Which tool can encrypt and compress 32-bit executables and .NET apps without affecting their functionality?

• A. Trojan Proxy
• B. BitCrypter
• C. IExpress Wizard
• D. Virus

Answer: (B)

This question is about packing and encrypting binaries so they can run normally while their contents are hidden from casual inspection. BitCrypter is a tool designed to do exactly that for 32‑bit Windows executables and .NET apps: it encrypts the payload and compresses it, then wraps it with a loader that decrypts and unpacks the code at runtime. Because the actual code is restored in memory as the program starts, the application behaves the same as before, but with added protection against static analysis and simpler distribution. A self-extracting installer tool like IExpress Wizard can compress and package files, but it doesn’t inherently encrypt or protect the executable content, so it doesn’t guarantee the same level of concealment or runtime integrity. Trojan Proxy and a virus refer to types of malware, not to a protective packing/encryption utility, so they don’t fit the described capability.
