NAME

       openssl-version - print OpenSSL version information

SYNOPSIS

       openssl version [-help] [-a] [-v] [-b] [-o] [-f] [-p] [-d] [-e] [-m] [-r] [-c] [-w]

DESCRIPTION

       This command is used to print out version information about OpenSSL.

OPTIONS

       -help
           Print out a usage message.

       -a  All information, this is the same as setting all the other flags.

       -v  The current OpenSSL version.

       -b  The date the current version of OpenSSL was built.

       -o  Option information: various options set when the library was built.

       -f  Compilation flags.

       -p  Platform setting.

       -d  OPENSSLDIR setting.

       -e  ENGINESDIR settings.

       -m  MODULESDIR settings.

       -r  The random number generator source settings.

       -c  The OpenSSL CPU settings info.

       -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

       In OpenSSL versions prior to 3.4, OpenSSL had a  limitation  regarding  the  OPENSSLDIR,  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.  OSSL_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 OPENSSLDIR, 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

       The output of "openssl version -a" would typically be used when sending in a bug report.
