Data Encryption

Euron Systems employs industry-standard encryption to protect all data across the platform. This document covers our encryption practices for data at rest and data in transit.

Data in Transit

All data transmitted between users and the Euron Systems platform is encrypted:

TLS 1.3 — The latest version of Transport Layer Security
HTTPS Everywhere — All pages served over HTTPS
HSTS — HTTP Strict Transport Security headers enforced
Certificate Pinning — Prevents man-in-the-middle attacks on mobile apps
Perfect Forward Secrecy — Each session uses unique encryption keys

Data at Rest

Data stored in our databases and file storage is encrypted:

AES-256 Encryption — All sensitive data is encrypted at rest using AES-256
Database Encryption — Full-disk encryption on all database servers
File Storage — All uploaded files are encrypted on the storage layer
Backup Encryption — All backups are encrypted with separate keys

What's Encrypted

Data Type	Encryption
Student PII (name, email, phone)	AES-256
Payment information	Tokenized (never stored directly)
Passwords	bcrypt with salt (one-way hash, not reversible)
API keys and secrets	AES-256 with key rotation
Video content	AES-128 (DRM encryption)
Documents and files	AES-256 at storage level
Database backups	AES-256

Key Management

Encryption keys are managed using industry-standard key management services.
Keys are rotated regularly (every 90 days for data-at-rest keys).
Access to keys is restricted to authorized personnel only.
Key usage is logged and audited.

Payment Security

Payment data is handled with the highest security standards:

PCI DSS Compliant — Euron Systems is PCI DSS compliant for payment processing
Tokenization — Card numbers are tokenized by the payment gateway; raw card data never touches our servers
3D Secure — Additional authentication layer for card payments

Video DRM — Video encryption
GDPR Compliance — Data protection regulation
Watermarking — Content protection
