Allow exporting encrypted ED25519 keys.
The crypt flag was disallowed to support SSH2 export.
But since the SSH2 key is written unencrypted,
this restriction makes no sense anymore.
Generalize the Clipboard format selection
and extend it to certificates.
Certificates may now be exported as chain
or together with private key.
The clipboard format selection also
affects the Drag&Drop content.
The Export->Clipboard men now also shows the
currently selected format export.
The ta-key will be generated on-demand and assigned to the
issuing CA. All issued certificates of this CA will use the
same ta-key.
It can be exported as single file and will also be part of the
exported openvpn configuration file.
Extend export tests to validate the output of ta-keys
and adapt the OpenVPN conf file export test to also check the ta-key.
Before this change, the export format descriptions were created
statically before any translation has been setup.
Now it is created after the translation is setup and after every
language change.
Create ovpn file with "ca", "cert" and "key"
Additionally put all intermediate CAs (if any)
tagged as "extra-certs".
"tls-auth" "OpenVPN Static key V1" not supported (yet)
Extend export-test by OpenVPN test case
When XCA started in 2002, there were no C++ initializers.
Drop explicit initializers from the constructors.
- Fix indentations of section declarators.
- Replace NULL by nullptr when feasible.
- Sort private section: properties first, then methods.
Fix logical error when exporting in PEM format.
The key export part was not reached...
The diff is much smaller when displayed with -b to skip
indentation-only changes....
Drop the unused "F_PLUSKEY" flag and fix the Template export
Collect all export formats in pki_export.
Each export format has assigned acouple of flags, indicating,
whether they are text, concatenateable, encrypted, usable for
multiple selections or only for a single item.
