crypto: add virtual dtor to KeyPairGenerationConfig
Browse files Browse the repository at this point in the history
Currently the KeyPairGenerationConfigs class has a virtual function
but no virtual destructor which means that if delete is called on a
KeyPairGenerationConfig pointer to a derived instance, the derived
destructor will not get called.

The following warning is currently being printed when
compiling:

warning: delete called on 'node::crypto::KeyPairGenerationConfig' that
is abstract but has non-virtual destructor [-Wdelete-non-virtual-dtor]
    delete __ptr;

This commit adds a virtual destructor.
