| 3 | pySim-trace is a utility for high-level decode of APDU protocol traces such as those obtained with Osmocom SIMtrace2 or osmo-qcdiag. |
||
| 4 | |||
| 5 | pySim-trace leverages the existing knowledge of pySim-shell on anything related to SIM cards, including the structure/encoding of the various files on SIM/USIM/ISIM/HPSIM cards, and applies this to decoding protocol traces. This means that it shows not only the name of the command (like READ BINARY), but actually understands what the currently selected file is, and how to decode the contents of that file. |
||
| 6 | |||
| 7 | pySim-trace also understands the parameters passed to commands and how to decode them, for example of the AUTHENTICATE command within the USIM/ISIM/HPSIM application. |
