I dunno, what does http://www.google.com/search?q=cryptopp say? That was a rhetorical question.

I think linhan major obstacle in posting a more elaborate and understandable question is his/her lack of command of english language. Looking back at previous postings, linhan uses a laconic, almost telegraphic style, but I have the impression that the questions are not trivial at all.
I can attest this out of my own previous experience, when years ago, stemming from the fact that I did not speak in a very sophisticated English style,
people assumed I was irretrievably stupid. . .
If linhan could make an effort and elaborate a little on the contents of the posting, something interesting may come out of the post and the discussion.

?Win95IsDebuggerPresent@@YGHXZ
int __stdcall Win95IsDebuggerPresent(void) a windows api (not sure whats that old 95 is doing in there never reversed on that os

read about symbol decoration and name demangling in c++ these names are decorated names since you say ida i think ida has a switch somewhere to turn on name demangling

if ollydbg its in ctrl+o -->addresss -> demangle symbolic names --> check mark

its crypto++ some crypto
