Hash Generator – MD5, SHA-1, SHA-256, SHA-512 Free
Generate cryptographic hashes instantly in your browser. Supports MD5, SHA-1, SHA-256 and SHA-512 for both text and file input. All hashing is 100% client-side — your data never leaves your device.
4 Hash Algorithms
MD5, SHA-1, SHA-256 and SHA-512 — all four generated simultaneously so you can choose the algorithm you need.
File Hashing
Drag and drop or select any file to hash it. The entire file is processed in your browser — no upload to any server.
Hash Comparison
Paste an expected hash to instantly verify whether it matches any generated hash — green for match, red for mismatch.
100% Client-Side
All hashing uses the browser's native Web Crypto API. Your text and files are never sent to any server — fully private.

📖 How to Generate a Hash
Enter Text or Upload a File
Type or paste text into the text input, or switch to File Input and drag/drop any file. Hashing happens live as you type.
View All Four Hashes
MD5, SHA-1, SHA-256 and SHA-512 are all generated simultaneously. Click any Copy button to copy an individual hash.
Compare a Hash (Optional)
Tick Compare Hash and paste an expected hash to verify it. The result turns green if it matches any algorithm's output, red if it does not.
Copy All or Individual
Click Copy All Hashes to copy all four in a labelled block, or copy individual hashes with their per-row Copy button.

| Algorithm | Output Length | Security Status | Common Use |
|---|---|---|---|
| MD5 | 128-bit / 32 hex chars | ⚠️ Broken (collisions) | Legacy checksums, non-security hashing |
| SHA-1 | 160-bit / 40 hex chars | ⚠️ Deprecated | Git commit IDs, legacy systems |
| SHA-256 | 256-bit / 64 hex chars | ✅ Current standard | File integrity, digital signatures, TLS |
| SHA-512 | 512-bit / 128 hex chars | ✅ High security | High-security applications, HMAC |
Common Use Cases
- File integrity verification — compare a downloaded file's hash against the publisher's published checksum to confirm the file hasn't been tampered with or corrupted.
- Data deduplication — hash files or records to detect duplicates without comparing full content.
- API development — generate HMAC seeds, test hash-based authentication flows, or produce consistent test fixtures.
- Learning cryptography — type text and see how a single character change produces a completely different hash (avalanche effect).
