I copied and pasted this proto from the source.
It's wrong. Correct one is
string hash_hkdf(string algo, string ikm [, int length = 0 [, string info =
'' [, string salt = '']]])
so my proposal is
string hash_hkdf(string algo, string ikm, string salt [, string info = ''
[, int length = 0]])
- Set salt to NULL if salt cannot be used, reject null string as invalid.
I will change my mind if there is convincing logical
reason(s) not to do this. I suppose there isn't.
