The Portable Document Format, or PDF, is a file format that can be used to present and exchange documents reliably across operating systems. def loop_user_query (k): """Raises EOFError when the user uses an EOT escape sequence (i.e. The reason for choosing RC4 is the simple implementation and speed. The major difference isthe replacement of Django specifics with examples for a Python client andserver implementation using the sslstandard library package. I need to implement RC4 in a script in Python and I found these two libraries: Pycryptodome -> https://pycryptodome.readthedocs.io/en/latest/src/cipher/arc4.html.
