====== Generating a Self-Signed SSL Certificate ======

**Command:** The following command generates a self-signed key and certificate interactively.

===== Command Details: =====

To generate a self-signed SSL certificate with OpenSSL, use the following command:

<code bash>
openssl req -x509 -newkey rsa:4096 -keyout Selfsigned_key.pem -out Selfsigned_cert.pem -sha256 -days 3650 -nodes
</code>

**Explanation of the command:**

  * **req:** This option initiates a certificate signing request (CSR).
  * **-x509:** This option outputs a self-signed certificate instead of a CSR.
  * **-newkey rsa:4096:** This option generates a new RSA key of 4096 bits.
  * **-keyout Selfsigned_key.pem:** This option specifies the filename to write the newly created private key to.
  * **-out Selfsigned_cert.pem:** This option specifies the filename to write the newly created certificate to.
  * **-sha256:** This option specifies the use of SHA-256 for signing the certificate.
  * **-days 3650:** This option sets the certificate to be valid for 3650 days (10 years).
  * **-nodes:** This option tells OpenSSL not to encrypt the private key.

By running this command, you will generate a self-signed SSL certificate along with a private key that is not encrypted.
