SFrame.ts

Typescript library implementing the SFrame end to end encryption based on webcrypto.

Differences from the sframe draft

• ratcheting is not implemented
• keyIds are used as senderIds
• IV contains the keyId and the frame counter to ensure uniquenes when using same encryption key for all participants

Keying

This library does not provide any keying mechanism, but it must be provide by the application instead.

Unlike the sframe draft, this library requires each participant to have a numeric senderId that will be used as keyId in the sframe header.

Example

Check the example directory for a loopback example implementation.
