// There is  no size limitation because the file is consumed
// in streaming mode internally.

// Hash using HAVAL
// There are two additional properties relevant to HAVAL:
// HavalRounds, and KeyLength.
// HavalRounds can have values of 3, 4, or 5.
// KeyLength can have values of 128, 160, 192, 224, or 256
