In a different Question, in the first answer is written that some meta data doesn't get encrypted.




What you shouldn't forget about encrypted e-mail, is that while the message body is properly encrypted, some meta data like the subject, sender or receiver aren't.




What is the reason that Proton Mail doesn't encrypted some meta data?

          Proton Mail uses an encryption format called OpenPGP. It is only designed to encrypt the message. Unless the subject is put in the message and the subject field is left blank, the subject will be kept unencrypted. The e-mail sender and receiver fields, on the other hand, need to be unencrypted for proper routing to occur. This is all a limitation in the design of e-mail, a default unencrypted system.

This Kransekake is a traditional Scandinavian baker's confection. Confectionery is the art of making confections , which are food items that are rich in sugar and carbohydrates. Exact definitions are difficult. [1] In general, though, confectionery is divided into two broad and somewhat overlapping categories, bakers' confections and sugar confections. [2] Bakers' confectionery, also called flour confections , includes principally sweet pastries, cakes, and similar baked goods.
