Frequently Asked Questions

Find Quick Answers

What is a self-signed SSL certificate?

A self-signed SSL certificate is a digital certificate that is signed by the same entity whose identity it certifies, rather than by a trusted certificate authority (CA). It provides encryption but browsers will show security warnings because it's not verified by a trusted third party.

What are self-signed certificates used for?

Self-signed certificates are commonly used for development and testing environments, internal networks, IoT devices, and applications where you don't need public trust but still require encrypted communication.

Can I use this for production websites?

No, self-signed certificates are not recommended for production websites. For public-facing websites, you should obtain certificates from trusted certificate authorities like Let's Encrypt, DigiCert, or GlobalSign to avoid browser security warnings.

What's the difference between RSA and ECDSA?

RSA (Rivest-Shamir-Adleman) is a widely-used asymmetric encryption algorithm that's compatible with most systems. ECDSA (Elliptic Curve Digital Signature Algorithm) provides similar security with smaller key sizes, resulting in faster performance and smaller certificates.
