About Shake-256

SHAKE-256 is a extendable-output function (XOF) from the SHA-3 family, standardized by NIST in 2015. It provides a higher security level than SHAKE-128 and can generate an arbitrary number of output bits, making it suitable for applications requiring variable-length digests with strong security guarantees.

Based on the Keccak sponge construction, SHAKE-256 offers security comparable to 256-bit symmetric keys. It is particularly well-suited for applications such as key derivation, random number generation, and generating large cryptographic keys where a higher security level is required.

Note:SHAKE-256 is more secure than SHAKE-128 and is recommended for applications requiring a higher level of security. The output length should be chosen based on the specific security requirements of your application.

Common Use Cases

  • High-security key derivation functions
  • Cryptographic random number generation
  • Generating large cryptographic keys
  • Applications requiring variable-length digests
  • Post-quantum cryptography applications
