Hash & Checksum Generator

Compute SHA-256, SHA-384, and SHA-512 cryptographic digests locally for UTF-8 text and files with case-insensitive verification.

Integrity Checksums Only — NOT for Password Hashing · Zero Bytes Uploaded

SHA-256, SHA-384, and SHA-512 are fast cryptographic digests designed for checksums and tamper detection — never store passwords with raw SHA hashes (use Argon2id, bcrypt, or scrypt on your server). All hashing executes locally in browser memory via Web Crypto.

Expected SHA-256, SHA-384, or SHA-512 Checksum (case-insensitive)

Automatically matches SHA-256 (64 hex chars), SHA-384 (96 hex chars), or SHA-512 (128 hex chars), ignoring case and surrounding spaces.
