We need to reverse engineer a symmetric encryption key, to restore fields of a database.
The encryption was performed by a Visual Basic 6 (VB6) program, probably using AES. The encryption key is contained in the program itself. The key may be static, or generated at runtime, dynamically. In the latter case, we need the algorithm to generate the key.
It may be necessary to decompile the binary VB6 files. The VB6 application consists of one exe file and one dll file together having a size of approximately 10mb.
We provide example databases with chiffre, plaintext versions of the same database, and the binaries of the VB6 program.
