verify
Function to verify a SignableData object's signature. Note that SignableData contains the id of the transaction and extra metadata, such as DLT's platform version. A non-null partialMerkleTree implies multi-transaction signing and the signature is over the root of this tree.
Parameters
transaction's id (Merkle root), which along with signatureMetadata will be used to construct the SignableData object to be signed.
Throws
if the key is invalid.
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.
if the signature scheme is not supported for this private key or if any of the clear or signature data is empty.
