Hash Generator
Generate MD5, SHA-1, SHA-256 Hashes
Compute cryptographic hashes for any text or file directly in your browser. MD5, SHA-1, SHA-256, SHA-384, and SHA-512 — all computed instantly with zero server uploads.
Hashes compute automatically as you type
What Is a Hash Generator?
A hash generator computes a fixed-length cryptographic fingerprint for any piece of data — whether it is a short string of text or a multi-gigabyte file. The resulting hash (or digest) is a hexadecimal string that uniquely represents the input. Even a single-character change produces a completely different output, making hashes invaluable for verifying data integrity, detecting duplicates, and creating content fingerprints.
Our Hash Generator computes five widely used algorithms simultaneously — MD5, SHA-1, SHA-256, SHA-384, and SHA-512 — directly in your browser using the Web Crypto API and a built-in MD5 implementation. No data is ever sent to a server.
For text input, hashes recalculate automatically as you type with a 400ms debounce, giving you instant feedback. For files, simply drag-and-drop or browse — the tool reads the file as a raw ArrayBuffer and computes all five hashes in parallel.
The built-in Compare feature lets you paste a known hash value and instantly see which algorithm matches your computed result. Combined with one-click copy, uppercase / lowercase toggle, and Copy All, this tool covers every common hashing workflow — from verifying software downloads to generating checksums for release documentation.
Discover Features
Five algorithms, real-time hashing, file support, hash comparison, and full privacy — all in your browser
Text & File Hashing
Hash any text by typing or pasting, or upload any file — images, documents, executables, archives. The tool reads files locally as ArrayBuffers for fast, accurate hashing without server uploads.
Five Algorithms
Compute MD5, SHA-1, SHA-256, SHA-384, and SHA-512 simultaneously. SHA hashes use the Web Crypto API (SubtleCrypto) for native-speed performance; MD5 uses a built-in JavaScript implementation.
Hash Comparison
Paste a known hash into the compare field and instantly see which algorithm matches. A green checkmark highlights a match; a red X marks a mismatch — perfect for verifying downloads and file integrity.
One-Click Copy
Copy any individual hash value or all five at once with a single click. The 'Copy All' button formats all hashes as an algorithm-labeled list ready for documentation, tickets, or release notes.
Auto-Compute on Type
Hashes recalculate automatically as you type with a 400ms debounce, giving you real-time feedback without needing to click a button. File hashes compute instantly after selection.
100% Private & Secure
All hashing happens entirely in your browser using the Web Crypto API and JavaScript. No data is ever sent to any server. Close the tab and nothing remains — ideal for sensitive files and credentials.
How to Use
Four steps: choose input, enter data, review hashes, and copy or compare
Choose Input Mode
Select the 'Text Input' tab to type or paste text, or the 'File Upload' tab to drag-and-drop or browse for any file on your device.
Enter Your Data
Type, paste, or upload the content you want to hash. For text, hashes compute automatically as you type. For files, hashing begins immediately after selection.
Review All Hashes
All five hash results — MD5, SHA-1, SHA-256, SHA-384, SHA-512 — appear simultaneously. Toggle between lowercase and uppercase hex output as needed.
Copy or Compare
Copy any individual hash or all five at once. Use the Compare feature to paste a known hash and verify which algorithm matches your computed result.
Use Cases
Common scenarios where cryptographic hashing saves time and ensures data integrity
Verify File Downloads
Compare the SHA-256 hash of a downloaded file against the checksum published by the author to confirm the file has not been tampered with or corrupted during transfer.
Password & Token Hashing
Generate quick SHA-256 or SHA-512 hashes of passwords and tokens for comparison or storage reference. Ideal for verifying credentials without exposing the original value.
Software Release Checksums
Generate MD5 and SHA-256 checksums for build artifacts, installers, and packages. Publish these alongside your releases so users can verify integrity before installation.
Document Integrity Audit
Hash important documents (contracts, legal filings, evidence) and store the hash as a tamper-proof fingerprint. Re-hash later to prove the document has not been altered.
Data Deduplication
Hash files or data chunks to generate unique fingerprints. Identical hashes indicate duplicate content, enabling efficient storage and backup strategies without byte-by-byte comparison.
Forensics & Security
Compute hashes of disk images, log files, and evidence for chain-of-custody documentation. Matching hashes prove data integrity across transfers and storage.
