ROT13(シーザー暗号)の解き方 備忘録

More than 1 year has passed since last update.

シーザー暗号の解き方に関する備忘録です。

解き方

Pythonに元々実装であるため、

$ python
>>> import codecs
>>> codecs.decode('Uryyb, Jbeyq!','rot13')
'Hello, World!'
>>> 

これだけで解けちゃいます。

対話型シェルの終わり方

qでもquitでも終わらず、(エディタの名残かな?)
少し困ったので書いておきます。

exit()

これだけでいけたんですね。
