If used this option mustprecede and -algorithm, -paramfile or -pkeyopt options. Generate a set of parameters instead of a private key. See KEY GENERATION OPTIONS below for more details. The precise set ofoptions supported depends on the public key algorithm used and itsimplementation. Set the public key algorithm option opt to value. The options -paramfile and -algorithmare mutually exclusive. If used this option mustprecede any -pkeyopt options. Public key algorithm to use such as RSA, DSA or DH. If used this option should precede all otheroptions. The engine will then be set as the defaultfor all available algorithms. Specifying an engine (by its unique id string) will cause genpkeyto attempt to obtain a functional reference to the specified engine,thus initialising it if needed. Any algorithmname accepted by EVP_get_cipherbyname() is acceptable such as des3. This option encrypts the private key with the supplied cipher. For more information about the format of argsee the PASS PHRASE ARGUMENTS section in openssl.

This specifies the output format DER or PEM. If this argument is not specified then standard output isused.

The genpkey command generates a private key. Openssl Rsa Key Generation C Definition.This article helps you as a quick reference to understand OpenSSL commands which are very useful in common, and for everyday scenarios especially for system administrators. OpenSSL is a CLI (Command Line Tool) which can be used to secure the server to generate public key infrastructure (PKI) and HTTPS.
