Calculate SHA-384

What is SHA-384?

SHA-384 is a member of the Secure Hash Algorithm (SHA) family, designed by the National Security Agency (NSA). It is a cryptographic hash function that produces a 384-bit (48-byte) hash value, also known as a message digest. SHA-384 is a one-way function, meaning it's computationally infeasible to reverse the process and obtain the original input from the hash value.

Key Properties of SHA-384:

• Preimage Resistance: Given a hash value, it's extremely difficult to find any input that produces that hash.
• Second Preimage Resistance: Given an input, it's difficult to find a different input that produces the same hash value.
• Collision Resistance: It's difficult to find two different inputs that produce the same hash value.

SHA-384 is often used in applications where security and data integrity are critical, such as:

• Password storage: Hashing passwords before storing them protects against unauthorized access.
• Digital signatures: Creating unique signatures for files to verify authenticity and prevent tampering.
• Data integrity checks: Comparing the SHA-384 hash of a file before and after transmission to detect any data corruption.

SHA-384 vs. Other Hash Functions

SHA-384 is similar to other SHA algorithms like Calculate SHA-224, Calculate SHA-256, and Calculate SHA-512 but differs in the length of the hash value it produces. It is considered more secure than older algorithms like MD5 because of its larger hash size and more robust design.
