How to Use

  1. 1Type or paste your text into the input box above.
  2. 2Your hash digest appears instantly — no page reload needed.
  3. 3Toggle UPPERCASE / lowercase to change the hex output format.
  4. 4Click the copy icon to copy the hash to clipboard, or use Save to save as .txt.
  5. 5Paste an expected hash into the Verify field to check for a match.
  6. 6How to verify high-security TLS connections: when your organization requires FIPS 140-2 validated cryptography, compute SHA-384 hashes for CA certificate verification and secure channel establishment.
  7. 7How to use SHA-384 for classified document integrity: compute SHA-384 of sensitive documents and store the 96-character hash separately. Verify periodically by recomputing and comparing.
  8. 8How to compare SHA-384 with SHA-256 output: input the same text in both tools. SHA-384's 96-character output provides 192-bit security vs SHA-256's 64-character 128-bit security — 50% more output for 50% more security.
  9. 9How to generate SHA-384 for blockchain applications: some high-security blockchain platforms use SHA-384 for block hashing and transaction verification. Input your block data and use the hash output as the block identifier.
  10. 10How to format SHA-384 hashes for compliance reporting: toggle uppercase/lowercase to match your compliance documentation standard, then copy or save the hash for audit records.

Frequently Asked Questions

What is SHA-384?

∨
SHA-384 is a truncated SHA-512 producing 384-bit (96 hex) hashes. With 192-bit security against collisions, it suits the highest-security applications including government classified data and military communications.

Why use SHA-384 instead of SHA-256?

∨
SHA-384 offers 192-bit security vs SHA-256's 128-bit, providing significantly larger security margin against future cryptanalysis and quantum computing advances.

Is SHA-384 quantum-resistant?

∨
SHA-384 provides stronger resistance to Grover's algorithm than SHA-256. A quantum computer would effectively reduce SHA-384 to 192-bit security (still very strong) vs SHA-256's 128-bit.

Where is SHA-384 used?

∨
In high-security TLS connections, military-grade communication systems, classified document signing, and blockchain projects prioritizing long-term security over performance.

SHA-384 vs SHA-256 performance?

∨
SHA-384 inherits SHA-512's 64-bit word processing, making it faster than SHA-256 on 64-bit CPUs despite producing larger hashes (96 vs 64 hex chars).

How many hex characters does SHA-384 produce?

∨
SHA-384 produces a 384-bit hash displayed as 96 hexadecimal characters — 32 characters more than SHA-256 and 32 fewer than SHA-512.

Is SHA-384 FIPS 140-2 compliant?

∨
Yes, SHA-384 is approved by FIPS 140-2 for use in US government cryptographic modules. It's included in the FIPS 180-4 standard (Secure Hash Standard).

When should I choose SHA-384 over SHA-512?

∨
Choose SHA-384 when you want SHA-512's security properties (64-bit word processing, faster on 64-bit CPUs) but need a shorter 96-character output. It's also appropriate when protocol compatibility requires exactly 384-bit hashes.

Does SHA-384 support streaming?

∨
Yes, SHA-384 inherits SHA-512's streaming capability, allowing large data to be hashed incrementally without loading everything into memory.

What is the internal structure of SHA-384?

∨
SHA-384 uses the same SHA-512 compression function with a different initial hash value and truncated (384-bit) output. It processes data in 1024-bit blocks through 80 rounds.

Is SHA-384 suitable for password hashing?

∨
Like all SHA-2 variants, SHA-384 is not designed for password hashing — it's too fast. Use bcrypt, Argon2id, or scrypt for passwords.

What real-world standards reference SHA-384?

∨
NSA's Suite B cryptography specifies SHA-384 for classified information up to TOP SECRET level. NIST SP 800-57 recommends SHA-384 for 192-bit security lifetime through 2030+.
