detect encryption method

Is there a tool that automatically looks if popular encryption methods were used on a text if I have the decrypted as well as encrypted text?
If you don't know a tool could you please at least advise me to a forum where I could get some help with this.

I did have the intention to write a programm though it wasn't loadhax.exe.
I just need to find out the encryption method in order to use it for the programm I was gonna write.
But nvm, I get the point. This board is just for either questions that give the PROgrammers here the chance to show how friggin elite they are or for threads that mutate into the typical 'language x is superior to all others' threads
