AleHu is an open source encrypted message transfer system that encompasses both server (PHP) and client software (Java).

Before sending messages, an AleHu client registers itself at the AleHu server with its public key. Thus, an AleHu client can communicate fully anonymously with other AleHu clients. The AleHu server has no idea who is sending messages to whom.

Messages are split by the client into packets that are sent to the AleHu server where they are consumed by the receiver and assembled after reception. Consequently, you can send unlimited (except for hardware and OS constraints) messages.

Packet reception is acknowledged by the receiver so the sender has full confidence that a message has been (completely) transmitted.

Each message to the AleHu server is digitally signed by the sender and checked by the server and the receiver.

Spam is impossible since a client only accepts messages from senders whose public keys have been previously imported by the receiver.
