Function split

split(
    ciphersuite: Ed25519Sha512Impl,
    secret: keys.SigningKey,
    maxSigners: number,
    minSigners: number,
    identifiers: keys.IdentifierList,
    rng: RandomSource,
): Promise<[Map<string, keys.SecretShare>, keys.PublicKeyPackage]>
Splits an existing key into FROST shares.

This is identical to generateWithDealer but receives an existing key instead of generating a fresh one. This is useful in scenarios where the key needs to be generated externally or must be derived from e.g. a seed phrase.
Parameters
- ciphersuite: Ed25519Sha512Impl
  The Ed25519Sha512 ciphersuite instance
- secret: keys.SigningKey
  The secret signing key to split
- maxSigners: number
  Maximum number of signers
- minSigners: number
  Minimum number of signers (threshold)
- identifiers: keys.IdentifierList
  Identifier list configuration
- rng: RandomSource
  Random number generator
Returns Promise<[Map<string, keys.SecretShare>, keys.PublicKeyPackage]>
A Promise of a tuple of [Map of SecretShares by identifier string, PublicKeyPackage]

Throws
If parameters are invalid
