seamlessly connected to the project. Another is the analysis of the OBJ format, which is much simpler than the C ++ source code. There is a symbol in my OBJ file. This OBJ will tell me that there is a symbol here. So I think the disassembly OBJ is safer than the disassembly EXE. The specific method is to parse the OBJ file, keep the data part unchanged, decompile the code part, convert it into hard-to-understand code, and then output an ASM, call the ASM compiler to generate a new OBJ file and

obtains the public key, it encrypts the confidential information and sends it to Party A. Party A decrypts the encrypted information with another private key. Party A can only use its private key to decrypt any Information encrypted by its public key. Asymmetric encryption algorithms have good confidentiality and eliminate the need for end users to exchange keys. However, encryption and decryption take a

IntroductionEncryption refers to the process of blurring data by using a key or a password. In SQL Server, encryption does not replace other security settings, such as preventing unauthorized people from accessing the database or the Windows system where the database instance resides, or even the computer room where the database resides, but as the last line of defense when the database is cracked or the ba
