Forgot to blog: on Windows, use Certutil to Get File Hashes

Posted by jpluimers on 2023/10/19

I have had these two batch files on my system forever:

  • sha1.bat:
    :: https://superuser.com/questions/245775/is-there-a-built-in-checksum-utility-on-windows-7
    :: https://www.mcbsys.com/blog/2017/03/use-certutil-to-get-file-hash/
    :: Windows 7 has case sensitive Hash algorithms: MD2 MD4 MD5 SHA1 SHA256 SHA384 SHA512
    certUtil -hashfile %* SHA1
  • sha256.bat:
    :: https://superuser.com/questions/245775/is-there-a-built-in-checksum-utility-on-windows-7
    :: https://www.mcbsys.com/blog/2017/03/use-certutil-to-get-file-hash/
    :: Windows 7 has case sensitive Hash algorithms: MD2 MD4 MD5 SHA1 SHA256 SHA384 SHA512
    certUtil -hashfile %* SHA256

But I forgot to blog about [Wayback/Archive] Use Certutil to Get File Hash | MCB Systems mentioning:

on Windows 7, the hash algorithms are case-sensitive. Be sure to type, for example, “MD5”, not “md5”. On Windows 8.1 and 10, case doesn’t matter

I did mention the first link in “error: invalid object 100644” “git svn”, though only in a by-line. So thanks [Wayback/Archive] user64996 for asking and:

Chrome (likely also Firefox/Edge/Safari): no non-global way to workaround Bookmarklets failing on GitHub raw code with “Blocked script execution…”

Posted by jpluimers on 2023/10/18

Last year, I answered [Wayback/Archive] javascript – Bookmarklet to append a string to a URL – Stack Overflow (asked by [Wayback/Archive] Karlo Guidoni Martins, thanks!).

It is about not being able to run bookmarklets on pages hosted by for instance:

  • gist.githubusercontent.com
  • raw.githubusercontent.com

GitHub is an exception, as RAW files from these services do work fine:

At first sight, when running a Bookmarklet on those RAW GitHub served pages, you do not see an error: it just looks like the Bookmarklet does not work at all. The last part is right, but in the Chrome console you can actually see the error.

That error lead me to my answer:

GitHub – kellyjonbrazil/jc: CLI tool and python library that converts the output of popular command-line tools and file-types to JSON or Dictionaries. This allows piping of output to tools like jq and simplifying automation scripts.

Posted by jpluimers on 2023/10/17

I already knew about jq and jo (output: the echo for JSON), but not yet about jc for JSON.

Like jq is for querying (the sed for JSON), jc tries to be the universal parser of common command-line tools into JSON:

[Wayback/Archive] kellyjonbrazil/jc: CLI tool and python library that converts the output of popular command-line tools and file-types to JSON or Dictionaries. This allows piping of output to tools like jq and simplifying automation scripts.

Via [Wayback/ArchiveKris on Twitter: ““Jc” verwandelt den Output von üblichen Linux Kommandozeilen Tools in JSON. “Jc” kann auch als Import in Python Programmen verwendet werden und mit subprocess kombiniert werden. Danke, ⁦@janwalzer⁩ und ⁦@the_mutax⁩ für den Tip. “

A few weeks later though, Kris discovered that command-line tools aren’t that portable in their output format: [Wayback/Archive] Kris on Twitter: “As much as I love the idea of @kellyjonbrazil’s jc, this is not a winnable game. sigh Probably still better than a self-cooked parser, but the slightest bit of extra makes it catch fire in multiple possible ways …”

When reg.exe gives you “ERROR: Invalid key name.”

Posted by jpluimers on 2023/10/16

Be careful phrasing reg.exe commands.

Sometimes it gives you the error ERROR: Invalid key name.

The reason is that the reg.exe is really sensitive on the order of the command-line: the first argument must be a full key, optionally prepended by a computername.

Any other optional command-line option (like /f to force execution without asking) needs to go after that.

Ookla speedtest CLI for Windows has some undocumented arguments to accept license and GDPR

Posted by jpluimers on 2023/10/11

I had speedtest-cli running on MacOS and various Linux machines, but not yet on Windows (see for instance my post Ubuntu: Fixing the myserious “Failed to stop apt-daily.timer: Connection timed out”).

[Wayback/Archive] Install and Test Internet Speed with Speedtest CLI Command Line – NEXTOFWINDOWS.COM reminded me there is a Speedtest CLI for Windows download at at [Wayback/Archive] Speedtest CLI: Internet speed test for the command line, but I am a an automation/scripting/devops person, so luckily there are also [Wayback/Archive] Chocolatey Software | Speedtest by Ookla (don’t get [Wayback/Archive] Ookla.Speedtest download, as that is the GUI version).

Both the Chocolatey and winget packages are named the same, so that is quite confusing. This is how I have set them apart:

Getting the Chocolatey shimgen generated shim target

Posted by jpluimers on 2023/10/10

For tomorrow’s post Ookla speedtest CLI for Windows has some undocumented arguments to accept license and GDPR I neede the full path to the speedtest.exe which I had installed using Chocolatey.

I know chocolatey uses a shim that redirects to the actual executable, so a simple where speedtest.exe would not cut it.

My guess would be that the generated shim allowed to either get the target pathname out, or have the target pathname encoded in it.

Luckily the first applies: a few of the shim command-line parameters are in [Wayback/Archive] Chocolatey Software Docs | Executable shimming (like symlinks but better):

You pass these arguments to an executable that is a shim (e.g. executables in the bin directory of your Chocolatey install, not choco.exe):

  • --shimgen-help – shows this help menu and exits without running the target
  • --shimgen-log – logging is shown on command line
  • --shimgen-waitforexit – explicitly tell the shim to wait for target to exit – useful when something is calling a gui and wanting to block – command line programs explicitly have waitforexit already set.
  • --shimgen-exit – explicitly tell the shim to exit immediately.
  • --shimgen-gui – explicitly behave as if the target is a GUI application. This is helpful in situations where the package did not have a proper .gui file.
  • --shimgen-usetargetworkingdirectory – set the working directory to the target path. Useful when programs need to be running from where they are located (usually indicates programs that have issues being run globally).
  • --shimgen-noop – Do not actually call the target. Useful to see what would happen if you ran the command.

But the below dumps show more more (using [Wayback/Archive] Strings – Windows Sysinternals | Microsoft Docs, [Wayback/Archive] clip | Microsoft Docs and post-processing in [Wayback/Archive] Notepad++).

Back to the second solution,

strings C:\ProgramData\chocolatey\bin\speedtest.exe | findstr speedtest.exe

showed

speedtest.exe
..\\lib\speedtest\tools\speedtest.exe
Cannot find file at '..\\lib\speedtest\tools\speedtest.exe' (
speedtest.exe
speedtest.exe

And towards the first,

strings C:\ProgramData\chocolatey\bin\speedtest.exe | clip

resulted in this fragment:

Bookmarklet to navigate from a page to the most recent saved WayBack machine entry

Posted by jpluimers on 2023/10/04

A while ago, while writing last weeks post XPath based bookmarklets for Archive.is: more JavaScript fiddling!, I needed the most recent WayBack Machine archival of

https://developer.mozilla.org/en-US/docs/Web/XPath/Introduction_to_using_XPath_in_JavaScript

I vaguely remembered replacing the normal timestamp with a 3 and 13 zeros, so I tried this

https://web.archive.org/web/30000000000000/https://developer.mozilla.org/en-US/docs/Web/XPath/Introduction_to_using_XPath_in_JavaScript

And indeed, it did a HTTP 302 redirect to

https://web.archive.org/web/20220312161117/https://developer.mozilla.org/en-US/docs/Web/XPath/Introduction_to_using_XPath_in_JavaScript

So I quickly made this bookmarklet:

javascript:location.href='https://web.archive.org/web/30000000000000/'+document.location.href;

Then I created another one for getting the screenshot:

javascript:location=location.href.replace(/^https:\/\/web\.archive\.org\/save\/http/,'https://web.archive.org/web/30000000000000/http://web.archive.org/screenshot/http')

That works for screenshots archived with a Wayback Machine account, as these are related because of the inserted http://web.archive.org/screenshot/ fragment:

Since the Wayback Machine always looks for the closest savet timestamp, it does not matter the timestamps in these archived pages have a slight mismatch.

Memory lane

20231006: I edited this section referring two prior blog posts instead of one because of [Wayback/Archive] pbeccard: “@wiert @oliof You can also use…” – Mastodon (clearly showing that Mastodon like any social media platform does mangle backtick quoted code):

@wiert @oliof You can also use `javascript:location.href=’web.archive.org/web/*/’+docume to get the overview. I find this quite useful since I often want an older version of a page.

And later in the reply chain:

[Wayback/Archive] pbeccard: “@wiert @oliof Ah, I thought b…” – Mastodon

@wiert @oliof Ah, I thought by now that maybe Markdown is supported. I pulled the bookmarklet out of my bookmarklet bookmark folder. Here is a copy: https://gist.github.com/corppneq/d61e3…

[Wayback/Archive] Gist: Bookmarklets

I also found back two blog posts:

  1. Need to write a proper bookmarklet for the wayback archive (: mentioning many useful Wayback Machine JavaScript Bookmarklets from my gist [Wayback/Archive] Ideas/inspiration for writing a proper WayBack archive.org bookmarklet including this one:

    [Wayback/Archive] http://www.gyford.com/misc/wayback.html

      • WayBack:

        javascript:location.href='http://web.archive.org/web/*/'+document.location.href;
        

    I also archived this referred page: [Wayback/Archive] Bookmarklets.com – What’s New.

  2. JavaScript bookmarklet to replace part of the WayBack machine URL with a bookmarklet replacing

    JavaScript bookmarklet to replace part of the WayBack machine URL:

    A bookmarklet that goes to the latest rendered saved version (sometimes saved versions have not been rendered yet, so you get the latest available render):

    javascript:location=location.href.replace(/^https:\/\/web\.archive\.org\/save\/http/,'https://web.archive.org/web/30000000000000/http')

    The WayBack Machine uses a 14-position ID and tries to find the render that is the most close by. This is the format of the ID:

    yyyymmddhhmmss

    This is granular enough, as the WayBack machine only allows new saves that are usually 30+ minutes apart.

    (Note that period by now seems to be increased from 30+ minutes to 45+ minutes)

It also found back this post having the same huge number: 0.30000000000000004.com. How cool is WordPress search (:

The JavaScript bookmarklets that saved me a lot of time documenting the Embarcadero docwiki outage

Posted by jpluimers on 2023/09/28

Winter 2022, the Embarcadero docwiki (their most active site which contains all documentation for all their products) was down. Twice. First for a week, then parts of it for almost a week, then only parts of the Alexandria got up in a stable way.

Back then I published The Delphi documentation site docwiki.embarcadero.com has been down/up oscillating for 4 days is now down for almost a day.. The product and library documentation for the most recent version got back up in a week, but the Code Examples and older product versions took much longers.

Usually once learns way more about a system when it is failing then when it is working. That was the case this system as well.

Documenting the failing system took considerable time, but would have taken way more if not for these two JavaScript browser bookmarklets:

Javascript – Copy string to clipboard as text/html – Stack Overflow

Posted by jpluimers on 2023/09/27

For my link archive is the below answer that should help me a lot with unfinished bits from Some JavaScript bookmarklets for WordPress published pages centered around navigation and IDs.

Goal of that post was to have some grounding and eventually find a means to build an HTML page in a new tab using a bookmarklet that I then later could post to my blog.

Assembling to HTML and putting it on the clipboard might be a lot easier and better fitting in my workflow.

So, via [Wayback/Archivejavascript copy html to clipboard – Google Search, for my link archive: [Wayback/Archive] Javascript – Copy string to clipboard as text/html – Stack Overflow (thanks [Wayback/Archive] Loilo for answering and [Wayback/Archive] kofifus for asking):

Below is a function that will do exactly that. I tested it with your required browsers, it works in all of them. However, IE 11 will ask for confirmation on that action.

Explanation how this works can be found below, you may interactively test the function out in this jsFiddle.
