Secret Share is software that performs Shamir's secret sharing method.

The share and combine methods support the following four methods:

After sharing, each share piece is about 80 bytes larger than the source data.

No error correction code is used.

The calculation is done using the Galois field.

The generated share piece is like a series of coefficients of Galois field of simultaneous equations.

There is no limit on the size of files (data) that can be handled.

However, I think that "about 1 MB" will be the realistic maximum size.

The reason is the time it takes to “combine“.

The combine of secret sharing using "Shamir's secret sharing scheme" takes a lot of time.

If you combine 150 MB share pieces in 3 combine, the required time will be about 1 hour to 3 hours.

Up to "about 1 MB" can be processed within one minute.
