SHA384 Hash Generator

Generate SHA384 hashes. Enhanced security with 384-bit output for digital signatures and high-security protocols.

Know more about SHA384 (Secure Hash Algorithm 384-bit)

SHA384 is part of the SHA-2 family and generates a 384-bit (48-byte) digest. It offers a larger safety margin than SHA256 while preserving excellent performance and broad platform support.

Use HMAC-SHA384 when you need both integrity and authenticity. HMAC combines your secret key with the hash, making it ideal for API signatures, webhook validation, and secure message authentication.

This tool runs entirely in your browser, leveraging modern Web Crypto APIs. Your input never leaves your device. Click “Secret Key” to reveal optional HMAC controls, then press “Generate” to produce the digest instantly.

  • Digest length: 96 hexadecimal characters (384 bits).
  • Output format: lowercase hexadecimal (UTF-8 input).
  • Best for: high-assurance systems, digital signatures, integrity checks.

Tip: Prefer SHA384 for long-lived credentials or compliance-focused environments; use SHA256 as a general default when longer digests aren’t required.

Enhanced Security

SHA384 provides additional security margin with longer digest lengths, commonly used in digital signatures and high-security protocols.

What is SHA-384?

SHA-384 is a truncated variant of SHA-512 that produces 384-bit digests. It retains the security properties of SHA-2 with a shorter output, making it attractive for certain protocols and signature schemes.

HMAC-SHA-384

HMAC with SHA-384 offers strong message authentication and integrity. It is suitable for request signing, secure cookies, and verifying data in transit when a shared secret is available.

Choosing between SHA-256, SHA-384, and SHA-512

  • Use SHA-256 for general purposes and broad ecosystem compatibility.
  • Use SHA-384 for shorter digests with strong security margins.
  • Use SHA-512 when larger digests or 64-bit optimization is preferred.

FAQs

When should I choose SHA-384?

SHA-384 is a strong choice when you want higher security margins than SHA-256 with good performance, especially in systems optimized for 64-bit processing.

Is HMAC-SHA-384 recommended?

Yes. HMAC with SHA-384 provides authenticity and integrity, resisting length-extension attacks. Use it for signing requests and validating messages.

Is SHA-384 a truncated SHA-512?

SHA-384 uses different initial constants and produces a 384-bit digest. It is related to SHA-512 but not simply a truncation.
