About This Hash Generator
Generate cryptographic hash digests from any text using the Web Crypto API built into your browser. All computation happens locally — your input is never transmitted anywhere.
Supported Algorithms
- MD5 — 128-bit hash, widely used for checksums (not for security)
- SHA-1 — 160-bit hash, legacy but still common for file verification
- SHA-256 — 256-bit hash from the SHA-2 family, used in TLS, Bitcoin, and more
- SHA-512 — 512-bit hash from the SHA-2 family, strongest option available
Common Use Cases
- Verify file integrity after download
- Generate checksums for data validation
- Compare expected vs. actual hash values
- Quick hash lookups for development and testing
