While on Leap 42.3, I was experimenting with an Aladdin / SafeNet eToken PRO, which is a certificate-based PKI USB authentication token.
I found this tutorial that recommended, among others, installing the opensc package:
Configuring Smart Card authentication on SUSE Linux Enterprise https://www.suse.com/c/configuring-smart-card-authentication-suse-linux-ente...
These days I realized that opensc is not available for Leap 15.0 Beta:
An excerpt of the package description:
"OpenSC provides a set of utilities to access smart cards. It mainly focuses on cards that support cryptographic operations. It facilitates their use in security applications such as mail encryption, authentication, and digital signature. OpenSC implements the PKCS#11 API. Applications supporting this API, such as Mozilla Firefox and Thunderbird, can use it."
Tumbleweed currently has opensc 0.17.0 - the latest stable version, released on 18.07.2017, according to the OpenSC wiki:
Leap 42.3 has opensc 0.13.0.
Leap 42.2, Leap 42.1 and openSUSE 13.2 had opensc 0.13.0.
Was opensc dropped on Leap 15.0?
