Compute a SHA-256 hash of any string — for verifying checksums, comparing values, generating deterministic IDs or learning how hashing works. The hash appears as you type, alongside SHA-1, SHA-384 and SHA-512.
Hashing uses the browser's built-in Web Crypto API; the input never leaves your device. To hash a file rather than text, use the File Checksum Verifier.
No. It is a one-way function. Matching a hash to an input is only possible by guessing inputs, which is why long random passwords are safe even when only their hash leaks.
Yes, it is the current standard for integrity checks, TLS certificates and Bitcoin. SHA-1 and MD5 are not.
