Brute force
I have a texte crypted with the "code Vigenaire" and I have to youse the brute force method to decrypt it. I don't really know how to code that. Can someone help me with this please?
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
