SHA-384 Hash Generator

SHA-384 is a cryptographic hash function in the SHA-2 family, defined in FIPS 180-4. It is a truncated version of SHA-512 that uses a different initial hash value, producing a 384-bit (48-byte) digest. It provides strong collision resistance and is widely used in TLS certificates, digital signatures, and integrity verification.

SHA-256 produces a 256-bit (32-byte) digest using 32-bit word operations, while SHA-384 produces a 384-bit (48-byte) digest using 64-bit word operations inherited from SHA-512. On 64-bit processors, SHA-384 can actually be faster than SHA-256 because it operates on native word sizes. SHA-384 also offers a higher security margin against collision attacks.

SHA-384 is commonly required in government and enterprise environments that follow CNSA (Commercial National Security Algorithm) guidelines. It is the default hash in TLS 1.3 cipher suites using ECDSA with P-384 curves. Use it when you need stronger collision resistance than SHA-256 but do not need the full 512-bit output of SHA-512.

SHA-384 always produces a fixed 384-bit output regardless of input size. When represented as a hexadecimal string, this is exactly 96 characters. In Base64 encoding, the output is 64 characters.
