SHAKE128 Hash Generator

SHAKE128 is an extendable-output function (XOF) from the SHA-3 family, based on the Keccak sponge construction. Unlike traditional hash functions that produce fixed-length outputs, SHAKE128 can generate hash values of any desired length, making it incredibly flexible for various cryptographic applications.

SHAKE128 provides 128-bit security strength and can generate outputs from a few bits to thousands of bytes. This variable-length capability makes it ideal for applications requiring custom hash sizes, key derivation, random number generation, and protocols with specific output length requirements.

SHAKE128 offers unique flexibility with its variable-length output, making it perfect for applications requiring specific hash sizes, key derivation functions, deterministic random bit generation, and cryptographic protocols with custom length requirements. It's part of the modern SHA-3 family, providing security independent from SHA-2.

Our SHAKE128 generator operates entirely in your browser with client-side processing, ensuring your data never leaves your device. This provides complete privacy for generating hashes, keys, or random values for security-critical applications.

The tool is valuable for cryptographers implementing custom protocols, developers needing flexible hash lengths, security engineers designing key derivation functions, researchers exploring SHA-3 capabilities, and anyone requiring variable-length cryptographic output with strong security guarantees.

Key Derivation: Generate cryptographic keys of any required length from passwords or seed values.

Random Number Generation: Create deterministic random bit streams for cryptographic applications and simulations.

Custom Protocol Implementation: Generate hashes of specific lengths required by custom security protocols.

Stream Cipher Keys: Produce variable-length keys for stream ciphers and encryption algorithms.

Digital Signatures: Generate signature components requiring specific bit lengths for compliance or optimization.

Using our SHAKE128 generator is straightforward: paste or type your text into the input field, optionally specify your desired output length, and the SHAKE128 hash is generated instantly. The flexible output can be displayed in hexadecimal, base64, or binary format.

SHAKE128 is cryptographically secure and standardized by NIST as part of SHA-3. It's ideal when you need variable-length outputs or when implementing modern cryptographic protocols. For general-purpose hashing with fixed lengths, SHA-256 or SHA-512 may be more widely supported, but SHAKE128 excels in flexibility.
