Example 2 with KerberosString

use of sun.security.krb5.internal.util.KerberosString in project jdk8u_jdk by JetBrains.

the class PrincipalName method asn1Encode.

     * names are encoded. To encode the realm, call getRealm().asn1Encode().
     * @return the byte array of the encoded PrncipalName object.
