OPENSSL-VERSION(1ossl)              OpenSSL             OPENSSL-VERSION(1ossl)



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.
