for security reason , 128 bytes for the private key
it's still working till 2010, after it will be
attacked
and so factorise the modulus, then attack RSA, after 
256 bytes will be safe .

extra bytes, in my opinion those bytes are just a
padding to make so difficult to find the key .

 try this 

openssl rsa -in file.pem -text
may be this help you to know all the component of the
Rsa keys .

if not , try as the doctor mr Ludovic Rousseau said.
