Variable: KDF_SHAKE256

const KDF_SHAKE256: KDFFactory

SHAKE256 key derivation function.

A one-stage KDF using the SHAKE256 extendable-output function (XOF) with an output length (Nh) of 64 bytes.

Depends on the following Web Cryptography algorithms being supported in the runtime:

  • SHAKE256 (cSHAKE256 without any parameters) digest

This is a factory function that must be passed to the CipherSuite constructor.

Tip

An implementation of this algorithm not reliant on Web Cryptography is also exported by @panva/hpke-noble
