Talk:Key space (cryptography)

Keyspace of ROT13
I would argue that the keyspace of ROT13 is rather of size 1 rather than empty. The argument I raise is that a vector space of dimension 0 has 1 element and not zero. So applying the same logic here, ROT13 has 1 possible key (furthermore, having no key makes decryption impossible). This is a very minor problem, so I'm not editing this, instead leaving it to the community to decide. Overall quality of the page is high, though. I know this might sound like I'm making this issue up, it might be true, in which case I beg your forgiveness and request the deletion of this section. 85.187.35.160 (talk) 23:03, 19 April 2011 (UTC)

Examples
One of the examples states "256 bits, resulting in a key space containing over 1.1579 × 1077 keys", would it not be clearer and more consistent with the article to state "256 bits, resulting in a key space of size 2^256"? --Flexdream (talk) 11:42, 14 September 2011 (UTC)
