title: AES key and iv from RSA private key
body: <p>Is there a relationship between the content of a private RSA key (private exponent, modulus and primes) and a AES-128-cbs key and iv?</p>
  
  <p>I know that you can encrypt your private key using AES in which case
  the AES-iv is supplied in the pem file and the AES-key is 
  calculated using MD5 over secret-password and the first 8 bytes 
  of the AES-iv. </p>
  
  <p>However I have AES encrypted data and a private RSA key that I can read.
  Is there a standard on how to derive the AES-key and AES-iv from the 
  RSA key content,  maybe from the prime numbers inside. Is 
  there some standard that is normally used?</p>
