SequenceHash: multihashing for the rest of us

Multihashing is one of those cryptographic tasks that’s easy not to think about too much. This is unfortunate, because multihashing is a common stumbling point when cryptographers try to use hashes. As part of our goal to “fix software, not bugs,” Trail of Bits is introducing SequenceHash and its sister function SequenceMAC, a pair of related hash constructions that bring secure multihashing to developers using hash functions other than Keccak. We hope SequenceHash and SequenceMAC will help cryp...
