libgfshare-dev 2.0.0-4 (ppc64el binary) in ubuntu bionic

 This library implements Shamir's method for secret sharing, which can be
 used to split a secret (like a GPG secret key) into multiple parts, so that
 at least some number of those parts are needed to recover the original file,
 but any smaller combination of parts is useless to an attacker.
 .
 This package contains header files and static libraries, needed to compile
 programs that use libgfshare.
