<p>I need to write code in python language for comparing the text of document using fingerprint techniques. I do not know to take fingerprint of a document or to generate fingerprint of a document. I'm asking if anyone knows the method or has source code for generating fingerprints of documents which is stored in bits form.</p>

Nice to hear someone is using CruiseControl.NET. That is a nice tool. You can use a command line tool for obfuscation as RemoteSoft .NET Obfuscator and integrate a call to the tool in the build script. See example on how to execute a file below from CruiseControl.NET wiki.

```
<exec>
    <executable>make</executable>
    <baseDirectory>D:\dev\MyProject</baseDirectory>
    <buildArgs>all</buildArgs>
    <buildTimeoutSeconds>10</buildTimeoutSeconds>
    <successExitCodes>0,1,3,5</successExitCodes>
    <environment>
        <variable>
            <name>MyVar1</name>
            <value>Var1Value</value>
        </variable>
        <variable name="MyVar2" value="Var2Value"/>
        ...
    </environment>
</exec>
```
