NSA having something to do with an extra set of keys inside the Windows advapi.dll file. According to the article the extra keys are in this dll on every version of Windows between Windows 95 OSR2 and Windows 2000.   > I happened to come by an old article (dated 04.09.1999) about NSA > having something to do with an extra set of keys inside the Windows > advapi.dll file.

No, they are from Microsoft, and they're supposed to provide a signature for a plugin interface that allows NSA to exchange it with its own implementation in a safe way. At least that's the official technical explanation. > Three questions that came to mind: > 1. has anything similar been reported about Windows XP? No. The architecture change removed the need for such a special implementation. > 2. what kind of software would one use to check the dll for keys? A disassembler with good structure analysis. > 3. if answer to 2 is "hex editor" or other low level editor: how would > you know that you have found a key? If there's some DER or BER encoded structure that looks like an exponent plus a big composite integer of a typical site. Comentarios (0) Mostrar/Ocultar comenarios
