The following components are from around 2002-2003. They are free to use but are closed source.
MD5DLL Encryption component
The message digest algorithm was developed by Professor Ronald L. Rivest of MIT. 'The MD5 algorithm is intended for digital signature applications, where a large file must be "compressed" in a secure manner before being encrypted with a private (secret) key under a public-key cryptosystem such as RSA.' MD5 is a hash, i.e it is not reversible without a lot of effort. The component was written by W.Tracz.

RC4DLL Encryption component
RC4 is a variable key-size cipher (the text can be decrypted if you have the key). It was designed by Rivest for RSA. This is an implementation of how the cipher is believed to work, and not the actual encryption software, which is available from RSA. More information can be found here. The component was written by W.Tracz.
RSADLL Encryption component
The RSA algorithm was invented in 1978 by Ron Rivest, Adi Shamir, and Leonard Adleman. It is a public and private key cipher. The component includes an example of a public and private key, a component for creating these keys is included in the download. More information on RSA can be found here. The component was written by W.Tracz.
InteliSource HTTP source component
InteliSource is a component with allows an application to directly connect to a web server to request a web page. The component returns the source of the file as a string, which can be parsed at will. Secondary routines, such as a function to remove all HTML make this component a must-have for any ASP programmer, COM enabled system or application. The component was written by James Linden .
NETDLL Network utilities
NETDLL is suite of networking tools built into one ASP component. Included is a ping function, an IP to hostname lookup, a hostname to IP lookup and a function for retrieving the serving computer's IP.
WhoisDLL
WhoisDLL is a Whois COM object that makes querying domain names a lot easier. The whois server is automagically found (whois servers aren't hard coded in) by WhoisDLL, and the lookup is then done using this. The server it uses is then available as a property, the whois lookup is performed using one simple method.
DataProducer - data tag parser for html templates
Like all the other Dataproducer classes on the website, the idea behind it is to separate the presentation layer from the data layer (a templating system), by simply creating a html file with custom data tags. Unlike XML/XSLT, which may not be appropriate for a specific project, you simply call one of 3 methods to replace the tags with data, including support for looping data such as. This has of course been superceded by superior templating engines now, or other technologies.
