Hello guys,

I'm temporarily occupied with programming in VB .Net and C#. I am not a pro in it and teach it myself. Nevertheless I want to share something with you that someone might want to use here.

It's a small library to generate captchas. You can embed it into existing projects with only 3 lines of code.

Suggestions and suggestions for improvements are welcome.


Link to the library : github. com/clusterzx/Captcha.NET

I don't understand the point of this as you can just read the "secret" from memory.

Agreed. This should be in php, client makes a request for the image, then sends the users guess back to server for validation

Not bashing op, still great job. With lots of obfuscation youll be as secure as youll need.

Sure but who does this at a captcha?
It would be easier to just write the code. This captcha can be used for normal software.
99,99% of the people dont know what memory in this case means. ^^

Thanks f411en :)

Anyway i appriciate your thoughts and completly agree with u both.

It could be used for asp.net sites aswell but yeah your point is valid for the example he provided.
