title: How to determine SMIME Version for Bouncycastle 155
body: <p>I'm decrypting and removing the signature of signed and encrypted (email) messages. A client asked for the supported SMIME versions and that's where I'm stuck.
  I use bouncycastle 155. Tried to check the release notes but there are statements like:</p>
  
  <p>(Version 147)
  "<strong>RFC 5751</strong> changed the definition of the micalg parameters defined in RFC 3851. The SMIMESignedGenerator is now up to date with the latest micalg parameter set and a constructor has been added to allow the old micalg parameter set to be used."</p>
  
  <p>RFC 5751 describes SMIME Version 3.2. Does bouncycastle fully support SMIME Version 3.2 or just that parameter? What version of SMIME does bouncycastle support?</p>
  
  <p>Thanks for help.</p>
