Not yet needed.  I could implement gcry_pubkey_testkey to allow for RSA
and DSA  public key fixup.  Shall I?

The key representation in the API are not a problem performance wise.
There are lot of options to speed up public key computations.  gniibe
recently applied a patch which not only restored RSA performance but
actually improved it a lot.  Recall that there has been no performance
work for 10 years or so.



Die Gedanken sind frei.  Ausnahmen regelt ein Bundesgesetz.
