Lurker Posted August 20, 2017 Report Share Posted August 20, 2017 is it truly encrypted? or just proprietary format file? have you ever study the files before? Quote Link to comment Share on other sites More sharing options...
killercode Posted August 21, 2017 Author Report Share Posted August 21, 2017 I think yes, based on Nissan Connect LCN2 manual map data on HERE SD-Card are encrypted by Bosch company, therefore user can't change data on SD-Card, but I'm still working on it, I'm looking for a way how can I copy OpenstreetMap on HERE SD-Card, moreover I believe for solve this problem I'll know what encryption method used by Bosch for encryption, as well as I did many research and then I think they used Advance Data Encryption tools and may be they used AES-256 encryption method(this is a my guess), anyway I'll know who has same experience, about this issue Quote Link to comment Share on other sites More sharing options...
