Online SHA-384 Hash Generator
SHA-384 is a member of the SHA-2 family that produces a 384-bit hash value (96 hexadecimal characters). It is built on SHA-512, making it very strong for high-security needs.

About SHA-384
SHA-384 is one of the hash functions in the SHA-2 family, designed by the National Security Agency (NSA). The "384" indicates the output length: 384 bits, shown as 96 hexadecimal characters, regardless of input length.
How it works: SHA-384 is actually a truncated version of SHA-512. It uses 64-bit operations and processes data in 1024-bit blocks through 80 compression rounds, with different initial hash values than SHA-512, then truncates the output to 384 bits. Using 64-bit arithmetic makes it very efficient on modern 64-bit processors.
SHA-384 is used where a larger security margin than SHA-256 is desired, such as TLS, high-grade digital certificates, and code signing. A notable benefit: its truncation makes it resistant to length-extension attacks that can affect raw SHA-256/SHA-512.
FAQ
How is SHA-384 related to SHA-512?
SHA-384 uses the SHA-512 core algorithm (64-bit operations, 1024-bit blocks) but with different initial hash values and output truncated to 384 bits. So the two are very similar internally.
Is SHA-384 secure?
Yes. SHA-384 is considered very secure and offers a larger security margin than SHA-256. There are no known practical collision attacks against the SHA-2 family.
Is my data sent to a server?
No. SHA-384 is computed in your browser using the built-in Web Crypto API. Your data never leaves your device.
When should I use SHA-384 instead of SHA-256?
Use SHA-384 when you want a larger security margin or work on 64-bit systems where it can be faster, and when resistance to length-extension attacks matters. For general needs, SHA-256 is sufficient.
