TransactionSignature

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

PublicKey of the signer.

The bytes are always cloned so that this object becomes immutable. This has been done to prevent tampering with entities such as net.corda.core.crypto.SecureHash and net.corda.core.contracts.PrivacySalt, as well as preserve the integrity of our hash constants net.corda.core.crypto.SecureHash.zeroHash and net.corda.core.crypto.SecureHash.allOnesHash.

The start position of the sequence within the byte array.

required when multi-transaction signing is utilised.

attached SignatureMetadata for this signature.

The number of bytes this sequence represents.

Compare byte arrays byte by byte. Arrays that are shorter are deemed less than longer arrays if all the bytes of the shorter array equal those in the same position of the longer array.

Copy this sequence, complete with new backing array. This can be helpful to break references to potentially large backing arrays from small sub-sequences.

Same as copy but returns just the new byte array.

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

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

Compute the algorithm hash for the contents of the OpaqueBytes.

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.

Returns a ByteArrayInputStream of the bytes.

Write this sequence to a ByteBuffer.

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

A new read-only ByteBuffer view of this sequence or part of it. If start or end are negative then IllegalArgumentException is thrown, otherwise they are clamped if necessary. This method cannot be used to get bytes before offset or after offset+size, and never makes a new array.

Create a sub-sequence of this sequence. A copy of the underlying array may be made, if a subclass overrides bytes to do so, as OpaqueBytes does.

Take the first n bytes of this sequence as a sub-sequence. See subSequence for further semantics.

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.

Write this sequence to an OutputStream.
