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.
