SHA3-384 Hash Generator

Question 1

How does this SHA3-384 hash generator work?

Accepted Answer

This tool uses the SHA3-384 (Keccak) algorithm to generate hash values from your input text. As you type, the SHA3-384 hash is calculated in real-time and displayed instantly. The hash changes completely even with small input modifications, which is a key characteristic of cryptographic hash functions.

Question 2

Is my data secure and private?

Accepted Answer

Yes, absolutely. All SHA3-384 hash generation happens locally in your browser. Your input text is never sent to any server or stored anywhere. The processing is completely offline, ensuring your data remains private and secure.

Question 3

What is SHA3-384 and when should I use it?

Accepted Answer

SHA3-384 is NIST's standardized version of the Keccak hash function, which won the SHA-3 competition. It produces a 384-bit (48-byte) hash value, displayed as a 96-character hexadecimal string. SHA3-384 uses a modified version of the Keccak algorithm with different padding rules (multi-rate padding). If you need to follow the NIST standard, use SHA3-384. However, if you need the original Keccak algorithm, use our Keccak-384 tool instead, as they produce different hash values.

Question 4

Is SHA3-384 secure for passwords or sensitive data?

Accepted Answer

While SHA3-384 is cryptographically secure, for password hashing it should always be used with proper salting and multiple iterations (like in PBKDF2) or preferably with specialized password hashing algorithms like bcrypt or Argon2. For general cryptographic purposes, SHA3-384 remains secure and is suitable for many security applications.

Question 5

What are valid use cases for SHA3-384?

Accepted Answer

SHA3-384 is suitable for applications that need to follow the NIST standard, including digital signatures, message authentication codes (with a key), and secure data fingerprinting. It's particularly useful in high-security systems that need an alternative to SHA-2 algorithms or where NIST compliance is required. The longer output size makes it appropriate for applications requiring enhanced security. Note that if you need compatibility with the original Keccak-384 algorithm, you should use our Keccak-384 tool instead.

Question 6

Can I hash large amounts of text?

Accepted Answer

Yes, this tool can handle text of various sizes. However, very large inputs may cause browser performance issues. The tool works best with typical text inputs up to several thousand characters. For very large files, consider using command-line tools or server-side processing.
