End-to-End Encryption
A communication security mechanism ensuring that messages can only be decrypted and read by the two endpoints of a conversation, with service providers unable to access plaintext content. It is the core security technology used by mainstream messaging applications such as Signal and WhatsApp.

If a screen sharing tool uses a server-relay architecture and has not deployed E2EE, the vendor can theoretically access the screen content in transit.
End-to-end encryption protects message content but not metadata (such as the communicating parties, time, message length and frequency), and metadata may still be collected by the platform or provided to law enforcement under law.
For end-to-end encrypted and decentralized applications, the compliance requirement to trace the first originator is technically nearly impossible to fulfill.
The security of E2EE is highly dependent on the quality of key management implementation, including details such as device pairing methods, key derivation algorithms, and whether forward secrecy is supported.
Key points for verifying products that claim to support E2EE include whether keys are generated locally, whether the product is open-source and auditable, and whether the key negotiation process has undergone an independent security audit.
ButterShare claims to provide end-to-end encryption.
Military-grade encrypted communication devices typically remove functions such as location tracking, cameras, and microphones found in standard operating systems, retaining only end-to-end encrypted messaging capabilities, paired with mechanisms such as remote wipe and duress passwords.
AI conversation management tools need to address data privacy and security issues, and common industry practices include end-to-end encryption, zero-knowledge proofs, and local-first architecture.
End-to-end encryption makes email content invisible to servers, which affects features such as full-text search, spam filtering, and content auditing.
After end-to-end encryption, email content is invisible to servers, which affects functions such as full-text search, spam filtering, and content auditing.
