org.apache.geronimo.util.asn1.x509.SubjectPublicKeyInfo
It turns out that the number of standard ways the fields in a DN should be encoded into their ASN.1 counterparts is rapidly approaching the number of machines on the internet. By default the X509Name class will produce PrintableStrings if the field value will decode to that, next UTF8Strings if the field value will decode to that, and finally BMPStrings if 16 bit characters are required.
The way this is done is with a default encoder which is implemented as follows:
```
 public class X509DefaultEntryConverter extends X509NameEntryConverter { public DERObject getConvertedValue( DERObjectIdentifier oid, String value) { if (str.length() != 0 && str.charAt(0) == '#') { return convertHexEncoded(str, 1); } if (oid.equals(EmailAddress)) { return new DERIA5String(str); } else if (canBePrintable(str)) { return new DERPrintableString(str); } else if (canBeUTF8(str)) { return new DERUTF8String(str); } else { return new DERBMPString(str); } } }
```

    public static byte[] encodeGeneralName(String name) throws IOException {
        return encodeGeneralName(new X509Name(name));
    }


    public static byte[] encodeGeneralName(X509Name x509Name) throws IOException {
        return encodeGeneralName(new GeneralName(x509Name));
