Hello, I'm using CryptoPP library and I have problem with exporting public key as 128byte lengths array of byte. (1024 bit)

I'm do it this way :
Code:
ByteQueue queue;
publicKey.Save(queue);
queue.CopyTo( StringSink(encodedPublicKey) );
But It save as 160 byte length text, I guess its encrypted key. How to get decoded key (128B length) ? And later how to import decoded key?
