Core ID
Core ID is an optional 44-character identifier that can add sender identity context to an email. It is generated by the CorePass app. OpenPGP/GPG—not Core ID—encrypts the message content.
Email headers
The system is checking the email headers for presence of the Core ID. If the Core ID is not present in the email headers, the email will continue with next checks.
The key servers
If you want to send an email to someone with an Onion Email address, you need to encrypt the message with the receiver's public key. You can find the key in the public key database, such as keys.openpgp.org or pgp.mit.edu. Otherwise, ask the receiver about their public key.
