Re^7: Crypt::RSA Cant load private key

DER is a purely binary format. If you base64 encode DER data, and add those -----BEGIN/END----- blocks you get something called PEM. It's pretty easy to convert between them:

my $der = MIME::Base64::decode_base64(
  join "\n" =>
    grep { !/^-----(BEGIN|END)\s.*-----$/ }
      split /\n/, $pem
  );

I leave the conversion in the opposite direction as an exercise for the reader.
