keytool may generate duplicate extensions

XMLWordPrintable

        keytool -ext allows extension types to be provided either with a name or with an object identifier. If the same type is provided twice with name and OID respectively, it generates a certificate with duplicate extension types. Such a certificate will not be accepted by Java.

        Error message seen: keytool error: java.security.cert.CertificateParsingException: java.io.IOException: Duplicate extensions not allowed
