SHA384 Decrypt
Reverse a SHA-384 hash by brute force — try every short combination of characters, entirely in your browser, to recover the original text.
Input
~1.7 million combinations — may take a while.
Split the search across browser threads to check more combinations per second.
Result
Paste a hash and press Start search. The search runs entirely in your browser.
Guides
Paste a SHA-384 hash and this tool tries to recover the original text by brute force — testing every short combination of characters until one produces a matching hash. It runs entirely in your browser: the search happens on your own machine, and nothing is uploaded.
Can you actually "decrypt" a SHA-384 hash?
No — and it's worth being clear about why. A hash is not encryption. Encryption is reversible with a key; hashing is a one-way function designed so the original can't be recovered from the output. There is no "decrypt" operation and no key.
What this tool does instead is guess. It hashes candidate strings one after another and checks whether any of them matches your hash. If the original was short and simple, a guess will find it quickly. If it wasn't, no tool — this one included — can reverse it.
Then when will it find something?
When the original input was short and drawn from a small set of characters. The number of combinations is the alphabet size raised to the length, so it grows explosively:
- lowercase, up to 4 characters → about 475,000 tries — instant.
- lowercase + digits, up to 5 → about 60 million — a few seconds to a minute.
- add uppercase and symbols, or go past 6 characters → billions or trillions — not feasible in a browser.
SHA-384's own strength is not what limits this tool — the same brute-force search speed applies regardless of which hash algorithm you're reversing. The tool shows an estimate of the search size as you change the settings, so you know before you start whether it can finish.
What is SHA-384, exactly?
SHA-384 is a member of the SHA-2 family, standardised in FIPS 180-4. It is SHA-512 run with different initial values and its output truncated to 384 bits, which is why its hex digest is 96 characters rather than SHA-512's 128. Because it is built on the 64-bit SHA-512 core, it is often faster than SHA-256 on 64-bit hardware, and it is the hash paired with P-384 in the TLS and Suite B cipher suites.
How do I use it?
- Paste the SHA-384 hash (96 hex characters).
- Tick the character sets the original might contain.
- Set the maximum length to try and a time limit.
- Press Start search. Progress is shown live, and you can stop at any time.
Raise the Web workers slider to split the search across your CPU's threads — more workers check more combinations per second, each on a disjoint slice of the search space.
Is this legal / what should I use it for?
Reversing hashes of data you own or are authorised to test — recovering your own forgotten value, checking whether a password you chose is weak enough to be cracked, or CTF and learning exercises. Don't use it against data you have no right to.
Is my hash private?
Yes. Everything runs client-side in a background thread in your browser. The hash you paste and any recovered text never leave your device — there is no server involved, unlike some online "hash decrypter" tools that send your hash to a lookup database.
What if my hash isn't SHA-384, or I need to generate one?
For SHA-224 use SHA224 Decrypt; for SHA-256 and SHA-512, SHA256 Decrypt and SHA512 Decrypt. For MD5 or SHA-1, use the MD5 Decrypt tool, which offers a selector. To generate a hash instead of reversing one, use the SHA Hash Generator, which includes SHA-384.
