Improve this answer. As you wrote that the general method to recover a short key given a ciphertext and a knowledge that the plaintext has some discernible characteristic like: is English text is brute force.

If the encryption program use a competent key stretching , do you know a good software that can brute force this password or key? I really looked in the internet for days but i could not find a good one except for Cryptool which is very slow.

In particular, they need to know the exact details of the ciphertext format and stretching, and what they can expect for the plaintext at least if short. Chances that something ready made exists for a proper thus stretching encryption program written independently are practically zero.

Chances that something freely or commercially available works to break free or commercial product named xxxx and is not found by googling password cracking xxxx are low. So If the chances to find this rc4 password cracking tool are very low even by using google.

So how do you think i can bruteforce this rc4 english password? It is to computer what driving is to car: if you can't, you'll need to convince someone who can to perform it for you. Whoever finds this RC4 password will first need to determine exactly how the password and plaintext are combined into ciphertext: "RC4 encryption" is not precise enough.

If there is no stretching and the plaintext is English with more than about 20 characters in the usual ASCII character set, the rest is easy, and in fact a gentle introduction to programming. Add a comment. Sign up or log in Sign up using Google. Sign up using Facebook.
