SHA-1 digest
The SHA-1 generator computes a 160-bit digest via Web Crypto. NIST deprecated SHA-1 for signatures, yet it remains in old Git tooling, APIs, and compatibility paths. Compare output easily with docs and integration logs.
UTF-8 source string
UTF-8 text is hashed in the browser without uploading files. Long inputs stream client-side.
Match the other party’s encoding when comparing with documentation examples.
Hex output
Forty hex characters represent the full SHA-1 output. Paste into tickets or unit tests.
New projects should prefer SHA-256 from the same toolkit.
