What is HMAC-SHA384?

HMAC-SHA384 is a high-security message authentication code based on the SHA-384 hash function. It is part of the NSA's Suite B Cryptography for protecting classified information.

Security Note

SHA-384 is a truncated version of SHA-512 and is inherently resistant to length extension attacks. HMAC-SHA384 is extremely robust and suitable for high-security communications and data integrity checks.
