      • hasPublicKey

        public boolean hasPublicKey()
        Return true if a public key is present, false otherwise.
        Returns:
        true if public included, otherwise false.

      • parsePublicKey

        public ASN1Encodable parsePublicKey()
                             throws java.io.IOException
        for when the public key is an encoded object - if the bitstring can't be decoded this routine throws an IOException.
        Returns:
        the public key as an ASN.1 primitive.
        Throws:
        java.io.IOException - - if the bit string doesn't represent a DER encoded object.

      • getPublicKeyData

        public ASN1BitString getPublicKeyData()
        for when the public key is raw bits.
        Returns:
        the public key as the raw bit string...
