Total Shards (n) Data Shards (k)

Params info...

n >= 5

2 <= k < n

(n - k) must be even

Data k Parity m Threshold t

Configuration Tips

More availability = reduce k or t;
More confidentiality = increase m.
If someone controls t shards they can decrypt; with fewer than t shards they cannot.
m — in the context of RS is the number of redundant parity shards.
t — in the context of SSS, this is the threshold: the minimum number of Shamir shards required to recover the secret.
