About Hash Generator
This tool generates cryptographic hashes using MD5, SHA-1, SHA-256, and SHA-512 algorithms. All hashing is done in your browser using the Web Crypto API — your data never leaves your device.
Supported Algorithms
- MD5 — 128-bit hash, widely used for checksums (not secure for passwords)
- SHA-1 — 160-bit hash, legacy use
- SHA-256 — 256-bit hash, industry standard for security
- SHA-512 — 512-bit hash, maximum security
