NAME

rot13 — encrypt or decrypt caesar ciphers

SYNOPSIS

rot13 [-p|--printable] [-r|--rotate number] [--debug] [--help|-?] [--version] [--] [string ...] [filename ...]

DESCRIPTION

The rot13 utility encrypts or decrypts caesar ciphers using a rotation of 13 characters. By default, rot13 reads from the standard input and writes to the standard output. If an optional parameter corresponding to a valid filename is given, rot13 will process this file instead. If the optional parameter is not a filename, rot13 will rotate this string.

OPTIONS

Options	Use
-p|--printable	Rotate all printable ASCII characters instead of just the alphabetical ones
-r|--rotate number	Rotate ''number'' characters instead of 13
--debug	Enable debug mode
--help|-?	Print usage and a short help message and exit
--version	Print version and exit
--	Options processing terminator

ENVIRONMENT

The ROT13_DEBUG environment variable can also be set to any value to enable debug mode.

EXIT STATUS

The rot13 utility exits 0 on success, and >0 if an error occurs.

SEE ALSO

STANDARDS

The rot13 utility is a standard UNIX command, though not a POSIX one.

It tries to follow the PEP 8 style guide for Python code.

PORTABILITY

Tested OK under Windows.

HISTORY

Rotated postings to USENET and some of the databases used by the fortune(6) program are rotated by 13 characters.

This re-implementation was made for the PNU project.

The ability to process optional strings or filenames, as well as choosing a different rotation or character set, has been added in this re-implementation.

LICENSE

This utility is available under the 3-clause BSD license.

CAVEATS

Unicode characters are left unchanged.

SECURITY CONSIDERATIONS

This command's only purpose is to obfuscate a text, rather than seriously intending to protect it. This last purpose has been deprecated about 2000 years ago!
