We must presume that you do know how that encryption operates.
There seems to be language statistical heuristics. See descritions in:

"brute force" usually means systematic search through all possible combinations.
The linked site mentions the use of english dictionary to check whether a decrypted "result" looks like english.

it is very useful but my text isn't in english but in french so it isn't possible to decrypt it with the link...
I shoumd find how to make a program that can decrytpt a message witch is crepted with a key that I doesn't know. I don't know how the write the program in fact.

The point of the link is that they describe
* How they guess the length of the key
* How they guess the key once they know its lenght
* Obviously, if the message is known to be in french, then one should use french dictionary and grammatic rules
