Status C++ API for Pretty Curved Privacy

While I'm waiting for Frank to fix the AIX libsodium issue I thought it would be a good idea to start with a C++ API for Pretty Curved Privacy. And I've to admit, that it is really fun to do that. Working with the C++ API makes the whole thing a LOT easier. Here's an example of how to generate some keys and encrypt some data:

#include <pcp++.h>
#include <string>
#include <iostream>
using namespace pcp;
using namespace std;
int main() {
try {
/* generate 2 secret keys */
Key A = Key("a", "alicia", "alicia@local");
Key B = Key("b", "bobby",  "bobby@local");
/* extract the public parts of them */
PubKey PA = A.get_public();
PubKey PB = B.get_public();
/* decrypt the secret keys */
A.decrypt("a");
B.decrypt("b");
/* create crypto objects (1st for the sender, 2nd for the recipient) */
Crypto A2B(A, PB);
Crypto B2A(B, PA);
/* actually encrypt something (alicia to bobby) */
string cipher = A2B.encrypt("Hallo");
/* and decrypt it (bobby from alicia) */
ResultSet res = B2A.decrypt(cipher);
/* see if it worked as expected */
if(res.String == "Hallo")
cout << "ok" << endl;
else
throw pcp::exception("wtf - decryption failed (uncatched as well)");
}
catch (pcp::exception &E) {
cerr << "Catched exception: " << E.what() << endl;
}
return 0;
}

Now, that's easy, isn't it? At least I like it. The API is not ready though, signing and derived keys are not done yet. More example code can be seen in the C++ unittest.
