Data Encryption

Data encryption is the process of converting information into an unreadable coded format using a cryptographic algorithm and a secret key. Only authorized parties who possess the correct decryption key can convert the data back into its original, readable form. Encryption protects data both in transit (while moving across networks) and at rest (while stored on servers or devices).

Digital publications often contain proprietary content, customer data collected through lead-capture forms, or payment information from document sales. Without encryption, this data is vulnerable to interception and theft. Strong encryption ensures that even if an attacker gains access to the raw data, they cannot read or use it, keeping your business and your audience protected.

FlipLink uses HTTPS (TLS encryption) for all connections between readers and the platform, meaning every page view, form submission, and file download is encrypted in transit. Data stored on FlipLink's servers, including uploaded PDFs, collected leads, and account credentials, is encrypted at rest. When you enable [password protection](/features/password-protection) on a publication, the access credentials are hashed and stored securely. For publications sold through FlipLink's Stripe integration, all payment processing occurs over Stripe's PCI-compliant encrypted infrastructure, so card details never touch FlipLink's servers directly.

A healthcare company publishes an internal compliance handbook as a password-protected FlipLink flipbook. The PDF content, the passwords set by administrators, and the viewer activity logs are all encrypted, ensuring that sensitive organizational policies remain confidential even if the underlying storage were compromised.
