Figure 6 shows our testing of the download command within RGDoor, specifically a command “download$c:\windows\temp\test.txt” that downloads the file uploaded in our previous test. We chose to use the key “89” (0x89) in this test to showcase RGDoor’s ability to use any hexadecimal byte as a key, which resulted in an encoded command string of “7eb+5+Xm6O2t6rPV/uDn7eb++tX97OT51f3s+v2n/fH9”. RGDoor responds to this command with the encoded string “/ez6/eDn7ri7uoM=”, which when decrypted with the “89” key results in the string ‘testing123\n’, which is the contents of the “test.txt” file.
