How do I generate a hash?

Type or paste your text in the input field. SHA-1, SHA-256, SHA-384, and SHA-512 hashes are generated instantly and displayed below. Click 'Copy' next to any hash to copy it to your clipboard.

What is a cryptographic hash?

A cryptographic hash is a fixed-length fingerprint of data produced by a hash function. The same input always produces the same output, but the original input cannot be recovered from the hash. Common uses include data integrity verification and password storage.

Is the hash generator free?

Yes, completely free. Hashes are generated using the built-in Web Crypto API in your browser — no data is ever sent to any server, and no signup is required.

About SHA Hash Algorithms

SHA-1 — 160-bit hash; deprecated for security use, still common in checksums and Git
SHA-256 — 256-bit hash; widely used in TLS certificates, Bitcoin, and data integrity checks
SHA-384 — 384-bit hash; stronger variant of SHA-256 for higher security requirements
SHA-512 — 512-bit hash; maximum strength in the SHA-2 family, used in high-security contexts

Hashes are generated using the browser's built-in Web Crypto API. Your input never leaves your device.
