[Libvncserver-common] vncclient to Apple ARD

[Luc R. <ren...@gm...>]

Hi,

I have written a client using libvncclient. Since OSX Lion, I have to use the rfbARD authentication method, which internally uses libgcrypt. It works fine, except that it takes a very long time (several minutes) to pass the authentication.

It seems stuck in the call to 'gcry_mpi_randomize'. I read somewhere that the first call to that function might take a long time (the following ones would be fast).
I commented out the line (line 2403 rfbproto.c), and it still works fine.  (I'm running the client on Linux 64bit, Opensuse 12.1).

Anyone with security knowledge knows about this ?

thanks,

Luc
