Open Type Decoding

An ASN.1-encoded message may contain fields that contain "open type" data. These are fields whose type is typically determined by the value of another field at run-time. ASN1VE will try to find the ASN.1 type definition from the assigned ASN.1 file for each open type field. If successful, ASN1VE will decode the open type field using the appropriate ASN.1 type definition.

If ASN1VE is not able to determine the ASN.1 type, then it will give options to the user to select the type definition. The failed to decode open type node will be displayed with a warning icon. The user can right click on this node and select the Decode As option. This will display the ASN.1 type selection box for this open type data. On selection of ASN.1 type definition, ASN1VE will decode this open type data with the selected type definition.

Note: The right click menu option, "Decode As" will be available for failed to decode open type node only.
Refer to the configuration option to disable this automatic open type decoding operation.
