In the context of blockchain, decentralization is a core principle that ensures the network operates without a central authority, enhancing security, transparency, and trust. Key management and functionality are critical components of this decentralized structure, leveraging cryptographic principles to maintain the integrity and authenticity of the blockchain. Here's an in-depth look at key decentralization and its functionality in blockchain technology.

To encrypt a FreeBSD system using Geli (FreeBSD's disk encryption mechanism), follow these steps:

Prepare the FreeBSD Installation:

Start by booting into the FreeBSD installation media.
Proceed through the installation process until you reach the disk partitioning step.

 Partition Your Disk:

Select the disk you want to install FreeBSD on.
Create partitions as needed. Typically, you'll want a separate partition for /boot and the rest for the root filesystem .

Encrypt the Partitions:
