haskell-raaz-utils 0.1.1-2build1 (amd64 binary) in ubuntu bionic

 Raaz uses strong typing to eliminate some common errors that occur in
 cryptographic settings, such as side channel attacks.
 .
 This package implements basic types and cryptographic primitives like
 hashes, macs etc. Actual network protocols are expected to use this
 library. Common abstractions, such as packet parsing, are part of
 this library.
