## What you need to know

### What is encryption?

Encryption transforms readable data into protected ciphertext that requires an authorized key to recover. It reduces exposure but does not replace access control or minimization.

### What does encryption in transit mean?

Encryption in transit protects data while it moves between browsers, services and networks, commonly through TLS. Both endpoints still need protection.

### What does encryption at rest mean?

Encryption at rest protects stored data on disks, databases, backups or devices. Key access and application permissions determine how much protection it provides.

### Encryption at rest vs in transit: what's the difference?

In-transit encryption protects communication; at-rest encryption protects stored copies. Ecommerce systems commonly need both because data moves and persists.

### What ecommerce data should be encrypted?

Encrypt sensitive personal, credential, payment-related, secret and backup data according to classification and risk. Some public catalog content may not need confidentiality.

### What is HTTPS?

HTTPS is HTTP carried through TLS, providing encrypted communication and server authentication for web traffic when configured correctly.

### Why does ecommerce need HTTPS?

HTTPS helps prevent interception and modification of sign-in, checkout, and browsing traffic. Use it across the entire store, not only the payment page.

### What is an SSL/TLS certificate?

An SSL/TLS certificate binds a domain to a public key and lets browsers validate the server during a secure connection. Monitor issuance, renewal, and domain coverage.

### A quick store check

Confirm HTTPS across storefront and admin routes, certificate monitoring, protected storage and key-management ownership.

## Frequently asked questions

### Does encryption make customer exports safe to email?

Not by itself. Use an approved secure transfer method, access controls, expiration, and minimum necessary fields.

### Can an expired certificate expose checkout?

It can block trusted connections and sales; monitor renewal and test every relevant domain.
