CryptSharp provides a number of password crypt algorithms: BCrypt, MD5 (and Apache's htpasswd variant), PHPass (WordPress, phpBB, Drupal), SHA256, SHA512, and Traditional and Extended DES. It also includes Blowfish, SCrypt, and PBKDF2 for any HMAC (.NET's built-in PBKDF2 implementation supports only SHA-1). If you are looking to store passwords, odds are CryptSharp will have the algorithm you want.
NetIRC2 is an easy-to-use .NET IRC client library. It supports all major features relevant to making a chat client or bot. It has full support for synchronization contexts. You can use it from a Windows Forms or WPF GUI thread and chat events will be automatically dispatched, allowing you to completely ignore multithreading. It uses byte arrays internally, so mixed encodings can be handled. The IrcClient class can even be used as a component in the Forms Designer. Because it speeds up connect times with some IRC servers, an Ident server is included as well.
The ABOUT tool and ABOUT files provide a simple way to document the provenance (origin and license) and other important or interesting information about third-party software components that you use in your project. The tool is a command line based utility. The ABOUT tool helps automate OSS compliance that is needed throughout the software lifecycle.
JS Diff Viewer is a library that can find and view the difference between two text strings. It takes two text strings, uses the diff algorithm to find the differences between them, and returns a list of changes to patch the original string to become the final string. The patch list shows which characters are added or removed to change one string into the other. The difference between the text strings may be computed in three modes: by character, by word or by line. The object can also format the strings to view them as HTML, showing which characters are added and removed with special insertion and deleted styles. The example page works as a tool to interactively view the changes as the user changes the texts before and after the changes are applied.
