The #base64 command has a wrap option. If it is set to 0 then you basically have created a base64 stream (without any EOL's). Which comes in handy for my #xor project.
Development btw is published when I have internet connection;

I realized that #encryption is not easy. Adjusted my goal from building a full blown Rijndael #cipher to a more simple xor block cipher. For educational purposes only!

Now I am more or less ready with the #base64 encoding of the input (#plaintext and #key), conversion to #ASCII #hex and then creating #binary codes. Then the plaintext has to be split into 16 byte blocks, which are to be #xor-ed with the key.

Todo: key-rotation, to make the algorithm stronger.

Today I learned: all the above. But especially how valuable base64 encoding is for converting non-ASCII characters.

Okay, I now want to write the Rijndael algorithm (AES) in bash.
Is that even possible?
Any suggestions appreciated!
Wish me luck. 😃

isolatest, the tool to download an up-to-date archiso has been moved to hajime, the archlinux installation tool.

Please update your local repos and have a nice day!

passr is the password-store wrapper I developed and use on a daily basis.

Today I improved the autoentry function with an audible cue, customizable fields and input duration.

Adding ``aeseq: url:5 userid:5 password:5`` to your pass-file will wait 5 seconds until the next field value.
passr also says (with e-speak) which field value is loaded.
Works pretty cool!

Currently my Linux experience; One rabbit hole covered, looking back, three new rabbit holes arisen...
I somehow have totally broken my DNS. Seems to be lots of layers of which I have no clue about...

After more than 5 years of trustworthy use, I discarded my old hasher 'pwgn' and replaced it with a brand new 'pwg2'.

'Pwg2' is based on the widely implemented and appreciated Argon2 hash function. The script became incredibly more shorter and simpler. Also because of Argon2 the execution time is dramatically reduced. All in all another productive day!

Please test the script if you like and report back any vulnerabilities. Thank you!

After wiping my main system, which is not so old and has an nvme drive, during instllation hajime came to a standstill while attempting to execute sgdisk. I went to sleep and dreamt my solution should be in line 621?! Now see if it works...

Hajime is finished! I consider it in production from now on.
If you have a spare machine, check it out. A quick offline installation (modules 1-3) will be ready within a couple of minutes.

Working on a method of installing offline yay packages from an alternate location. Any suggestions are welcome.

Installing #archlinux with all essential application configuration in under 15 minutes! With or (even faster) without network internet connection. Have some spare time left? Use the interactive installation instead.

Happy with hajime, an arch linux installation script that comes in five modules.

@Codeberg
My browser shows no codeberg in the title, but forgejo stuff, which is confusing.
Is this on purpose or did you forget to update?

Here my quick build of a bash toml parser based on kwmiebach's (https://github.com/kwmiebach) version on github. Thanks kwmiebach!
https://codeberg.org/oxo/tool/src/branch/main/toml-read

The order of arguments (file, section key) is irrelevant. Data is aggregated if no key or section is given.

My idea is to integrate it with my paasword manager passr. Then my password files can be toml format.

Have a nice weekend!
