I searched with google if anyone had similar problem, but I found

I suspect something in my code being wrong, but I cannot understand what.
You need to make two call to EVP_EncryptInit_ex etc if you want a non-default
key length. Check out the examples in the manual page:

Really sorry. I did try calling twice EVP_EncryptInit_ex, but I set also
const EVP_CIPHER * parameter.
Now it works, thank you all my life.
