This class can be used to encode e-mail addresses to make it more difficult to grab by e-mail harvesting robots. It can take an e-mail address and replace some of its characters to make it difficult to recognize by robots by replacing @ and . characters by respective images. The class can also do the opposite, i.e. replace the images and decode the e-mail address by @ and . characters respectively. Since v1.1 checks for valid email address and also encode the username part. Since v1.2 it replaces the @ and . for images and also checks DNS records to Internet host name of the given email

This class can be used to check if a given IP address could be a proxy server responding in ports usually used by proxies. It can generate a log with IP addresses and the information whether it can be a proxy. Rex v1.1 features: - Proxy port scan can be disabled (in some cases, it blocks users that have port 80 open in their router configuration) - Added checkspamcop() that checks if a user IP is registered as spammer on Spamcop.net (can be enabled/diabled) - Function filtraxss() renamed to checkxss() because it really checks the presence of malicious xss doesn't filter anything - Function checkxss() only accepts arrays - Added filterxss() that removes or disables tags - Added checksize_db_data() that can be used to check for data size before inserting in database - Added filtersql() that escapes special characters in a string for use in a SQL statement

NXLicenser uses LocalKeys to license scripts. On the scripts first run it callsback home to get the encrypted data for the localkey then writes the localkey. If your script is not licensed, suspended, or expires it will not work. But if it is licensed and every thing is fine it will work. After that the script callsback once every 7 days to fetch a new localkey to update the license data. By using this method the script will not callback on every page load making it run faster while still being protected.
