This project is stage 1 of establishing communication with a temperature measurement device that uses encrypted communication.
The encryption methods and key are no longer available but the PC program EXE that does communicate with the device is available for analysis. Source code is unavailable.
It is known that the application uses MicroSoft Windows API [url removed, login to view] and bcrypt.dll.
Stage 1 will involve finding a person with necessary skills using a disassembly tool such as IDA or REC, and disassemble the program EXE that is available.
Stage 2 will involve identifying encryption methods and key from the disassembly and successfully encrypting the device communications scripts.
Stage 1 budget is small, stage 2 budget will be more significant.

Hello, I have a lot of experience with reverse engineering. Please send me the target exe first. I want to check how much effort and time it would take me. Best regards, Drago
