#74 Support ECC also on smart cards

[David von Oheimb]

So far, smart card support is available for RSA, but not for Elliptic curves.
Yet meanwhile there are smart cards that (more or less) offer support for ECC.
Would be nice if XCA allowed for using these features of hardware security tokens.

Unfortunately, this requires supporting further PKCS#11 operations like CKM_EC_KEY_PAIR_GEN in lib/pkcs11.cpp . As far as time allows, I might help doing so.

Implement storing EC Keys on a token

I don't have the hardware to test this...

(I tested it later with the OpenDNSSEC SoftHSMv2)
