Description
The "Mail X.420" or "ERP/1: Documents" system fully complies with corporate requirements, industry standards and national legislation.
It is built on the Ericsson Erlang/OTP platform, designed for high-load environments and mission-critical applications.
The client works completely offline and is developed in SwiftUI to ensure maximum battery life in field conditions. Protocol messages are serialized using DER X.690 encoding — the same standard used in TLS certificates. Every message is end-to-end encrypted and routed through a chain of secure brokers that are an integral part of the system.
