Encrypt files using gpg and hmac-sha2-256 - batch-file

I wrote a script to encrypt a file using gpg, in a .bat script which takes in a filename passed from a powershell script. This is my .bat file (the important parts anyway):
gpg --batch --yes --passphrase "C:\users\me\Desktop\testkey.txt" --gen-key
"C:\users\me\Desktop\SetEncryptionSettings.txt"
gpg --batch --yes -r myuser--output %OutputParam% --encrypt %1
where SetEncryptionSettings.txt looks like this:
Key-Type: default
Subkey-Type: default
Name-Real: myuser
Name-Comment: nocomment
Name-Email: me#gmail.com
Expire-Date: 0
And this works. I can decrypt the file myself. However, I sent my file to someone else who appears to be using a different decryption algorithm...he says I should use hmac-sha2-256.
I understand the encryption options in a .bat file to provide these four options:
(1) RSA and RSA (default)
(2) DSA and Elgamal
(3) DSA (sign only)
(4) RSA (sign only)
which can be seen here, for example:
https://yanhan.github.io/posts/2017-09-27-how-to-use-gpg-to-encrypt-stuff.html
So I thought that my code was using RSA since that's the default...and that since there are no options here for hmac-sha2-256, I'm going to have to change everything now. Can I make this work using a similar setup to what I have now, without downloading any additional programs?

Any way to download latest GitHub release w/ a batch script?

So, I'm trying to download the latest release from GitHub using a Windows batch script. I can get a long list of URLs by running curl -s https://api.github.com/repos/ActualMandM/cemu_graphic_packs/releases/latest, but I can't figure out how to pass the "browser_download_url": "https://github.com/ActualMandM/cemu_graphic_packs/releases/download/Github828/graphicPacks828.zip" it outputs to curl. I've looked online, but everything I found was for PowerShell and most of them used wget.
If you really want to use batch for this, you'll have to search the output JSON for the value you're looking for and then process that string. If the JSON had appeared all on one line, you'd need to take a different approach, but you got lucky.
for /f "tokens=1,* delims=:" %%A in ('curl -ks https://api.github.com/repos/ActualMandM/cemu_graphic_packs/releases/latest ^| find "browser_download_url"') do (
curl -kOL %%B
)
I've added the -k flag because my computer requires it for some reason (so other peoples' might as well).
-O will set the name of the output file to the remote output file name
-L follows a redirect, which is required for downloading from Github.
The Github API url you're accessing returns JSON, so you're going to need a JSON parser.
I can highly recommend xidel. xidel can open and download urls, so you won't need curl or a batch-script.
To query the "browser_download_url"-attribute:
xidel.exe -s "https://api.github.com/repos/ActualMandM/cemu_graphic_packs/releases/latest" -e "$json//browser_download_url"
https://github.com/ActualMandM/cemu_graphic_packs/releases/download/Github874/graphicPacks874.zip
(or -e "$json/(assets)()/browser_download_url" in full)
To download 'graphicPacks874.zip' in the current dir:
xidel.exe ^
-s "https://api.github.com/repos/ActualMandM/cemu_graphic_packs/releases/latest" ^
-f "$json//browser_download_url" ^
--download "{substring-after($headers[starts-with(.,'Content-Disposition')],'filename=')}"
With r8389 or newer (because of this commit) you can just use --download ..

Optimal usage of codecov in a monorepo context with separate flags for each package

I was just wondering what’s the best way to configure codecov for a monorepo setting. For example, let’s say I have packages A and B under my monorepo. The way I’m currently using codecov is by using a github action codecov/codecov-action#v1, by using multiple uses statement in my GitHub workflow YAML file like the following:-
- uses: codecov/codecov-action#v1
with:
files: ./packages/A/coverage/lcov.info
flags: flag_a
name: A
- uses: codecov/codecov-action#v1
with:
files: ./packages/B/coverage/lcov.info
flags: flag_b
name: B
I know it's possible to use a comma-separated value to upload multiple files, but I have to set a separate flag for each package, and doing it that way doesn't seem to work.
Thank you.
If anyone wants to know my solution, heres what I came up with.
I ended up replacing the github action with my own bash script.
final code
#!/usr/bin/env bash
codecov_file="${GITHUB_WORKSPACE}/scripts/codecov.sh"
curl -s https://codecov.io/bash > $codecov_file
chmod +x $codecov_file
cd "${GITHUB_WORKSPACE}/packages";
for dir in */
do
package="${dir/\//}"
if [ -d "$package/coverage" ]
then
file="$PWD/$package/coverage/lcov.info"
flag="${package/-/_}"
$codecov_file -f $file -F $flag -v -t $CODECOV_TOKEN
fi
done
this is what the above bash script does
Downloading the bash uploader script from codecov
Moving to the packages directory where are the packages are located, and going through all the 1st level directories
Change the package name by removing extra slash
If the directory contains coverage directory only then enter into it, since only those packages have been tested.
Create a file and flag variable (removing hypen with underscore as codecov doesn't support hypen in flag name)
Executed the downloaded codecov script by passing the file and flag variable as argument

Create a vim script, function or macro and run in windows by command line

i created a script that converts a text file into utf8 encoding. I can run it in vim. The problem is that i need to run it by cmd in windows and i cant figure out how. Help me
Sorry for my english. Im from south america, i speak spanish.
Alternatives
Unless you really need special Vim capabilities, you're probably better off using non-interactive tools like sed, awk, or Perl / Python / Ruby / your favorite scripting language here. For simple character set conversion, look into the iconv tool in particular.
That said, you can use Vim non-interactively:
Silent Batch Mode
For very simple text processing (i.e. using Vim like an enhanced 'sed' or 'awk', maybe just benefitting from the enhanced regular expressions in a :substitute command), use Ex-mode.
REM Windows
call vim -N -u NONE -n -es -S "commands.ex" "filespec"
Note: silent batch mode (:help -s-ex) messes up the Windows console, so you may have to do a cls to clean up after the Vim run.
# Unix
vim -T dumb --noplugin -n -es -S "commands.ex" "filespec"
Attention: Vim will hang waiting for input if the "commands.ex" file doesn't exist; better check beforehand for its existence! Alternatively, Vim can read the commands from stdin. You can also fill a new buffer with text read from stdin, and read commands from stderr if you use the - argument.
Full Automation
For more advanced processing involving multiple windows, and real automation of Vim (where you might interact with the user or leave Vim running to let the user take over), use:
vim -N -u NONE -n -c "set nomore" -S "commands.vim" "filespec"
Here's a summary of the used arguments:
-T dumb Avoids errors in case the terminal detection goes wrong.
-N -u NONE Do not load vimrc and plugins, alternatively:
--noplugin Do not load plugins.
-n No swapfile.
-es Ex mode + silent batch mode -s-ex
Attention: Must be given in that order!
-S ... Source script.
-c 'set nomore' Suppress the more-prompt when the screen is filled
with messages or output to avoid blocking.

how to make a file non -editable through vi, >, or touch ?? provided 777 permissions are already there on file

I have a file, to which i have given 777 permission in unix.
Is there a way to restrict other users from editing this file from vi or touch.
Only other programs or >> can write into this file.
you can encrypt the file using RSA or SHA package in Unix,.
To encrypt use cmd
gpg -c yourfile
this will prompt for password give as you like. it will create yourfile.gpg
mv yourfile.gpg yourfile
to decrypt the file
gpg yourfile

Change File Encoding to utf-8 via vim in a script

I just got knocked down after our server has been updated from Debian 4 to 5.
We switched to UTF-8 environment and now we have problems getting the text printed correctly on the browser, because all files are in non-utf8 encodings like iso-8859-1, ascii, etc.
I tried many different scripts.
The first one I tried is "iconv". That one doesn't work, it changes the content, but the file's encoding is still non-utf8.
Same problem with enca, encamv, convmv and some other tools I installed via apt-get.
Then I found a python code, which uses chardet Universal Detector module, to detect encoding of a file (which works fine), but using the unicode class or the codec class to save it as utf-8 doesn't work, without any errors.
The only way I found to get the file and its content converted to UTF-8, is vi.
These are the steps I do for one file:
vi filename.php
:set bomb
:set fileencoding=utf-8
:wq
That's it. That one works perfect. But how can I get this running via a script?
I would like to write a script (Linux shell) which traverses a directory taking all php files, then converting them using vi with the commands above.
As I need to start the vi app, I do not know how to do something like this:
"vi --run-command=':set bomb, :set fileencoding=utf-8' filename.php"
Hope someone can help me.
This is the simplest way I know of to do this easily from the command line:
vim +"argdo se bomb | se fileencoding=utf-8 | w" $(find . -type f -name *.php)
Or better yet if the number of files is expected to be pretty large:
find . -type f -name *.php | xargs vim +"argdo se bomb | se fileencoding=utf-8 | w"
You could put your commands in a file, let's call it script.vim:
set bomb
set fileencoding=utf-8
wq
Then you invoke Vim with the -S (source) option to execute the script on the file you wish to fix. To do this on a bunch of files you could do
find . -type f -name "*.php" -exec vim -S script.vim {} \;
You could also put the Vim commands on the command line using the + option, but I think it may be more readable like this.
Note: I have not tested this.
You may actually want set nobomb (BOM = byte order mark), especially in the [not windows] world.
e.g., I had a script that didn't work as there was a byte order mark at the start. It isn't usually displayed in editors (even with set list in vi), or on the console, so its difficult to spot.
The file looked like this
#!/usr/bin/perl
...
But trying to run it, I get
./filename
./filename: line 1: #!/usr/bin/perl: No such file or directory
Not displayed, but at the start of the file, is the 3 byte BOM. So, as far as linux is concerned, the file doesn't start with #!
The solution is
vi filename
:set nobomb
:set fileencoding=utf-8
:wq
This removes the BOM at the start of the file, making it correct utf8.
NB Windows uses the BOM to identify a text file as being utf8, rather than ANSI. Linux (and the official spec) doesn't.
The accepted answer will keep the last file open in Vim. This problem can be easily resolved using the -c option of Vim,
vim +"argdo set bomb | set fileencoding=utf-8 | w" -c ":q" file1.txt file2.txt
If you need only process one file, the following will also work,
vim -c ':set bomb' -c ':set fileencoding=utf-8' -c ':wq' file1.txt
