What is libgfshare2
libgfshare2 is:
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.
For instance, you might split a GPG key using a 3-of-5 share and put one
share on each of three computers, and two shares on a USB memory stick; then
you can use the GPG key on any of those three computers using the memory
stick, but if the memory stick is lost, you can recover the key by
bringing the three computers together.
