commit 8f3330542174b97570ac9ddd6daf225331d1e016
Author: Jakuje <jakuje at gmail.com>
Date:   Wed Apr 5 09:44:34 2017 +0200

    Make CardOS 5.3 working with OpenSC (#1003)
    
    * Set security context for CardOS 5.3 with p1=0x41 (as Coolkey does)
    
    * Do not emulate signatures in CardOS 5.3
    
    Remove the bogus SC_ALGORITHM_NEED_USAGE which prevents using the
    actual implementation in cardos_compute_signature().
    
    It might be bogus also in previous version, but I don't have a way
    to verify against these cards.
    
    * Do not advertise RSA-X-509 mechanism for CardOS 5.3 (card strips padding)
