|  |  | 
|  | openssl-env - OpenSSL environment variables | 
|  |  | 
|  | =head1 DESCRIPTION | 
|  |  | 
|  | The OpenSSL libraries use environment variables to override the | 
|  | compiled-in default paths for various data. | 
|  | To avoid security risks, the environment is usually not consulted when | 
|  | the executable is set-user-ID or set-group-ID. | 
|  |  | 
|  | =over 4 | 
|  |  | 
|  | =item B<CTLOG_FILE> | 
|  |  | 
|  | Specifies the path to a certificate transparency log list. | 
|  | See L<CTLOG_STORE_new(3)>. | 
|  |  | 
|  | =item B<OPENSSL> | 
|  |  | 
|  | Specifies the path to the B<openssl> executable. Used by | 
|  | the B<rehash> script (see L<openssl-rehash(1)/Script Configuration>) | 
|  | and by the B<CA.pl> script (see L<CA.pl(1)/NOTES> | 
|  |  | 
|  | =item B<OPENSSL_CONF>, B<OPENSSL_CONF_INCLUDE> | 
|  |  | 
|  | Specifies the path to a configuration file and the directory for | 
|  | included files. | 
|  | See L<config(5)>. | 
|  |  | 
|  | =item B<OPENSSL_CONFIG> | 
|  |  | 
|  | Specifies a configuration option and filename for the B<req> and B<ca> | 
|  | commands invoked by the B<CA.pl> script. | 
|  | See L<CA.pl(1)>. | 
|  |  | 
|  | =item B<OPENSSL_ENGINES> | 
|  |  | 
|  | Specifies the directory from which dynamic engines are loaded. | 
|  | See L<openssl-engine(1)>. | 
|  |  | 
|  | =item B<OPENSSL_MALLOC_FD>, B<OPENSSL_MALLOC_FAILURES> | 
|  |  | 
|  | If built with debugging, this allows memory allocation to fail. | 
|  | See L<OPENSSL_malloc(3)>. | 
|  |  | 
|  | =item B<OPENSSL_MODULES> | 
|  |  | 
|  | Specifies the directory from which cryptographic providers are loaded. | 
|  | Equivalently, the generic B<-provider-path> command-line option may be used. | 
|  |  | 
|  | =item B<OPENSSL_WIN32_UTF8> | 
|  |  | 
|  | If set, then L<UI_OpenSSL(3)> returns UTF-8 encoded strings, rather than | 
|  | ones encoded in the current code page, and | 
|  | the L<openssl(1)> program also transcodes the command-line parameters | 
|  | from the current code page to UTF-8. | 
|  | This environment variable is only checked on Microsoft Windows platforms. | 
|  |  | 
|  | =item B<RANDFILE> | 
|  |  | 
|  | The state file for the random number generator. | 
|  | This should not be needed in normal use. | 
|  | See L<RAND_load_file(3)>. | 
|  |  | 
|  | =item B<SSL_CERT_DIR>, B<SSL_CERT_FILE> | 
|  |  | 
|  | Specify the default directory or file containing CA certificates. | 
|  | See L<SSL_CTX_load_verify_locations(3)>. | 
|  |  | 
|  | =item B<TSGET> | 
|  |  | 
|  | Additional arguments for the L<tsget(1)> command. |
