Revision 1.13, Mon Jan 10 12:17:49 2022 UTC (2 years, 4 months ago) by tb
Branch: MAIN
Changes since 1.12: +17 -2 lines
Implement openssl pkey -{,pub}check and pkeyparam -check
These expose EVP_PKEY_{,public_,param_}check() to the command line.
They are currently noops and will be enabled in the upcoming bump.
