Handling Self-Signed Certificate Warnings

Self-signed certificates lack third-party validation, triggering security warnings in all browsers. While acceptable for development, production sites require CA-issued certificates. For internal applications, consider creating private CAs:

# Create private CA
openssl genrsa -out ca.key 4096
openssl req -new -x509 -days 3650 -key ca.key -out ca.crt

# Sign server certificate
openssl x509 -req -days 365 -in server.csr -CA ca.crt -CAkey ca.key -CAcreateserial -out server.crt

# Distribute ca.crt to client systems
# Windows: certutil -addstore "Root" ca.crt
# Linux: cp ca.crt /usr/local/share/ca-certificates/ && update-ca-certificates
