How to generate a SHA-3-384 hash

1. Enter your text

   Paste or type any plain text into the Text field — up to 200,000 characters. This is the string that will be hashed using the SHA-3-384 algorithm.

2. Choose hex case

   Select lower case (a–f, the default) or UPPER CASE (A–F) for the hexadecimal output. Both are valid — choose based on what your downstream system expects.

3. Run and copy the hash

   Press Run. The SHA-3-384 hash is computed server-side and returned as a hexadecimal string. Click Copy to grab it. SHA-3-384 uses the Keccak sponge and produces a 384-bit digest. It is suitable when you want SHA-3's security properties with a longer output.

4. Verify or compare

   To verify a file's integrity, hash it as text and compare the output to the published checksum. To check two strings are equal without revealing the originals, hash both and compare the digests — identical digests mean identical inputs.
