About Hash Functions
Cryptographic hash functions produce a fixed-size output (digest) from any input. They are one-way functions, meaning you cannot reverse the hash to recover the original text. Hashes are widely used for data integrity verification, password storage, and digital signatures.
Supported Algorithms
- MD5 (128-bit) — Fast but cryptographically broken. Use only for checksums, not security.
- SHA-1 (160-bit) — Deprecated for security use. Still seen in legacy systems and Git.
- SHA-256 (256-bit) — Part of SHA-2 family. Widely used and recommended for most purposes.
- SHA-512 (512-bit) — Longer output from SHA-2 family. Higher security margin, may be faster on 64-bit systems.
All hashing is performed in your browser using the Web Crypto API (SHA) and a JavaScript implementation (MD5). No data is sent to any server.
