How to Use the SHA-384 Hash Generator

Type or paste your input string into the field.

The SHA-384 hash is computed instantly and displayed as a 96-character hexadecimal string.

Copy the hash for your application or verification workflow.

What Is SHA-384?

SHA-384 is a member of the SHA-2 family, defined in FIPS 180-4. It is structurally derived from SHA-512 — using different initialization constants and truncating the output to 384 bits (48 bytes), producing a 96-character hex string. SHA-384 is used in TLS cipher suites, digital certificate signing, and protocols that require a larger digest than SHA-256 but smaller than the full 512-bit output. It benefits from SHA-512's 64-bit word operations, which can be faster than SHA-256 on 64-bit hardware for large inputs.

When to Use This Tool

TLS and certificate workflows — SHA-384 appears in several TLS 1.2 and 1.3 cipher suites and certificate signature algorithms (e.g., ECDSA with SHA-384).

High-security digest requirements — When a larger output than SHA-256 is required but the full 512-bit SHA-512 output is unnecessary.

Government and compliance contexts — NIST and various compliance frameworks specify SHA-384 for certain cryptographic operations.

Subresource Integrity (SRI) — SHA-384 is commonly used for HTML <script> and <link> integrity attributes to verify CDN-served assets.

FAQ

Answers about this tool and how your data is handled.

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

SHA-384 uses different initialization constants and truncates the SHA-512 output to 384 bits. The underlying compression function is identical. SHA-512 provides a larger output and marginally stronger collision resistance.

Is SHA-384 faster or slower than SHA-256?

On 64-bit hardware, SHA-384 (and SHA-512) can be faster than SHA-256 for large inputs because they operate on 64-bit words rather than 32-bit words. For short inputs the difference is negligible.

Is SHA-384 suitable for password hashing?

No. Use bcrypt, Argon2, or scrypt for passwords. SHA-384 is designed for data integrity and digital signatures.

Does this tool send my data to a server?

No. Hashing runs entirely in your browser. Nothing is uploaded.

What is the output length of a SHA-384 hash?

Always 96 hexadecimal characters, representing 384 bits.
