How to Download IP Messenger: A Secure and Free LAN Messaging Software
If you are looking for a simple, lightweight, and secure way to communicate with your friends or colleagues on a local area network (LAN), you might want to try IP Messenger. IP Messenger is a pop-up style LAN messaging software that does not require a server and uses TCP/IP (UDP) protocol. It is based on open-source technology and offers features such as file/folder transfer, inline image capture, message encryption, and powerful log viewer. In this article, we will show you how to download and install IP Messenger for Windows, and how to use it for LAN communication.
What is IP Messenger and why use it?
IP Messenger is a free software that was developed by SHIROUZU Hiroaki, a Japanese programmer, in 1996. It is widely used by Japanese companies and their affiliates for internal communication. It has also been ported to other platforms such as MacOS X, Linux, Android, Java, and KDE. Here are some of the reasons why you might want to use IP Messenger:

IP Messenger features
Auto member detection over router: IP Messenger can automatically detect other users on the same network, even if they are behind routers or firewalls. You can also use the Member Master mode to enable auto member detection over routers.
High speed file/folder transfer: IP Messenger allows you to transfer files and folders with other users by simply dragging and dropping them to the send window. You can also resume interrupted transfers or cancel them at any time.
Inline image that is captured from desktop: IP Messenger lets you capture any part of your desktop screen and send it as an inline image in your message. You can also edit the image before sending it, such as adding annotations or cropping it.
Safety message communication (RSA2048bit + AES256bit): IP Messenger encrypts your messages with RSA2048bit public key encryption and AES256bit symmetric key encryption. You can also sign or verify your messages with PKCS#1-v1_5 digital signature algorithm.
Powerful log viewer (v4.0 or later): IP Messenger has a built-in log viewer that can quickly view or scroll more than 100,000 messages with inline images. It supports multi-tabs, high speed incremental full text search, and adding comments or images to messages.
Group, voice, and video chats: IP Messenger supports group chats with up to 100 users. You can also make voice or video calls with other users using WebRTC technology.
Multiplatform support: IP Messenger is available for Windows, MacOS X, Linux, Android, Java, KDE, and other platforms. You can communicate with users on different devices using the same protocol.
IP Messenger security
IP Messenger is designed to provide secure communication over LAN without relying on any third-party servers or cloud services. It uses end-to-end encryption (E2EE) to ensure that only the intended recipients can read your messages. It also does not store any metadata or IP addresses on its servers. Here are some of the security measures that IP Messenger implements:
E2EE with RSA2048bit + AES256bit + SHA-256: IP Messenger uses RSA2048bit public key encryption to exchange AES256bit symmetric keys between users. It then uses AES256bit to encrypt the message content and SHA-256 to generate the message digest. It also uses PKCS#1-v1_5 to sign or verify the messages with digital signatures.
Perfect forward secrecy (PFS): IP Messenger generates a new AES256bit key for each message, and deletes it after the message is sent or received. This prevents anyone from decrypting past messages even if they obtain the RSA private key or the AES key.
Message lock: IP Messenger allows you to lock your messages with a password or a fingerprint. This prevents anyone from reading your messages without your permission, even if they have access to your device or log file.
Message expiration: IP Messenger lets you set an expiration time for your messages, after which they will be automatically deleted from both the sender's and the receiver's devices and log files. This reduces the risk of data leakage or unauthorized access.
