How the Internet Stays Secure (Certificates) – Explained in Rap Form

Lyrics:

Keys in the system, trust in the hand,
Certificates guide what machines understand.
Public and private, a pair of two,
One locks the message, the other breaks through.

Signed with authority, trusted and clear,
A chain of providers that all must appear.
Root at the top, the base of the tree,
Without that anchor no trust can be.

Browsers check when a site makes a call,
Is the cert valid, trusted by all?
Dates must be current, names must align,
If it’s expired, the warning will shine.

Encryption is strong, the channel is tight,
TLS handshakes secure day and night.
Keys are exchanged, the secret is made,
Packets encrypted so data is safe.

Certificates live on servers and more,
Protecting the emails, the apps that explore.
Code signed scripts ensure they’re true,
Not changed by attackers who slipped it through.

But if one leaks or a key is exposed,
The chain breaks down, the trust is closed.
Admins revoke, the CRL grows,
New certs replace what everyone knows.

Think of an ID you show at the gate,
Proving your name, your status, your state.
Certificates work in the very same way,
Proof of identity every day.

Keys in the system, trust in the hand,
Certificates guide what machines understand.
Public and private, a pair of two,
One locks the message, the other breaks through.
