Don't fear to edit my posts: even if I have more reputation than you, I do make mistakes.

I'm now also a Moderator Pro Tempore (= until the first elections) at Cryptography Stack Exchange: feel free to come around and ask some cryptography questions.


My personal name is spoken as /ˈpawlo/ (IPA), in English this would be written similar to Powlo, I think (i.e. the vowels are ow and o), with an accent on the before-last syllable (which is the first in this case). It's the Esperanto form of my given name.

The photo shows my shadow, taken at night. My camera sometimes seems to forget all the other frequencies and only stores the green ones.

My current main private programming project is the game of fencing, an online abstract turn based strategy game. Implemented as a Java applet, using git as a version control system.

@D.W. Do you know that there is a close-link where you can formally mark a question as a duplicate? (Just below the tag line.)

comment Is AES really used for Top Secret stuff?
@WilliamHird Sorry, I must have missed you. I normally only add a "Welcome" when I have something else to say, too, and maybe your start was perfect? Or back then I was not in the mood of welcoming people, since everyone was new (me included)? I don't know, it was almost two years ago. (I see I edited your first question, I should had added a comment, too. But I wasn't even a moderator then.)

@schrobe Welcome to Cryptography Stack Exchange. If you think poncho's answer answered your question fully, please accept it (klick the checkmark icon beside it), so others can see that this question is "solved".

comment Is this a sensible cryptographic protocol intending to reduce the impact of compromised security?
@RickyDemer They read over a long time, and the data might need to be analyzed in a short time frame.

comment Generate fixed length cipher text from arbitrary length plaintext
Welcome to Cryptography Stack Exchange. Do you want to be able to decrypt this again? Then it is impossible in general to have a shorter ciphertext than the plaintext. Otherwise this is not called encryption but a "hash" ... it is possible to build a hash function from AES, but not trivial to do so in a secure way.

The latin plural is "statūs", with a long u, not stati.
