Welcome to the most flexible hash generator on the web! This online SHAKE-128 Hash Generator is a powerful tool designed to create secure cryptographic hashes of any length you need. Get started in seconds—just paste your text, define your output size, and get your hash.
What is the SHAKE-128 Hash Generator?
This tool is a simple, browser-based utility that uses the SHAKE-128 algorithm. SHAKE-128 is a member of the modern SHA-3 family of cryptographic functions. What makes it special is that it’s an “eXtendable-Output Function” (XOF). Unlike fixed-length hashes (like SHA-256), this allows you to specify exactly how long you want the resulting hash to be, making it incredibly versatile for a wide range of advanced cryptographic applications.
How to Use This SHAKE-128 Hash Generator
Using the generator is incredibly straightforward. Here’s how:
- Enter Your Text: In the first text area, type or paste the text, string, or data you want to hash.
- Specify Output Length: In the “Output Length (in bits)” field, enter the size of the hash you need. For example, enter
256for a 256-bit hash. - Generate Hash: Click the “Generate Hash” button.
- Copy Your Hash: Your unique, custom-length SHAKE-128 hash will instantly appear in the “SHAKE-128 Hash” box. You can then use the “Copy Hash” button to save it to your clipboard.
Example
Here’s a practical example of how the tool works.
- Input Text:
Hello, this is a test! - Output Length (in bits):

Features of This SHAKE-128 Hash Generator
- Variable Output Length: The key feature! You are in complete control and can specify the exact bit length for your output hash.
- 100% Client-Side: Your security is our priority. This tool runs entirely in your browser. No data is ever sent to our servers, ensuring your input is completely private.
- Instant Generation: The underlying algorithm is highly efficient, providing your custom hash in a fraction of a second.
- Easy to Use: A clean, no-clutter interface with “Copy” and “Clear” buttons for a fast workflow.
- Based on SHA-3: Built on the modern, secure, and NIST-approved Keccak (SHA-3) algorithm.
Use Cases for SHAKE-128
Why would you need a variable-length hash? Here are a few common applications:
- Key Derivation: Generating cryptographic keys of a specific, non-standard length from a single password or master key.
- Randomized Hashing: Creating unique hash-based signatures or fingerprints where the length can be adjusted.
- Pseudo-Random Number Generation: Can be used as a high-quality, seedable random number generator (PRNG) for cryptographic purposes.
- Stream Ciphers: Serves as a core component in building secure stream ciphers.
- Data Masking: Generating variable-length “fingerprints” for data to use in databases or protocols that have specific field-size limits.
Pro-Tips
- Bits vs. Bytes: Remember that the output length is in bits. If you need a 64-character hexadecimal string, you need a 256-bit hash (since 1 hex character = 4 bits; 64 * 4 = 256).
- Security Strength: The “128” in SHAKE-128 refers to its 128-bit security strength (against collision attacks, etc.), not its output length. You can generate a 1000-bit hash, but it still provides 128 bits of security.
- Use Clear: The “Clear” button is the fastest way to reset all fields and start a new hash generation.
Frequently Asked Questions (FAQs)
Q1: What is SHAKE-128?
SHAKE-128 is a cryptographic hash function and a member of the SHA-3 family. It’s an “eXtendable-Output Function” (XOF), meaning it can produce a hash of any length you specify, unlike most other hash functions.
Q2: How is SHAKE-128 different from SHA-256?
The main difference is the output length. SHA-256 always produces a 256-bit hash, no matter what. SHAKE-128 can produce a hash of any length you choose (e.g., 100 bits, 256 bits, 5000 bits).
Q3: What does the “128” in SHAKE-128 mean?
The “128” refers to the algorithm’s security level. It provides 128 bits of security against all standard cryptographic attacks (like finding collisions or preimages). This is independent of the output length you request.
Q4: Is this tool secure to use with sensitive data?
Yes. This tool is built to run entirely on your computer (client-side). Your input text is processed by your browser and is never sent over the internet to our server. Your data remains completely private.
