-   This routine promises not to make any copies of the password or salt that aren't
-   eradicated before completion.
-   
-   The size of the result buffer is used to produce the derivedKey.
-   
-   Be careful when using CFTypes for secrets, they tend to copy data more than you'd like.
-   If your password and or salt aren't already in CF types use the buffer versions above.
-   
-   If you already have the data in this form, the interface will unwrap and not copy the data anywhere extra for you.
