TransactionSignature

<init>

Construct a TransactionSignature with partialMerkleTree set to null. This is the recommended constructor when signing over a single transaction.

A wrapper over the signature output accompanied by signer's public key and signature metadata. This is similar to DigitalSignature.WithKey, but targeted to DLT transaction (or block of transactions) signatures.

by

PublicKey of the signer.

partialMerkleTree

required when multi-transaction signing is utilised.

signatureMetadata

attached SignatureMetadata for this signature.

equals

hashCode

isValid

Utility to simplify the act of verifying a signature. In comparison to verify doesn't throw an exception, making it more suitable where a boolean is required, but normally you should use the function which throws, as it avoids the risk of failing to test the result.

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.

isZero

deserialize

Convenience extension method for deserializing a ByteSequence, utilising the defaults.

deserializeWithCompatibleContext

Additionally returns SerializationContext which was used for encoding. It might be helpful to know SerializationContext to use the same encoding in the reply.

hashAs

Compute the algorithm hash for the contents of the OpaqueBytes.

sha256

Compute the SHA-256 hash for the contents of the OpaqueBytes.
