Hash Generator — SHA-256, SHA-512, Keccak256, SHAKE & MD5
Generate cryptographic hashes from text or hex data. Supports MD5, SHA-1, SHA-256, SHA-384, SHA-512, Keccak-256, Keccak-512, and SHAKE-128/256 with adjustable output length. Everything runs in your browser — no data is sent to any server.
Input length: 13 bytes
SHA-1 and MD5 are cryptographically broken — do not use for security purposes.
Keccak-256 is the hash used by Ethereum (not the same as NIST SHA3-256).
SHAKE-128 / SHAKE-256 are SHA-3 extendable-output functions (XOF) — unlike fixed-length digests they can produce any output size; pick the output length above.
