). WebI'm aware that it's advisable to rotate cryptographic keys periodically. HKDF accepts high-entropy input (IKM - Input Key Material), and expands it to an arbitrary length. It also accepts a salt, the RFC states that "the use of salt adds significantly to the strength of HKDF". Naturally, changing the salt results in distinct Output Key Material ... WebJul 22, 2024 · The extract step is simply HMAC-Hash (salt, IKM) The output length of your hash will determine the maximum entropy produced by HKDF-Extract. The octet length of your IKM is not the same as the entropy of the IKM. For example, a 256-bit EC Diffie-Hellman shared secret would only have around 128 bits of entropy. hobe sound building permits
