What is the relationship between SHA-384 and SHA-512?
SHA-384 is computed using the SHA-512 algorithm with different initial constants, then truncated to 384 bits. On 64-bit hardware it runs at the same speed as SHA-512 because the underlying math is identical. The truncation provides resistance against length-extension attacks that affect plain SHA-512, which is why some protocols prefer SHA-384 even though its hash is shorter.
When should I prefer SHA-384 over SHA-256?
Choose SHA-384 when you need a higher security margin - for example, long-lived digital signatures, top-secret data classification levels mandated by NSA Suite B, or HMAC keys that must remain secure for decades. SHA-384 also performs better than SHA-256 on 64-bit CPUs because its underlying SHA-512 design uses 64-bit operations natively. For short-lived tokens, SHA-256 is usually fine.
How long is the SHA-384 hash output?
SHA-384 produces 384 bits of output, shown as 96 hexadecimal characters. That is one and a half times the length of SHA-256 and three quarters the length of SHA-512. The output is fixed regardless of input size. If you store hashes in a database, allocate at least a 96-character column for hex or 64 characters for Base64 encoding.
Is SHA-384 protected against length-extension attacks?
Yes. Because its output is a truncation of SHA-512's internal state, an attacker cannot use the published hash as the starting point to compute the hash of secret-plus-extra-data. Plain SHA-256 and SHA-512 are vulnerable to that trick when used naively for keyed authentication, which is why HMAC exists. SHA-384, SHA-512/224, and SHA-512/256 sidestep the issue by truncating the output.
Does the calculation happen entirely in my browser?
Yes. SHA-384 is implemented in client-side JavaScript or via the browser Web Crypto API, so the input string is never transmitted. You can paste sensitive identifiers, draft documents, or test material without worrying about server logs or analytics capturing the content. Only the page assets themselves are loaded from our servers; the hashing itself happens privately on your machine.
Can SHA-384 be used for password hashing?
No. Like every member of the SHA-2 family it is far too fast - billions of candidate guesses per second on a single GPU. Use bcrypt, scrypt, or Argon2 for passwords because they are deliberately slow and include built-in salting. SHA-384 is excellent for digital signatures, certificate fingerprints, and HMAC, but it should never be your sole defense for stored credentials.
