I believe openssl crypto module (http://www.openssl.org/docs/crypto/crypto.html) implements all you need. It is written in C, not CPP, but I believe you can easily warp it in a class, if you need some OOP feature.

 

Also, are you set in stone for this method?

 

The method I am using is (register):

 

1) Generate a random number.

2) Decrypt the password received by the client

3) Calculate a hash using the password and the random number

4) Save on the DB the random number (step 1) and the hash (step 3).

 

To authenticate:

1) Decrypt the password received by the client

2) Calculate the hash using the random number saved on database.

3) Check if saved hash match with the one I just calculated.
