Our SHAKE256 Hash Generator provides instant SHAKE256 hash creation from any text input with real-time processing and customizable output length. SHAKE256 is part of the SHA-3 family standardized by NIST and offers unique flexibility as an extendable-output function (XOF) with high security strength. Simply type or paste your text, adjust the desired output length, and watch as the SHAKE256 hash is generated immediately.

What makes this tool special is its combination of real-time processing, variable output length, and high security strength. You can adjust the output length from 8 to 8192 bits to match your specific needs, and the hash updates instantly as you type or change the length. The tool also displays character and byte counts for your input, helping you understand exactly what's being hashed. The generated hash is presented in a clean, easy-to-read format with convenient copy functionality.

SHAKE256 provides a security strength of 256 bits against all attacks, regardless of the output length. This makes it particularly useful for high-security applications that need variable-length output while maintaining maximum security strength. Unlike fixed-length hash functions like SHA3-512 or Keccak-512, SHAKE256 can produce outputs of any desired length, offering unique flexibility for specialized cryptographic applications.

Your privacy is completely protected as all hash generation happens locally in your browser. No data is ever sent to external servers or stored anywhere, ensuring your sensitive information remains private. The tool works entirely offline once loaded, making it safe for confidential data processing and perfect for environments with restricted internet access.
