Revision 1.37, Fri Jan 26 11:58:37 2024 UTC (3 months, 3 weeks ago) by job
Branch: MAIN
CVS Tags: OPENBSD_7_5_BASE, OPENBSD_7_5, HEAD
Changes since 1.36: +50 -12 lines
Add 'openssl x509 -new' functionality to the libcrypto CLI utility
The ability to generate a new certificate is useful for testing and
experimentation with rechaining PKIs.
While there, alias '-key' to '-signkey' for compatibility.
