    20 We'll combine two hash functions using an appropriate combiner depending on the hash function properties that are required, see [http://tahoe-lafs.org/pipermail/tahoe-dev/2010-June/004575.html Zooko's notes] about hash function combiners. The Comb4P hash function combiner preserves most (but not all) security properties of the hashes is safest combiner in case we actually rely on a hash function property, though because the extra work comes in the form of a set of final Feistel rounds, this may negatively effect performance when combined with the tree hashing mode Tahoe-LAFS uses.
