@Drux I meant the entropy of H(K). I want to increase.

comment How to use HKDF to combine two keys
Thank you for explanation. One more question.Will using a hash function be better than use XOR the two keys(Considering the entropy)?

comment How to use HKDF to combine two keys
In CSE I have seen HKDF is recommended to use for key concatenation because it preserves the entropy unlike in a XOR function. crypto.stackexchange.com/questions/11405/…;. So why you are saying HKDF is pointless. Please enlighten me. I want the finale key to be as random as possible. Thats why I am using HKDF to concatenation without using HASH alto or a XOR function.
