Encryption is one of the methods of modern cryptography that encrypts information so that only a certain number of users can access it. Various services, regardless of the type of activity, use encryption methods to protect their data. The most common way to transfer data is a simple email that only the sender and recipient can read. The encryption methods used prevent malicious users from gaining access to the data in the message.
There are two main types of encryption:
Symmetric or private encryption uses the same key to encode and decode text. Since both sides of the communication have a key that opens access to encryption, this method is additionally called shared secret encryption. This is the best option for secure data transmission, in case of transferring a large amount of data, since the user does not need to spend additional time for encryption and decryption.
Open-type or asymmetric encryption appeared not so long ago and, unlike private encryption, uses two keys. The first of the closed type is known exclusively to the owner of the message, while the second is available to everyone and can be used to encrypt simple messages. The private key is relevant when decrypting a received message as needed. Asymmetric encryption allows users to exchange data without exchanging the keys themselves from the user's devices.
Regardless of the chosen method of data protection in the exchange process, you get the following benefits:
You can encrypt your personal files and emails when needed. You can install data protection software at any time, especially if an unlimited number of people have access to the computer. The mail client is engaged in the protection of correspondence, the most important thing is not to transfer the password from your personal account to third parties.
