DESCRIPTION
Header "DESCRIPTION" This command is used to print out version information about OpenSSL.
OPTIONS
Header "OPTIONS" -help 4
Item "-help" Print out a usage message.
-a 4
Item "-a" All information, this is the same as setting all the other flags.
-v 4
Item "-v" The current OpenSSL version.
-b 4
Item "-b" The date the current version of OpenSSL was built.
-o 4
Item "-o" Option information: various options set when the library was built.
-f 4
Item "-f" Compilation flags.
-p 4
Item "-p" Platform setting.
-d 4
Item "-d" OPENSSLDIR setting.

-r 4
Item "-r" The random number generator source settings.
-c 4
Item "-c" The OpenSSL CPU settings info.
-w 4
Item "-w" The OpenSSL OSSL_WINCTX build time variable, if set.
Used for computing Windows registry key names. This option is unavailable on
non-Windows platforms.
HISTORY
Header "HISTORY" In OpenSSL versions prior to 3.4, OpenSSL had a limitation regarding the
\fBOPENSSLDIR, MODULESDIR and ENGINESDIR build time macros. These macros
were defined at build time, and represented filesystem paths. This is common
practice on unix like systems, as there was an expectation that a given build
would be installed to a pre-determined location. On Windows however, there is
no such expectation, as libraries can be installed to arbitrary locations.
\fBOSSL_WINCTX was introduced as a new build time variable to define a set of
registry keys identified by the name openssl-<version>-<ctx>, in which the
<version> value is derived from the version string in the openssl source, and
the <ctx> extension is derived from the OSSL_WINCTX variable. The values of
\fBOPENSSLDIR, ENGINESDIR and MODULESDIR can be set to various paths
underneath this key to break the requirement to predict the installation path at
build time.
NOTES
Header "NOTES" The output of \*(C`openssl version -a\*(C' would typically be used when sending
in a bug report.
