=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.

|
|
|
|
|
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.
