SHA-384 generator
What Is SHA-384?
SHA-384 is the 384-bit member of the SHA-2 family — SHA-512 run with different initial values and truncated to 384 bits (96 hex characters). It is the default hash in many TLS 1.3 cipher suites and government standards.
Where SHA-384 Shows Up
TLS certificates, DNSSEC, and protocols that want more than 256 bits of security margin without the full 512-bit output. If a specification names SHA-384, it usually means "serious cryptography" — this generator gives you exactly that digest.
Performance Note
Like SHA-512, SHA-384 is optimized for 64-bit processors and can actually outperform SHA-256 on modern hardware despite the larger digest.
How to Use the SHA-384 Hash Generator
SHA-384 produces a 384-bit digest using the SHA-512 compression function with its own initial values, then truncating the result — a trusted choice for TLS certificates and digital signatures.
- Type the content for SHA-384 — the truncated SHA-512 variant widely used in TLS certificates.
- Click the hash button to compute the 384-bit digest.
- Copy the 96-character hexadecimal result for certificate fingerprints, code signing or signature schemes.
Example
Hashing the word hello with SHA-384 always produces 59e1748777448c69de6b800d7a33bbfb9ff1b463e44354c3553bcdb9c666fa90125a3c79f90397bdf5f6a13de828684f — try it and you will see the identical 96 characters.
Frequently Asked Questions
Is SHA-384 just the first 96 characters of SHA-512?
No. SHA-384 starts from different initial values, so its digests are completely different from truncated SHA-512 output of the same input.
Where is SHA-384 used?
It is the digest paired with 384-bit elliptic curves in TLS, appears in many CA certificates, and is approved in the NSA Suite B cryptographic guidance.
Why pick SHA-384 instead of SHA-256?
It offers a higher security margin with 192-bit collision resistance, while staying smaller than a full 512-bit digest — a sweet spot for certificates and signatures.
