I don't know specifically what your question is, but i think you're
asking about the communications channel when GnuPG prompts for a

On modern GnuPG systems, the communications channel is:

 * gpg needs access to secret key material.

 * it asks gpg-agent for the use of a secret key (possibly launching
   gpg-agent if it's not already launched).

 * gpg-agent checks to see whether it has unlocked access to that secret
   key.  if it does, it can grant access directly.

 * if it does not, it launches some version of pinentry to get a
   passphrase from the user.  different versions of pinentry have
   different ways of communicating with the user.

GnuPG itself should never see the password, unless it is invoked with
special commands that route the password handling back to
it. (e.g. --pinentry-mode=loopback).

Can you explain more about what you mean by "hack the password"?
