SHA-384 hash generator
Computes SHA-384 from the SHA-2 family in FIPS 180-4, common in Subresource Integrity values and elliptic-curve TLS certificates.

Processing and privacy: The result is calculated inside your browser and your data is not sent to any server.
How to use it
- Enter text or bytes and input type.
- The result appears straight away and updates as you edit.
- Copy the result, or copy a link that keeps the same values to share it.
How it is calculated
It runs the SHA-512 algorithm with 64-bit words and 80 rounds on 1024-bit blocks, but with different initial values, and keeps the first 384 bits.
Example
Inputs: Input type = Text (UTF-8). Result: SHA-384 digest (hex): cb00753f45a35e8bb5a03d699ac65007272c32ab0eded1631a8b605a43ff5bed8086072ba1e7cc2358baeca134c825a7; Input size: 3 bytes; Digest length: 384 bits.

Limits and caveats
- The digest covers the text exactly as typed: a trailing space or newline changes it completely, and line breaks count as LF.
- An integrity value for a JavaScript file is computed over the file bytes, so paste its content complete and unchanged.
Questions about this tool
How do I write an integrity value from the result?
Write sha384- followed by the Base64 output, so the attribute reads integrity="sha384-" plus the output on a script or link tag.
How does SHA-384 differ from SHA-512?
They share one algorithm, but SHA-384 starts from different initial values and truncates the output to 384 bits.
Why is SHA-384 a little slower here?
It works on 64-bit words emulated with BigInt in JavaScript. That does not affect the correctness of the result.
