Understanding Pidgin (software) and Its Capabilities

Pidgin is a free and open-source instant messaging client that allows you to connect to multiple chat networks at the same time.

It's a versatile tool that supports a wide range of protocols, including AOL Instant Messenger, Bonjour, Facebook Chat, Google Talk, and many more.

Pidgin can handle multiple conversations simultaneously, making it a great option for users who need to communicate with people on different networks.

With Pidgin, you can easily switch between conversations and even transfer files between contacts.

Pidgin is designed to be extended with plugins, allowing users to add support for various protocols and features.

Plugins can be written by third-party developers and are useful for adding significant features like end-to-end encryption with the "Off-the-Record Messaging" (OTR) plugin.

The TLS encryption system is also pluggable, making it easy to substitute different TLS libraries, with GnuTLS being the default and NSS also supported.

Pidgin supports voice and video chat, but only through the XMPP protocol, and calls can only be initiated through this protocol as of July 2015.

Pidgin's pluggability feature allows users to extend the program with plugins, which can be written by third-party developers. This means you can add support for new protocols, like Skype or Discord, without having to wait for the developers to implement it.

Plugins can also add significant features, such as the "Off-the-Record Messaging" (OTR) plugin, which provides end-to-end encryption. This is a big deal for users who value their online security.

The TLS encryption system is also pluggable, making it easy to substitute different TLS libraries. GnuTLS is the default, but NSS is also supported.

Some operating systems' ports, like OpenBSD's, choose to use OpenSSL or LibreSSL by default instead of GnuTLS or NSS. This flexibility is a testament to Pidgin's commitment to user choice and customization.

File transfer is a breeze with Pidgin. You can send files directly to another user over protocols like XMPP, making it a convenient way to share files with friends and colleagues.

Pidgin supports file transfers for many protocols, including the one I mentioned earlier, XMPP.

Pidgin has its own set of security concerns.

Encrypted anonymous conversations are supported using the OTR plugin, but it's not without its flaws. Both ends must have it installed for it to work, and it's unlikely that random people you want to converse with will have it.

The OTR protocol for Pidgin is available in most distributions under a package-name like pidgin-otr, or can be downloaded from http://www.cypherpunks.ca/otr/.

Using the OTR plugin is advisable, as it adds an encryption layer on top of the messaging networks protocol.

A huge issue with Pidgin in terms of security is that all of your accounts and passwords are stored in a plain text XML file ~/.purple/accounts.xml.

You can install Pidgin on Linux and Unix distributions using your operating system's standard package management tool. This is the recommended way to get Pidgin up and running.

Pre-built packages are available for Linux and Unix distributions, but they may be out of date. If this is the case, you can try building Pidgin from source.

If you're using a Linux or Unix distribution without pre-built packages, or if the pre-built package is outdated, building from source is a viable option.

Pidgin's plugins are a game-changer, allowing you to add a wide range of features to your instant messaging experience.

You can chat with friends on Discord using the purple-discord plugin, or connect with Facebook friends via purple-facebook.

Google Chat is also supported, thanks to the purple-googlechat plugin.

If you're a fan of microblogs, you can connect with GNU social or Twitter using the respective plugins.

Slack users can also join the party with the slack-libpurple plugin.

Telegram users can use the tdlib-purple plugin to connect.

End-to-end encryption is available through Off-the-Record Messaging (OTR), giving you an extra layer of security.

Want to add some math to your conversations? You can use LaTeX to write mathematical formulas.

Notifications can be customized to show "toaster" popups, Snarl notifications, or even light up your laptop's LEDs.

If you're listening to music, you can share what you're listening to with your contacts.

And if someone shares a video link, you can watch it directly in the conversation, without having to leave the chat window.

Pidgin has inspired a range of software projects based on its core library, libpurple.

Some notable examples include Adium and Proteus for macOS, although Proteus is no longer available.

Meebo, a web-based platform, was also built on libpurple, but is no longer accessible.

Other projects, such as Telepathy Haze and QuteCom, leveraged libpurple for functionality.

Here's a list of some notable software based on libpurple:

The libpurple codebase has been known for its bountiful security bugs, as observed by Wired in 2015. This has led to security vulnerabilities being discovered in popular OTR plugins using libpurple.

One notable criticism is the removal of the ability to manually resize the text input box of conversations in version 2.4 and later. This change led to a fork, Carrier (originally named Funpidgin).

The software also stores passwords in a plaintext file, making them readable by anyone or any program that can access the user's files.

The criticisms surrounding Pidgin are worth exploring. One major issue is the abundance of security bugs in the libpurple codebase, a fact observed by Wired in 2015.

This has led to security vulnerabilities being discovered in popular OTR plugins using libpurple, as seen in 2011. The consequences of these bugs can be severe, making users' data vulnerable to hacking.

Another concern is the removal of the ability to manually resize the text input box of conversations in version 2.4 and later. This change led to a fork, Carrier, also known as Funpidgin.

The way Pidgin stores passwords is also a point of contention. As of now, passwords are stored in a plaintext file, making them easily accessible to anyone with access to the user's files.

Here are some of the key criticisms of Pidgin's password storage:

Additionally, Pidgin lacks features like pausing or reattempting file transfers, making it less user-friendly in certain situations.

The original name of the software was GAIM, which stood for GTK+ AOL Instant Messenger. This name was a result of the project's initial development.

AOL exerted pressure on the development team, leading to a name change to simply gaim.

In 2007, the project team announced that gaim would be renamed to Pidgin, along with libgaim becoming libpurple and gaim-text becoming finch.

This name change was a result of talks between the project team and AOL, which aimed to resolve some of the legal issues.

The most recent version of Pidgin, version 2.5.7, resolved several connection issues.

To get the most recent version, you can add the Pidgin developers' repository to your sources.list.

The repository URL is: deb http://ppa.launchpad.net/pidgin-developers/ppa/ubuntu intrepid main

Note that unless the version is found in the official Ubuntu repositories, it's not supported and may not have undergone testing by Ubuntu maintainers.

If you need to use an older version of Pidgin, you can find binaries for it on the Pidgin package repository main page.
