Unsorted entries in PLIST files have generated a pkglint warning for at
least 12 years. Somewhat more recently, pkglint has learned to sort
PLIST files automatically. Since pkglint 5.4.23, the sorting is only
done in obvious, simple cases. These have been applied by running:
pkglint -Cnone,PLIST -Wnone,plist-sort -r -F
Shamir's Secret Sharing Scheme (SSSS) is an implementation of a
threshold scheme for sharing a secret between third parties, and
requiring a threshold of those parties to collaborate to reveal the
secret.
Taken from the Wikipedia article about Secret Sharing:
In cryptography, a secret sharing scheme is a method for
distributing a secret amongst a group of participants, each of
which is allocated a share of the secret. The secret can only
be reconstructed when the shares are combined together;
individual shares are of no use on their own.
Shamir's scheme is provable secure: in a (t,n) scheme one can prove
that it makes no difference whether an attacker has t-1 valid shares
at his disposal or none at all; as long as he has less than t shares,
there is no better option than guessing to find out the secret.
