### Tool 127: Cypher/decypher a file using a xor

### Description:

      This tool permits to cypher and decypher a file. This algorithm is not
      very strong, and can be defeated using a known text attack.
      It uses the --password parameter to generate a pseudo-random string.
      Then, a XOR is done between the string and the file's content.
      Due to XOR properties, this tool can also decrypt.

### Usage:

netwox 127 -p password -i file -o file

### Parameters:

parameter | description | example
`-p|--password password` | password |
`-i|--src-file file` | source filename | srcfile.txt
`-o|--dst-file file` | destination filename | dstfile.txt

### Examples:

netwox 127 -p "" -i "srcfile.txt" -o "dstfile.txt"
netwox 127 --password "" --src-file "srcfile.txt" --dst-file "dstfile.txt"
