libghc-crypto-api-dev binary package in Ubuntu Bionic arm64

 A generic interface for cryptographic operations, platform independent
 quality RNG, property tests and known-answer tests (KATs) for common
 algorithms, and a basic benchmark infrastructure. Maintainers of hash
 and cipher implementations are encouraged to add instances for the
 classes defined in Crypto.Classes. Crypto users are similarly
 encouraged to use the interfaces defined in the Classes module. Any
 concepts or functions of general use to more than one cryptographic
 algorithm (ex: padding) is within scope of this package.
 .
 This package provides a library for the Haskell programming language.
 See http://www.haskell.org/ for more information on Haskell.
