minded users checking file integrity without touching the cloud - Students and learners who want to see how hashing actually works WHY NOT JUST USE A WEBSITE? Web hashers make you paste sensitive text into a server you don't control, and they break the moment you lose signal. HashCalc computes everything on-device, works fully offline, and never sends your input anywhere. PRIVACY Every digest is computed on your device. No accounts, no servers, no tracking — your text and files never leave your phone. FULL ACCESS The free app covers core hashing. A HashCalc membership unlocks everything: all six algorithms, verify and compare, HMAC signing, file hashing and saved history. Choose a weekly or yearly plan, or a one-time lifetime purchase — subscriptions renew until cancelled and can be cancelled anytime. Type your first string and watch the digests appear.

"Hex Editor is built around precise hexadecimal editing rather than treating file inspection as an afterthought. Core search language includes hex editor, binary editor, hexadecimal editor, binary file, byte editor. Open a file, move through its byte data, search for a value or text sequence, copy what you need, change the required bytes, and save the result. Use the editor when a normal document viewer cannot show the actual bytes stored inside a file. Byte-level searching helps locate known signatures, strings, offsets, markers, or values without manually scanning an entire file. File Info gives you a quick view of basic file details before you begin deeper inspection. File Type Detector helps identify a file from its content when the extension is missing, unusual, or not enough for your workflow. Metadata Inspector provides another layer of context for understanding information carried by a file. Bit Inspector lets you move below the byte level and examine individual bits when binary representation matters. Hex Calculator is useful for hexadecimal arithmetic, offsets, values, and other low-level calculations. Byte Converter provides quick conversions when you need to move between byte-oriented values while analysing data. Text-Hex connects readable text with hexadecimal representation so you can investigate how characters appear in raw data. Encoding Converter helps you inspect data across supported character encodings instead of guessing how a byte sequence should be interpreted. Base64 Converter gives you a dedicated way to encode or decode Base64 data during technical investigations. String Scanner helps reveal readable text embedded inside binary content and can speed up an initial inspection. Hash Generator provides hashes for data checks and technical workflows where a repeatable fingerprint is useful. Checksum Tool supports checksum-oriented verification when you need to compare calculated values with expected data. Compare Files helps you identify differences between two files instead of relying on visual inspection alone. Entropy Analyzer provides a statistical view that can help you recognise changes in data characteristics across binary content. Byte Statistics summarises byte-level patterns so you can understand data distribution without reading every value individually. These tools work together for reverse engineering workflows, debugging, file inspection, data recovery preparation, protocol investigation, and general developer work. Hex Editor can also be useful when you need to confirm a small binary change, investigate an unknown file, or validate data before moving it elsewhere. Import your file into the toolkit, inspect the relevant region, make only the required edit, then save the resulting file for your next step. The app keeps common binary utilities close to the editor so you can move from editing to analysis without changing applications. Search, copy, inspect, convert, compare, calculate, and analyse from one mobile workspace. Free access provides limited usage, while Pro is designed for users who need unlimited Hex editing. Hex Editor does not replace specialised forensic or reverse-engineering suites; it provides a practical mobile toolkit for everyday hexadecimal and binary work. Use the editor for focused byte changes and use the supporting tools when the surrounding data needs more context. Whether you are checking a binary structure, looking for a string, comparing versions, or validating a checksum, the workflow stays centred on the file data itself. The interface is designed for direct access to low-level information without requiring a separate desktop utility for every small inspection task. Use it when a binary file needs a small, deliberate change rather than a complete rewrite. Inspect hexadecimal offsets when you need to understand where a value occurs in a file.
