For those of you familiar with Light's Hope export tool, we offer a similiar feature. Excalibur's players can download their character data in a json file with an included signature that a third party can validate to guarantee data authenticity.
For those familiar with MaNGOS/TrinityCore, the following table records are included
To verify characters you need to do the following actions
openssl dgst -sha512 -verify <(openssl x509 -in "exwow_public.crt" -pubkey -noout) -signature signature.sha512 characters.json
Maybe not everyone wishes to import our characters directly in their original form, you can freely pick & match the aspects that you wish to import and exclude elements you do not consider a match for your server. Or use this zip as a way to validate a registration bonus.
Any implementation questions can be directed at [email protected]. Any server implementing this method will be advertised on our facebook page.
