Necessity

The use of self-signed certificates is most commonly used for: Application Testing
Developers often use self-signed certificates for testing applications before their publication. This allows them to create a secure connection, for example, between the application and the server, without the need to purchase a certificate from a certification authority. Internal Use
In some companies, self-signed certificates are used within internal networks to encrypt data and ensure security.

Risks and Limitations

The use of self-signed certificates carries certain risks and difficulties in their use. Key risks include:

  • System distrust.

Since self-signed certificates are not verified and not issued by certification authorities, they often trigger security warnings in browsers and applications. This can alarm users.

  • Vulnerability of each certificate.

The use of self-signed certificates can increase the risk of attacks such as "man-in-the-middle" (MITM), where a malefactor can intercept data between two parties.

MITM is a "man-in-the-middle" attack — a cyber attack in which a cybercriminal intercepts data being sent between two organizations or people. The purpose of the interception is to steal, eavesdrop, or alter data for some malicious purpose, such as extortion.
