The GUIdumpASN application allows you to view and print a human readable version of an Abstract Syntax Notation One (ASN.1) file. ASN.1 is a standard and flexible notation that describes data structures for representing, encoding, transmitting, and decoding data.

Application output can be saved as a text file, and options may be configured to adjust output. The application supports drag-and-drop, so you can run the application and drop a file on it to display the ASN.1. You can also associate file extensions with the application to allow immediate launch when a certain file type is double-clicked.
