## 3. Generate and use Self-signed Keys and Certificates with MinIO

This section describes how to generate a self-signed certificate using various tools:

* 3.1 [Use certgen to Generate a Certificate](#using-go)
* 3.2 [Use OpenSSL to Generate a Certificate](#using-open-ssl)
* 3.3 [Use OpenSSL (with IP address) to Generate a Certificate](#using-open-ssl-with-ip)

   * metadata this will fail with an exception.

## Check the username { #check-the-username }

Here's a more complete example.

Use a dependency to check if the username and password are correct.

For this, use the Python standard module [`secrets`](https://docs.python.org/3/library/secrets.html) to check the username and password.

## Decision

We do not use Java serialization.
Instead, we use custom serialization where we explicitly describe how data objects should be serialized and deserialized.

For internal purposes, we use binary formats for their brevity.
We use the `Serializer` abstraction to separate the actual implementation of serialization from its uses.

When sharing data with external tools, we use JSON.
