Lacre does require you to understand the basics in order to use it without compromising security. It is built in a way that hides the encryption from users. However, it is better to understand what is happening. It empowers us all when realizing that there is no magic trickery, the concept is simple and you are in the front seat.
Here is a [Video](https://invidious.snopyta.org/watch?v=E5FEqGYLL0o?target=_blank) explaining the basic concept of encryption.

GPG (GNU Privacy Guard) is one of the most popular encryption methods to secure email correspondance and files between people. GnuPG uses asymmetric encryption technology. It means you create two types of keys. Secret and public key. Public key is used by others to encrypt messages to you. You can (and should) share that key with everyone you want to secure your communication with. There are even special public servers called "keyservers" where you can post your key so that anyone could obtain it. The second key is your Secret (private) key. This key is used to decrypt emails addressed to you. Loosing or sharing this key with others will result in either loosing access to your emails or allowing others to read your private emails. It is therefore essential to never share this key with anyone and to keep a backup copy of it.
