@Bálint Let's solve it? :3

@zʏᴀʙiɴ101 Is 4 ice?

@Bálint 3 < 4

The length of the word ICE is 3, which is not 4.

@zʏᴀʙiɴ101 Ohh, hm

Hint: one of the items is crosswordese.

@zʏᴀʙiɴ101 The only 3 letter measurement for a cloth is the tex

I'm still thinking

@zʏᴀʙiɴ101 Is the first sybarite?

But then tex is invalid

@Bálint Did you mean the second? >_>

@Bálint Don't worry, the letter T in TEX will be overriden.

@zʏᴀʙiɴ101 Yeah

I don't have any more ideas

12:31 PM

Don't worry, I posted about it in the Nth Monitor, so that I can try to get a few more SE users to try the crossword.

Also we have @Jo7.

@EʀɪᴋᴛʜᴇGᴏʟғᴇʀ Let's decrypt that message :3

@zʏᴀʙiɴ101 (to Puzzling.SE user) This is not anything, I generated it in a Hex editor.

:(

...6..K.`L......@....L.~T...z.....=5....m....Q...ZZ...?^<...@.h...`..k.Q..T.m‌.P This is the real thing.

Play with RSA encryption?

My public key: schas002.github.io/pubkey

2:59 PM

In fact, this was the message: Ꮐ㚮䱠쿾Ǭﻈ쭀߬䲿线ﱔ쀏喙뼅씆㔽샬冯냀媼앚ề帿긼쯋쭀왨쪄豠殰儑؛ꡔ셭 (still not anything)

Play with RSA encryption? :3

@zʏᴀnope, it would take a long long long long time

Don't worry, creating an RSA pub/priv key pair won't take long.

Yeah, but puzzling someone about the priv will take long. (Pre-cautions: privs must be fake, and they are the topic of the puzzle)

Will take a very long explanation.

I mean, playing with RSA encryption in here, in the Sandbox.

3:05 PM

Yeah, that's what I got, and the Sandbox is the correct place until Puzzling.SE has any support for such rooms. Although the long explanation can't fit in a message, and there is the possibility it will be fatally cut.

Generating an RSA priv key with OpenSSL with default settings, 2048 bit long modulus, e equalling 65 537 (#1 0001) took 3.748 secs on my machine.

Anyways, I've got you a site. I'm on Windows now.

travistidwell.com/jsencrypt/demo

@EʀɪᴋᴛʜᴇGᴏʟғᴇʀ fourmilab.ch/javascrypt

@EʀɪᴋᴛʜᴇGᴏʟғᴇʀ Do you have Git?

No, but I can make one right now (a public one on GitHub)

I'm on Windows, but I have cygwin installed.

I mean, do you have Git installed on your machine?

3:08 PM

No, I don't think I can install Git on Windows.

@EʀɪᴋᴛʜᴇGᴏʟғᴇʀ You can.

git-for-windows.github.io

It has the Git shell, which is a Bash emulator.

Meh, I have a more "official" link: https://git-scm.com/download/win

It's instant, i.e. it downloads instantly.

It also has OpenSSL and ssh, intended to be used by Git, but accessible to Bash.

And Git.

@EʀɪᴋᴛʜᴇGᴏʟғᴇʀ A download manager?! O_O

3:12 PM

Download Complete!

Alright, while your Git for Windows is installing, let's play with JavaScrypt.

@zʏᴀI use DownThemAll!, although the main point is "putting it on my PC now"

I use WinWget as my "download manager", however it is using wget in the background.

So basically, a front end of wget.

But I use the Firefox download manager for downloading most files.

Installing...

Alright, play with JavaScrypt? :3

3:14 PM

DownThemAll! is faster

Nah, it installed.

Alright, Git Bash is open!!!

First, set up Git to know who are you.

(It's not relevant to RSA encryption, but Git must know who are you to commit and push to GitHub.)

(The Git email must match with your GitHub email for the latter to recognize you.)

@Eʀɪᴋ Done?

@zʏᴀʙiɴ101 Not yet, but I cannot seem to find any command to login.

git config --global user.name $YOUR_NAME_HERE

Where $YOUR_NAME_HERE is your name, in "quotes".

@Eʀɪᴋ Done?

Ran this command: git config --global user.name erikkonstas

Although the command isn't listed in git --help

@EʀɪᴋᴛʜᴇGᴏʟғᴇʀ It is the command git config, with help available from git help config.

Alright, now git config --global user.email $YOUR_EMAIL_HERE, where $YOUR_EMAIL_HERE is your GitHub email, in quotes.

3:22 PM

Ran this command: git config --global user.email {{ erikkonstas.email }}, where {{ erikkonstas.email }} is my email, but it is hidden here.

Alright.

Main commands:

To create/open a repository: git init to make the current folder a repo, git init folder to create a repo in directory folder, git clone url to clone a repo from url.

The last command is often used like git clone https://github.com/user/repo to clone repos from GitHub.

To check the repo: git status for the current stage status, git log for the commit log.

Yeah, I know those.

To commit: git add to add items to the stage, then git commit to commit those.

@EʀɪᴋᴛʜᴇGᴏʟғᴇʀ You know even the push/pull and branch commands?

And even tag commands?

Yeah, commit "applies", push "uploads", pull "downloads", branch "copies".

Alright then, let's play with RSA encryption :D

My public key is here: schas002.github.io/pubkey

3:27 PM

Which private key did you use then?

(don't post here: it's huuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuge!)

@EʀɪᴋᴛʜᴇGᴏʟғᴇʀ The one on my computer in the C:\Users\zyabin101\.ssh folder, which I won't post here. ;)

Hmm... how can I decrypt then?

Generate a pub/priv key pair with ssh-keygen -t rsa.

@EʀɪᴋᴛʜᴇGᴏʟғᴇʀ Only I can decrypt the messages encrypted with my public key, because I don't share my private key. ;)

Post your public key somewhere.

AAAAB3NzaC1yc2EAAAADAQABAAABAQDRZRCJpVK/GBk+yGCgdfEEnyDpBxH1bhPekTWzuuOq+cJ9ozT‌QObD7+b9+UsnJWDnFV1H2s2GRFI5rbWwuPiHg2ZZoGkRyL2b2mUcm7sqcb4dtuE6A1r947NYuc/gHYgyC‌FdZEJC3RvF8x39wJoIvWhG2HPWsdm4YjlDV9OVwAjEzWFFyuJsW+CR4lbnV6Rt3IwJ9DAKfRkuIHYLkhh‌QD/O3clpBB0MFpSOTX9cIKp5x2+/yHKngQc+bfuCPKwrKh5Q3qEIXmiIdsOdH+Cx+Kyypuj61D8KbBjKg‌xSuCjUmLvqwonfFcYCcgSYJqJB6pBDXy9tuPa9iDhs93g3QUar

This is my public key.

Alright then, now convert it to the OpenSSL format with openssl rsa -in <private key file> -pubout.

@Eʀɪᴋ Done?

3:32 PM

Waiting...

Waiting

Waiting...

Waiting

Waiting :)

Adding entropy...

O_O Why are you generating a new pub/priv key pair again?

@zʏᴀʙiɴ101 No, converting to OpenSSL! Although I'm still waiting, and I'm typing to kill time!!!

Ah k :)

3:39 PM

I just backspaced a whole hundreds*hundreds screen!

STILL WAITING!!!!!!!!!!!

You hate this, right?

:O

@EʀɪᴋᴛʜᴇGᴏʟғᴇʀ I don't.

Generation of RSA keys is pretty fast.

After loading the data in the calculator, the statistics module, currently engaged, has 10 numbers memorised.

The average of 10 tries is 6.6206s.

The sum of 10 tries is 1min 6.206s.

I typed openssl rsa -in id_rsa -pubout

No!

openssl rsa -in id_rsa -pubout

You forgot the -in between rsa and id_rsa D:

Nope, I mis-typed it here.

The standard (average square) deviation of 10 tries is 2.1033896558755927390633148758507s.

@EʀɪᴋᴛʜᴇGᴏʟғᴇʀ :D

Nah, it does not work on me, it takes too long. I also have this problem with Ubuntu, so it's my PC, not the command :(:(:(:(:(
