title: Private key: Convert a valid EC key to a equivalent RSA key
body: <p>I have a valid private key. When I <code>cat</code> it, I see (masked for security).</p>
  <pre><code>-----BEGIN PRIVATE KEY-----
  MIGHAgEAMBMGByqGS[xxx]6a7EXt7CT6wSgDc+
  zYYSBiL6cm[xxx]aikHV47TBj4PdBW1c
  wzmUrOf2s6PWS0[xxx]LPdTjOD
  -----END PRIVATE KEY-----
  </code></pre>
  <p>And I am quite sure it is valid since <code>openssl ec -in my-private.key -text</code> I see the key fine.</p>
  <p>I was wondering, is there a way to convert a EC key into RSA please? And if yes, how to do such?</p>
  <p>Thank you</p>
