Supported Hash Algorithms
This tool generates hashes using four industry-standard algorithms from the SHA family:
- SHA-1 — 160-bit hash (40 hex characters). Legacy algorithm, still used for checksums but not recommended for security.
- SHA-256 — 256-bit hash (64 hex characters). The most widely used secure hash. Powers Bitcoin, TLS certificates, and code signing.
- SHA-384 — 384-bit hash (96 hex characters). Truncated version of SHA-512, used in TLS 1.2+.
- SHA-512 — 512-bit hash (128 hex characters). Maximum security for sensitive data integrity.
How It Works
Type or paste text and all four hashes are generated simultaneously using your browser's Web Crypto API — the same cryptographic engine used by HTTPS. No JavaScript hashing libraries needed; the computation runs in native code for maximum speed and security.
Use Cases
Hash generators are essential for file integrity verification, password storage (with salting), digital signatures, blockchain, data deduplication, and checksum comparisons. Developers use them daily to verify downloads, compare file contents, and debug API authentication.
Privacy & Security
Text is processed in your browser using the Web Crypto API. This makes it suitable for hashing sensitive data like passwords, API keys, and private documents.
