Is it necessary to add a new method to generate digest in transaction information? as follows

[wdd906]

    String digest = Base58.encode(hashTypedData("TransactionData", txBytes));

public byte[] hashTypedData(String typeTag, byte[] data) {
byte[] typeTagBytes = String.format("%s::", typeTag).getBytes();
byte[] dataWithTag = new byte[typeTagBytes.length + data.length];
System.arraycopy(typeTagBytes, 0, dataWithTag, 0, typeTagBytes.length);
System.arraycopy(data, 0, dataWithTag, typeTagBytes.length, data.length);
Blake2b.Blake2b256 blake2b256 = new Blake2b.Blake2b256();
return blake2b256.digest(dataWithTag);
}

@wdd906 Sorry for late, it can be added. Can you describe what is your use case here?

@GrapeBaBa To get the transaction hash for offline sign.
