The first iteration of PRF uses Password as the PRF key and Salt concatenated with i encoded as a big-endian 32-bit integer as the input. (Note that i is a 1-based index.) Subsequent iterations of PRF use Password as the PRF key and the output of the previous PRF computation as the input: F(Password, Salt, c, i) = U 1 ^ U 2 ^ ⋯ ^ U c. where:
