This is documented in the c_rehash manpage included in OpenSSL (in doc/apps/c_rehash.pod before compiling). If a single /etc/cert directory is shared by OpenSSL 0.9.x and OpenSSL 1.0.x, you will need symlinks for both the old and new digest formulas. Like this: c_rehash /etc/certs # Only do this second step if OpenSSL 0.9.x is sharing the directory with 1.0.x # (Situation with OpenSSL 1.1.x is unknown): c_rehash -n -old /etc/certs Enjoy Jakob -- Jakob Bohm, CIO, Partner, WiseMo A/S. https://www.wisemo.com Transformervej 29, 2860 S?borg, Denmark.
