The key and IV is derived by concatenating D_1, D_2, etc until
enough data is available for the key and IV. D_i is defined as:
- D_i = HASH^count(D_(i-1) || data || salt)
+ D_i = HASH^count(D_(i-1) || data || salt)
where || denotes concatenation, D_0 is empty, HASH is the digest
algorithm in use, HASH^1(data) is simply HASH(data), HASH^2(data)
