Sharp Serialization Library is a Scripts software developed by Conversive. After our trial and test, the software is proved to be official, secure and free. Here is the official description for Sharp Serialization Library:

Edit By BS Editor: Use it for SOAP/Web Services communications where Hashtables cannot be passed otherwise, or saving to a file Readable by PHP.This C# Serialization Library is used to serialize objects to strings and deserialize objects from strings formatted using the same scheme as the PHP Serialize function.

Sharp Serialization Library can be used to pass complex objects over a SOAP Web Services connection which would otherwise not be supported through XML (SOAP) serialization, such as Hashtables.
