Do you need the function like Serializable interface?
You can use the getXXX() method to convert PublicKey to byte[];
And use the setXXX() method to convert byte[] to PublicKey;
Here's the getXXX/setXXX method PublicKey support:
1 DSAPublicKey: getY/setY;
2 ECPublicKey: getW/setW;
3 RSAPublicKey: getExponent/setExponent and getModulus/setModulus;
