What Is Content Encryption in a CMS?
BeginnerQuick Answer
TL;DR
Content encryption in a CMS protects stored content by converting it into unreadable ciphertext that can only be decrypted with the correct key. There are two types: encryption in transit (HTTPS/TLS protecting data as it moves between browser and server) and encryption at rest (protecting data stored in the database and file system). Most modern CMS platforms handle encryption in transit automatically via HTTPS. Encryption at rest varies—SaaS CMS platforms typically include it; self-hosted CMS platforms require you to configure it at the database or disk level.
Key Takeaways
- Encryption in transit (HTTPS/TLS) protects data moving between users and the CMS—this is mandatory for all websites
- Encryption at rest protects stored data in databases and file systems—important for sensitive content
- SaaS CMS platforms (Sanity, Contentful) typically encrypt data at rest by default using AES-256
- Self-hosted CMS platforms require you to configure encryption at the database or disk level
- End-to-end encryption (where only the content owner can decrypt) is rare in CMS platforms due to search and query requirements
