katana.units.crypto.rot47 — ROT47 Cipher¶
ROT47 decoder
The gist of this code is ripped from https://rot47.net/_py/rot47.txt.
This unit inherits from the
katana.unit.NotEnglishAndPrintableUnit class, as we can expect
the data to still be printable characters (letters, numbers and punctuation)
but not readable English. It also inherits from the
katana.units.crypto.CryptoUnit class to ensure it is not a viable
URL or potentially useful file.

class
katana.units.crypto.rot47.Unit(manager: katana.manager.Manager, target: katana.target.Target) Bases:
katana.unit.NotEnglishAndPrintableUnit,katana.units.crypto.CryptoUnit-
BLOCKED_GROUPS= ['crypto'] These are tags for groups to not recurse into. Recursing into other crypto units would be silly.
-
GROUPS= ['crypto', 'rot47'] These are “tags” for a unit. Considering it is a Crypto unit, “crypto” is included, and the name of the unit, “rot47”.
-
PRIORITY= 45 Priority works with 0 being the highest priority, and 100 being the lowest priority. 50 is the default priorty. This unit has a slightly higher priority.
-
RECURSE_SELF= False Do not recurse into self

do_rot47(s) Shamelessly stolen from https://rot47.net/_py/rot47.txt
