SHA-256 digest
The SHA-256 generator is the default choice for token fingerprints, integrity checks, and security tests. Digests are computed locally through the Web Crypto API with no sign-up or server upload.
UTF-8 source string
Paste a secret, canonical string, or JSON fragment—the hex appears instantly. Data never leaves the tab.
The same input always yields the same digest on any machine using this tool.
Hex output
Sixty-four hex characters map to 256 bits—common in logs and If-None-Match headers.
Still use proper salted password storage; hashing a string is not a full credential vault.
