[ssh_x509] scp PKCS#11?

[ssh_x509 at roumenpetrov.info]

Roumen,

I've just noticed that scp doesn't support PKCS#11?

$ /opt/pkxissh/bin/scp -I /usr/lib64/opensc-pkcs11.so README.x509v3
jose at server.local:
/opt/pkxissh/bin/scp: illegal option -- I
usage: scp [-12346BCpqrv] [-c cipher] [-F ssh_config] [-i identity_file]
           [-l limit] [-o ssh_option] [-P port] [-S program]
           [[user@]host1:]file1 ... [[user@]host2:]file2
$

Can you suggest an another way to secure copy using PKCS#11?

Thanks!

Jose
