# For those quick little scripts one writes in one's bin
# that annoyingly keep falling out of maintainance... right?

SSSS.split("Top Secret!", threshold: 2, shares: 3)
#~> ^\["1-\h+", "2-\h+", "3-\h+"\]$
# Note that the split has random outputs on the same inputs.

SSSS.combine("3-055562917c41e68c6ab2c8", "1-27bf3cbfe8d2c25c7e8928")
#=> Top Secret!
# Pregenerated splits combine to reproduce the secret.
