testing an encryption method?

Hi,
I am trying to build a sort of encryption for my website without having to use ssl.
What I am wondering is if there are software programs or other methods to retreive an encrypted password.

Should anyone know (or use) such software, I was wondering if it is possible to test my encryption method by trying to retreive the original password.

Here is my situation:sending password from database to client

//on the server side
1) password=????//have to guess this one
//over the internet
1) created keys
key1=41;
key2=22;
key3=58;
2) encrypted password
229302267891259202273

The front end is an swf file,(where the decryption-script takes

So basically is it possible to put these variables into a program and see if it can decrypt it?

thanks
Patrick

you need a symmetric algorithm which can be reversed by possessing the keys you mentioned.
