🔐 SHA-384 Hash Calculator – Generate Secure Message Digests

The SHA-384 Hash Calculator is a powerful cryptographic tool that generates SHA-384 hash values from text input or file content. This online utility provides a simple way to create secure hash digests for data verification, integrity checking, and high-security applications.

This guide explains what SHA-384 hashing is, how it works, and walks you through using our free online SHA-384 hash calculator tool to generate and verify hash values.

📘 What Is SHA-384 Hashing?

SHA-384 (Secure Hash Algorithm 384) is a cryptographic hash function that belongs to the SHA-2 family, developed by the National Security Agency (NSA) and published by the National Institute of Standards and Technology (NIST) in 2001. It produces a 384-bit (48-byte) hash value, typically represented as a 96-character hexadecimal string.

SHA-384 is actually a truncated version of SHA-512 with different initial values. It provides a higher security level than SHA-224 or SHA-256, making it suitable for applications requiring enhanced security while maintaining good performance.

A hash function takes input data of arbitrary size and produces a fixed-size output (the hash or digest) that is unique to that input. Even a small change in the input produces a completely different hash value, making hash functions useful for data integrity verification and security applications.

🔒 Security Characteristics of SHA-384

SHA-384 offers robust security features that make it suitable for high-security applications:

  • 🛡️ Strong collision resistance - It's computationally infeasible to find two different inputs that produce the same hash output
  • 🛡️ Pre-image resistance - Given a hash value, it's extremely difficult to find an input that would produce that hash
  • 🛡️ Second pre-image resistance - Given an input and its hash, it's extremely difficult to find another input that produces the same hash
  • 🛡️ Avalanche effect - A small change in the input produces a significantly different hash output
  • 🛡️ Enhanced security margin - With 384 bits of output, SHA-384 provides a higher security level than shorter hash functions

SHA-384 is considered secure for all current applications and is recommended for systems requiring a high level of security.

🌟 Examples of SHA-384 Hash Values

Here are some examples of text strings and their corresponding SHA-384 hash values:

  • Empty string: 38b060a751ac96384cd9327eb1b1e36a21fdb71114be07434c0cc7bf63f6e1da274edebfe76f65fbd51ad2f14898b95b
  • "hello": 59e1748777448c69de6b800d7a33bbfb9ff1b463e44354c3553bcdb9c666fa90125a3c79f90397bdf5f6a13de828684f

Note that even small changes in the input text produce completely different hash values, demonstrating the "avalanche effect" characteristic of hash functions.

🔄 SHA-384 vs. Other Hash Functions

How does SHA-384 compare to other hash functions?

  • 🔹 SHA-384 vs. SHA-256: SHA-384 produces a larger hash (384 bits vs. 256 bits) and offers a higher security margin, while SHA-256 is slightly faster but provides less security.
  • 🔹 SHA-384 vs. SHA-512: SHA-384 is a truncated version of SHA-512 with different initial values. It provides nearly the same security level with a slightly smaller output size.
  • 🔹 SHA-384 vs. MD5: SHA-384 is significantly more secure than MD5, which has been broken and should not be used for security purposes.
  • 🔹 SHA-384 vs. SHA-1: SHA-384 is much more secure than SHA-1, which has been deprecated due to vulnerabilities.
  • 🔹 SHA-384 vs. SHA-3: SHA-3 uses a different internal structure (sponge construction) and is designed to be more resistant to certain types of attacks, but SHA-384 remains secure for all current applications.

⚠️ Best Practices for Using SHA-384
