What Is a SHA-384 Hash?

SHA-384 (Secure Hash Algorithm 384) is a cryptographic hash function from the SHA-2 family designed by the NSA. It produces a fixed 384-bit (48-byte) hash value — typically rendered as a 96-character hexadecimal string. SHA-384 is a truncated version of SHA-512, meaning it uses the same internal 64-round computation but starts with different initial values and outputs fewer bits.

Because it inherits SHA-512's 64-bit word architecture, SHA-384 often runs faster on 64-bit processors than SHA-256 while delivering a larger digest — making it an excellent middle ground between performance and security.

Why SHA-384 Matters for Security

Hash functions are the backbone of modern data integrity and authentication. SHA-384 is widely used in:

  • TLS/SSL certificates — many certificate authorities default to SHA-384 signatures.
  • Code signing — software publishers verify binaries haven't been tampered with.
  • Digital signatures — ECDSA with P-384 curves pairs naturally with SHA-384.
  • Data integrity checks — verify file downloads, backups, and database records.

Its 384-bit output provides 192 bits of collision resistance, making brute-force attacks computationally infeasible with current and foreseeable technology.

How to Use Our Free SHA-384 Generator

  1. Enter or paste the text you want to hash into the input field.
  2. Click Generate to compute the SHA-384 hash instantly.
  3. Copy the resulting 96-character hex string for your records.

No data is sent to external servers — the hash is computed securely and instantly.

Common Use Cases

  • File verification — compare SHA-384 checksums before and after transfer to ensure nothing changed.
  • Password storage — though dedicated algorithms like bcrypt are preferred, SHA-384 is used in legacy systems.
  • API authentication — HMAC-SHA384 secures webhook signatures and API tokens.
  • Blockchain & cryptography — used in various protocols requiring strong collision resistance.
  • Compliance — meets NIST FIPS 180-4 requirements for government and enterprise systems.

SHA-384 vs. Other Hash Algorithms

SHA-384 vs. SHA-256

SHA-256 outputs 256 bits (64 hex chars) while SHA-384 outputs 384 bits (96 hex chars). On 64-bit systems, SHA-384 is often faster because it uses SHA-512's optimized 64-bit operations. Choose SHA-384 when you need a stronger digest without sacrificing speed.

SHA-384 vs. SHA-512

Both use the same core algorithm, but SHA-384 truncates the output from 512 to 384 bits with different initialization vectors. If you don't need the full 512-bit digest, SHA-384 is more compact while still highly secure.

SHA-384 vs. MD5

MD5 is broken — it's vulnerable to collision attacks and should never be used for security. SHA-384 provides vastly superior security. Only use MD5 for non-security checksums.

Best Practices

  • Always use SHA-384 or stronger for any security-sensitive application.
  • For password hashing, prefer bcrypt or Argon2 over raw SHA hashes.
  • Combine SHA-384 with HMAC for message authentication (HMAC-SHA384).
  • Store hashes in lowercase hex for consistency.
  • Verify checksums immediately after file transfers.

Frequently Asked Questions

Is SHA-384 secure?

Yes. SHA-384 is part of the SHA-2 family and provides 192 bits of collision resistance. No practical attacks have been found against it, and it remains approved by NIST for all security applications.

What is the difference between SHA-384 and SHA-512?

SHA-384 is essentially SHA-512 with different initial hash values and a truncated output (384 bits instead of 512). The core algorithm and number of rounds are identical.

Can SHA-384 be reversed?

No. SHA-384 is a one-way function — it's computationally infeasible to recover the original input from the hash output. That's what makes it useful for security applications.

When should I use SHA-384 over SHA-256?

Use SHA-384 when you need a larger security margin, when working with 64-bit systems (where it's often faster), or when pairing with ECDSA P-384 curves in TLS and digital signatures.
