CoreCrypto client which manages one cryptographic client for proteus and MLS.

A Client identifier

A unique identifier for clients. A client is an identifier for each App a user is using, such as desktop, mobile, etc. Users can have multiple clients. More information here

A unique identifier for a single conversation.

The backend provides an opaque string identifying a new conversation. Construct an instance of this newtype to pass that identifier to Rust.

CoreCrypto wraps around MLS and Proteus implementations and provides a transactional interface for each.

The CoreCryptoContext holds the primary CoreCrypto APIs.

An instance of this struct is provided to the function handed to CoreCrypto::transaction.

Every mutable operation is done through this struct. This struct will buffer all operations in memory and when [TransactionContext::finish] is called, it will persist the data into the keystore.

This trait is used to provide a callback mechanism to hook up the respective platform logging system.

The key used to encrypt the database.

Wire end to end identity solution for fetching a x509 certificate which identifies a client.

See [core_crypto::e2e_identity::E2eiEnrollment]

An EpochObserver is notified whenever a conversation’s epoch changes.

The raw public key of an external sender.

This can be used to initialize a subconversation.

MLS Group Information

This is used when joining by external commit. It can be found within the GroupInfoBundle within a CommitBundle.

An HistoryObserver is notified whenever a new history client is created.

A signed object describing a client’s identity and capabilities.

Includes a public key that can be used to encrypt to that client. Other clients can use a client’s KeyPackage to introduce that client to a new group.

Used by core crypto to send commits or application messages to the delivery service. This trait must be implemented before calling any functions that produce commits.

A secret key derived from the group secret.

This is intended to be used for AVS.

A TLS-serialized Welcome message.

This structure is defined in RFC 9420: https://www.rfc-editor.org/rfc/rfc9420.html#joining-via-welcome-message.
