func DecryptSplit ¶

func DecryptSplit(encryptedShare []byte, privKeyECDSA *ecdsa.PrivateKey) (*KeySplit, error)

DecryptSplit decrypts an encrypted key split and verifies its integrity.

func (*KeySplit) VerifySignature ¶

func (ks *KeySplit) VerifySignature() error

VerifySignature checks that the key split signature matches the owner key.

type KeySplitData ¶

type KeySplitData struct {
	Shares []ShamirShare
	PartialWalletBackupID
