Binary package “libghc-entropy-dev” in ubuntu lunar

cryptographically-strong entropy

 It is a platform-independent method to obtain cryptographically strong
 entropy (urandom on Linux, CryptAPI on Windows, patches welcome). Users
 looking for cryptographically strong (number-theoretically sound) PRNGs
 should see the DRBG package too.

 This package provides a library for the Haskell programming language.
