[Feature Request]: Email address obfuscation/encryption

[brzGatsu]

Feature Description

It would be great to have a builtin email-address obfuscation/encryption as spam-prevention.

Here are some common techniques: https://www.ionos.com/digitalguide/e-mail/e-mail-security/protecting-your-email-address-how-to-do-it/

I personally like the javascript/rot13 solution but with a random rotation, not 13. It can be combined with hex entity conversion as well.

Captcha would in most cases require an external provider which is problematic in terms of gdpr.
