fun PublicKey.verify(signatureData: ByteArray, clearData: ByteArray): Boolean

Helper function to verify a signature.

Parameters

signatureData - the signature on a message.

clearData - the clear data/message that was signed (usually the Merkle root).

Exceptions

InvalidKeyException - if the key is invalid.

SignatureException - if this signatureData object is not initialized properly, the passed-in signatureData is improperly encoded or of the wrong type, if this signatureData algorithm is unable to process the input data provided, etc.

IllegalArgumentException - if the signature scheme is not supported for this private key or if any of the clear or signature data is empty.

fun PublicKey.verify(transactionSignature: TransactionSignature): Boolean

Helper function to verify a metadata attached signature. It is noted that the transactionSignature contains signatureData and a MetaData object that contains the signer's public key and the transaction's Merkle root.

Parameters

transactionSignature - a TransactionSignature object that .

Exceptions

InvalidKeyException - if the key is invalid.

SignatureException - if this signatureData object is not initialized properly, the passed-in signatureData is improperly encoded or of the wrong type, if this signatureData algorithm is unable to process the input data provided, etc.

IllegalArgumentException - if the signature scheme is not supported for this private key or if any of the clear or signature data is empty.
