I tested the reserved COMP128v23 code from www.hackingprojects.net the values in the python file match the ones outputed by the sysmoSIM-GR1 (which also supports COMP128 v2 and v3) so I implemented it in C, and added it to libosmocore I then checked the output from osmo-auc-gen again the values provided also the python code and all values matched
Here are te patched WARNING: I also renamed COMP128 to COMP128v1, but don't know if this breaks any compatibility with other projects
