On Openpgp.js, in order to generate the encryption keys, the name and the email properties are mandatory:

await generateKey({ curve: 'brainpoolP512r1',  userIDs: [{ name: 'Test', email: 'test@test.com' }] });

In a project I'd like to use OpenPGP for a different scenario where there will be no name or email, each pair of keys would be linked to an internal id in the database.

In this project I just need to encrypt and sign messages.

My question is: Is OpenPGP best suited for just signing and encrypting messages with out any user information?
