// the message input to the compression function of H is v bits). The

// HASH FUNCTION VALUE u VALUE v
// MD2, MD5 128 512

// SHA-224 224 512

// SHA-512/256 256 1024
// Furthermore, let r be the iteration count.
// We assume here that u and v are both multiples of 8, as are the
// lengths of the password and salt strings (which we denote by p and s,
// respectively) and the number n of pseudorandom bits required. In
// addition, u and v are of course non-zero.

// a particular "purpose" that is identified by a byte called "ID".
// This standard specifies 3 different values for the ID byte:
// 1. If ID=1, then the pseudorandom bits being produced are to be used
// as key material for performing encryption or decryption.
// 2. If ID=2, then the pseudorandom bits being produced are to be used
// as an IV (Initial Value) for encryption or decryption.
// 3. If ID=3, then the pseudorandom bits being produced are to be used
// as an integrity key for MACing.
// 1. Construct a string, D (the "diversifier"), by concatenating v/8
// copies of ID.

// truncated to create S). Note that if the salt is the empty
// string, then so is S.
S := fillWithRepeats(salt, v)
// 3. Concatenate copies of the password together to create a string P
