title: OpenSSL generate and sign certificate with custom subject fields
body: <p>I need to create and sign (I am CA) certificate with custom subject (, SERIALNUMBER=...,).</p>
  
  <p>So far I have modified openssl config file so I am able to inclde custom fields in subject.</p>
  
  <pre><code>[ new_oids ]
  SERIALNUMBER = 1.2.3.4.1333
  </code></pre>
  
  <p>Problem is, that after signing such certificate new fields appear in that strange number format - </p>
  
  <pre><code>C = FI
  O = Maahanmuuttovirasto
  1.2.3.4.1333 = 00REINIS00
  </code></pre>
  
  <p>where and what should I change in my openssl config file to generate certificate with normal field names? How do I tell to signing process that 1.2.3.4.1333 should be encoded as 'SERIALNUMBER'.</p>
  
  <p>Thank you,
  Beef</p>
