It's given that a string, encoded in
hex format, is obtained by XOR encryption of a plain text and a key. The key is unknown (not even the length). What are the steps that I should follow to get the plain text? Since I am new to this, I am unaware of the tools to be used.
Example: Crack the following hex encoded string, obtained by XOR cipher:
PS: I know that by applying XOR on the cipher text with the key will give me back the plain text. How should I proceed, if I don't know the key?
