+=head1 NAME
+
+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. Only used by
+the B<rehash> script.
+See L<openssl-rehash(1)/Script Configuration>.
+
+=item B<OPENSSL_CONF>
+
+Specifies the path to a configuration file.
+See L<openssl(1)> and L<config(5)>.
+
+=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<OPENSSSL_malloc(3)>.
+
+=item B<OPENSSL_MODULES>
+
+Specifies the directory from which cryptographic providers are loaded.
+See L<openssl-provider(1)>.
+
+=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.
