Hash Generator
Generate MD5, SHA-1, SHA-256, and SHA-512 hashes from any text. All hashing is done locally in your browser using the Web Crypto API — nothing is sent to any server.

About Hash Generator
This hash generator computes cryptographic hashes of any text input using five common algorithms. All hashing runs entirely in your browser using the Web Crypto API — no data is ever sent to a server.
Supported Algorithms
- MD5MD5 (128-bit) — Fast but cryptographically broken. Suitable for checksums, not security.
- SHA-1SHA-1 (160-bit) — Deprecated for security use. Still used in Git and legacy systems.
- SHA-256SHA-256 (256-bit) — Industry standard. Used in SSL/TLS, blockchain, and digital signatures.
- SHA-512SHA-512 (512-bit) — Strongest in the SHA-2 family. Maximum security for critical applications.
Common Uses
- Verify file integrity and data consistency
- Hash passwords (with proper salting — never raw)
- Generate unique identifiers for data deduplication
- Create digital signatures and message authentication codes
