Generate self-signed SSL/TLS certificates online with RSA and ECDSA algorithms
Add multiple domains including wildcards (e.g. *.example.com)
Self-signed SSL certificates are certificates that you create and sign yourself, rather than being issued by a trusted Certificate Authority (CA). They are suitable for development, testing environments, or internal networks. While self-signed certificates provide encryption, browsers will display security warnings because they are not issued by a trusted CA.
