Command line tool that decrypts an OPVault keychain and dumps it to stdout.

To compile: gcc -o opvault opvault.c cJSON.c -lcrypto

Usage: ./opvault </path/to/mykeychain.opvault> <password>

This is just a proof of concept; I'll be recycling this into proper OPVault
support in 1pass later and deleting this tool.

This uses OpenSSL's libcrypto for the math instead of all the homegrown
crypto this project is otherwise using. I'll probably migrate the rest in
this direction, too, since this wasn't as bad as I expected to use and
gets you all the package-manager mojo of automatic bug fixes and security
patches and shared code, etc.

cJSON parses JSON in C. That is from

An example OPVault keychain from AgileBits is available here:
#ifndef _INCL_KEYHOOK_H_
#define _INCL_KEYHOOK_H_

int pumpKeyHook(void);
void deinitKeyHook(void);
int initKeyHook(void);


// end of keyhook.h ...
