Asn1OctetString
Interface describing an ASN.1 OCTET STRING.
Signum will attempt to parse any ASN.1 OCTET STRING's content as ASN.1. If this attempt succeeds, this will be an Asn1EncapsulatingOctetString. Otherwise, it will be an Asn1PrimitiveOctetString.
If you are expecting arbitrary bytes, Asn1OctetString is the correct type to look for. (Your arbitrary bytes might inadvertently be valid ASN.1!)
