Generate shares from private key

[typestring]

Is it possible to split an existing private key into tss shares?

Ah so if someone have a private key, he could act like a central dealer to split the key into shares. The process is not direct available in tss-lib, but it's quite like the set u_i into your given key value, and other parties has 0, the remaining process is the same(create shamir shares based on u_i, generate preparameters, etc)
