E2EE
Encryption
Abbreviation for end-to-end encryption; ensures confidentiality between endpoints.
Definition
E2EE is a cryptographic property where plaintext is only available at the communicating endpoints. Intermediaries (servers, ISPs) relay ciphertext. Note: metadata (who/when) may still be visible.
In plain English
Abbreviation for end-to-end encryption; ensures confidentiality between endpoints.
Why this matters
Why it matters: E2EE reduces provider access to content, limiting exposure from breaches or insider access, but does not eliminate metadata-based tracking.
Example
Example: E2EE in messaging protects message bodies, while contact discovery and delivery timing may still generate metadata.
