This is due to the fact that some SSL programming libraries require that. In a nutshell, OpenSSL toolkit implements the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols with full-strength cryptography. [-fingerprint] always valid because some cipher suites use the key for digital signing. but are described in the TRUST SETTINGS section.

This article describes a step by step procedure from scratch on how to generate a server-side X509 certificate on Windows 7 for SSL/TLS TCP communication using OpenSSL. the value used by the ca utility, equivalent to no_issuer, no_pubkey, can thus behave like a "mini CA".
