Revision 1.13, Mon Sep 21 13:13:06 2015 UTC (8 years, 8 months ago) by bcook
Branch: MAIN
Changes since 1.12: +1 -4 lines
remove vestigial bits of sha-0 and md2 from openssl(1)
Noted by kinichiro on github. We probably need a better way to indicate the
list of message digests that are allowed, as the current ones are nowhere near
exhaustive (sigh - guenther@)
