    PHPMailer

    PHPMailer

    The classic email sending library for PHP

    PHPMailer – A full-featured email creation and transfer class for PHP. Support for UTF-8 content and 8bit, base64, binary, and quoted-printable encodings. SMTP authentication with LOGIN, PLAIN, CRAM-MD5, and XOAUTH2 mechanisms over SMTPS and SMTP+STARTTLS transports. Validates email addresses automatically. Many PHP developers need to send email from their code. The only PHP function that supports this directly is mail(). However, it does not provide any assistance for making use of popular features such as encryption, authentication, HTML messages, and attachments. Formatting email correctly is surprisingly difficult. There are myriad overlapping (and conflicting) standards, requiring tight adherence to horribly complicated formatting and encoding rules – the vast majority of code that you'll find online that uses the mail() function directly is just plain wrong, if not unsafe!

    Ultroid

    Ultroid

    Telegram UserBot, Built in Python Using Telethon lib

    Ultroid, a pluggable telegram userbot, made in python using Telethon! Ultroid has been written from scratch, making it more stable and less crashes.

Error handling been done in the best way possible, such that the bot doesn't crash and stop all of a sudden. Ultroid has minimal amount of plugins (just the necessary ones) in the main repository, and all the other less-useful stuff in the addons repository. This facilitates quick deployments and lag-free use. Ultroid can install any plugin from the most of the other 'userbots' without any issue.

    IRremote Arduino Library

    IRremote Arduino Library

    Infrared remote library for Arduino, send and receive infrared signals

    This library enables you to send and receive using infra-red signals on an Arduino. You can use any pin for sending now like you are used to receiving. Simultaneous sending and receiving. See the SendAndReceive example. No more need to use 32-bit hex values in your code. Instead, a (8 bit) command value is provided for decoding (as well as a 16-bit address and a protocol number). Protocol values comply to protocol standards, i.e. NEC, Panasonic, Sony, Samsung, and JVC decode and send LSB first. Supports more protocols, since adding a protocol is quite easy now. Better documentation and more examples. Compatible with tone() library, see ReceiveDemo. Supports more platforms, since the new structure allows to easily add a new platform. Feedback LED also for sending. Ability to generate a non-PWM signal to just simulate an active low receiver signal for direct connection to existent receiving devices without using IR.

    Official Android SDK for Stream Chat

    Official Android SDK for Stream Chat

    Android Chat SDK ➜ Stream Chat API. UI component libraries for chat

    This is the official Android SDK for Stream Chat, a service for building chat and messaging applications. This library includes both a low-level chat SDK and a set of reusable UI components. Most users start with the UI components and fall back to the lower-level API when they want to customize things. We're proud to say that we're the first Android Chat SDK that supports Jetpack Compose! We released our Compose UI Components one day after the official Jetpack Compose 1.0 release and our team members have been working hard on it since then. Now it's mature and stable enough for us to officially recommend it for all new applications and all modern chat implementations. If you're looking for something highly customizable and extremely performant, check out our Compose SDK.

    base64 RFC1113 Vanilla ANSI-C Code for a portable stand-alone file encode/decode utility. In 2001, I asked people to 'Help me break it!' Since then, 10+years later, the code remains unbroken and is in wide production use world-wide. It has been ported to all major architectures and been used as a template for ports to different computer and human languages. This is very mature and stable code. Although this comes from a project that was constrained by export controls and is used in secure systems, it is not security code per-se. I have therefore altered the 'Export Controls' category.
