Recent CIA leaks have proven that no one is immune to fraud attacks. Important documents and photos are transmitted via email, and encryption of emails is used to secure such conversations.
Nowadays, you don't need to learn cryptography to protect your data. There are popular services and extensions that encrypt your emails in real-time, thereby protecting them from penetration by Internet fraudsters.

For encryption, the AES-256 algorithm is used. ProtonMail is an intermediary between the sender and the recipient of an email. For this reason, both parties must be registered with the service. The sender sends an email, and the recipient receives only a link to the service they should use to read it. To read an encrypted email, you must enter two passwords, one to log into the service and one to read the email. The service is free, but you can use its extended version by paying 48€ per year.
