sss = Rcrypto::SSS.new

s = "nghiatcxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
puts s
puts s.length
# creates a set of shares
arr = sss.create(3, 6, s, true)
# puts arr

# combines shares into secret
s1 = sss.combine(arr[0...3], true)
puts s1
puts s1.length

s2 = sss.combine(arr[3...6], true)
puts s2
puts s2.length

s3 = sss.combine(arr[1...5], true)
puts s3
puts s3.length
```

**Use encode/decode Hex**  
```ruby
