Revision ae6b654b669638882a6ddce012ff55adc7cf6a82 authored by Richard Levitte on 18 April 2020, 10:14:41 UTC, committed by Richard Levitte on 19 April 2020, 21:34:05 UTC
We have copies of the exact same fipsinstall call in several test recipes. This refactors those calls into a single simple script. Reviewed-by: Paul Dale <paul.dale@oracle.com> (Merged from https://github.com/openssl/openssl/pull/11565)
