SHA-384 Hash Generator
Produce a SHA-384 digest of UTF-8 text with the browser Web Crypto API. The result contains 96 lowercase hexadecimal characters.

How to use
- Paste a message or load a text file.
- Run the tool to calculate its 384-bit digest.
- Compare the full 96-character value with the expected SHA-384 reference.
- Copy or download the output for a release record.

A 96-character SHA-384 hex digest
Use the exact SHA-2 variant
SHA-384 is common in systems that specify a 384-bit SHA-2 digest. It is not enough to calculate SHA-512 and cut off characters: the standardized SHA-384 algorithm uses its own initial values. When comparing a value from another application, confirm that both sides select SHA-384, encode text the same way, and include the same line endings. This tool shows the digest in lowercase hexadecimal form.
A useful workflow is to keep the source text and expected digest together in a test fixture. If the values disagree, inspect invisible characters before changing algorithms. This page is designed for text, not raw binary file bytes. It does not make a message confidential or prove its origin. The browser’s Web Crypto API performs the operation locally, and the site has no hash-processing server. The NIST SHA-2 standard defines SHA-384 alongside the other SHA-2 functions.
When documenting an expected value, write down whether the source was copied from a terminal or a file. Terminal commands often append a newline, while an editor selection may not. Reproducing the input bytes is usually more important than repeatedly recalculating the hash.
Frequently asked questions
How is SHA-384 related to SHA-512?
Both are SHA-2 algorithms, but SHA-384 uses its own initialization and output definition.
Is it the same as SHA3-384?
No. SHA-3 is a different algorithm family.
Can this verify who sent a message?
No. Use a verified signature or HMAC for sender authentication.
Does the tool upload the message?
No. Web Crypto processes it in your browser worker.
