# This policy follows the BSI TR-02102-2 "Kryptographische Verfahren: Verwendung von Transport Layer Security (TLS)"
# Generic:https://www.bsi.bund.de/SharedDocs/Downloads/DE/BSI/Publikationen/TechnischeRichtlinien/TR02102/BSI-TR-02102.html
# TLS: https://www.bsi.bund.de/SharedDocs/Downloads/DE/BSI/Publikationen/TechnischeRichtlinien/TR02102/BSI-TR-02102-2.html
# IPSEC: https://www.bsi.bund.de/SharedDocs/Downloads/DE/BSI/Publikationen/TechnischeRichtlinien/TR02102/BSI-TR-02102-3.html
# Note that currently crypto-policies do not adjust ipsec configs, but only openssl or nss.
# SSH: https://www.bsi.bund.de/SharedDocs/Downloads/DE/BSI/Publikationen/TechnischeRichtlinien/TR02102/BSI-TR-02102-4.html
# Note that the SUSE openssh is not yet reading crypto policies.
