sign
suspend fun sign(roomUuid: RoomUUID, secretShare: EcdsaSecretShare, msgHash: MessageHash, derivationPath: IntArray): EcdsaSignature
Signs a message using ECDSA and multi-party computation.
This function requires threshold number of parties to participate in the signing. Unlike Schnorr-based signatures, ECDSA requires the message to be hashed before signing. You should use a secure hash function like SHA-256 to create the msgHash parameter.
Return
The signature of the message, which can be verified using the public key
Parameters
room
The UUID of the signing room
secret
The secret share to be used for signing
msg
The hash of the message to be signed as a MessageHash object
derivation
The BIP-32 non-hardened derivation path to use for signing
