//! Mobile specific crypto operations
//!
//! This module contains temporary code for handling mobile specific cryptographic operations until
//! the SDK is fully implemented. When porting functionality from `client` the mobile clients should
//! be updated to consume the regular code paths and in this module should eventually disappear.
