Hash Generator
Generate cryptographic hashes from text or files in real-time. Supports MD5, SHA-1, SHA-256, SHA-384, and SHA-512. Your data never leaves your device.
Algorithm
Drop a file to hash it
Frequently Asked Questions
- Is this hash generator free?
- Yes, 100% free. No account, no limits required.
- Are my files and text safe?
- All hashing runs locally in your browser using the Web Crypto API. Nothing is uploaded to any server.
- What is the difference between MD5, SHA-1, SHA-256, and SHA-512?
- MD5 and SHA-1 are older algorithms with known vulnerabilities — use them only for checksums, not security. SHA-256 and SHA-512 are part of the SHA-2 family and are cryptographically secure. SHA-512 produces a longer hash and is slower but offers a larger output space.
- Can I hash a file to verify its integrity?
- Yes. Drag and drop any file onto the input area, select your algorithm, and the hash will be computed entirely in your browser. Compare it to the publisher's checksum to verify integrity.
- What is a hash used for?
- Hashes are used for data integrity verification (checksums), password storage (with salted SHA algorithms or bcrypt), digital signatures, and deduplication.
- Does it work on mobile?
- Yes, works on all modern browsers including mobile Safari and Chrome on iOS and Android.
