# Fixing that old mess
So building the blog with html manually was a pain in the ass. But doing something like an MVC framework or a CMS for a simple blog seemed like too much hassle as well. I don't want a WYSIWYG, or something that's browser-based. I hate dealing with browser frontends. Afterall, a blog is mostly - if not *entirely* - text-based. Why should I have to deal with the overhead of a server-side scripted website? I just want to write my blog in markdown - like i do with all my documentation already. Then I could even keep it in a git repo, backed up to my private gitea instance.
The answer to all of that, is `static site generation`. Turns out, there are plenty of other people out there who have looked at available tools, thought something similar to me, then built their own new tool that can take markdown, then generate a whole-ass website with it. Simple, and clean. You write content, maybe tweak some CSS/HTML templates, then the generator handles all the dirty work. No more searching for dozens of instances of a link when I change something in the navbar. That navbar is now a single template file that's reused by the generator.

Bear in mind, this all required a bit of setup and learning to self-host. But, when the hosts & runners are all set up and running properly, with the above workflow, updating this blog is a simple matter of committing to a git repo then pushing it to my remote. The runners handle everything else.

Turns out, the makefile is fine. Super easy. Just gotta hit it with a `make` command and its primo. So what I did, was I made the mirrors org and moved my blag mirror over there. Then I forked it to my personal gitea account. Then I cloned the fork, and made a `v2.3.0` branch because it was on `v2.2.x`. I updated the version in the source. Then I added the dependency for the new package `pymdown-extensions` in the appropriate files. Then I modified the `markdown.py` file to include the `footnotes` and `pymdownx.tilde` (strikethrough) extensions. Then I ran the makefile, which did its magic and made the stuff. Then I simply run twine to upload to my personal gitea package repo. Done. Version 2.3.0 is on my repo.

I needed docker on my pi, so i abandoned freebsd. It was a good run and taught me a lot about unix. But implementing a custom freebsd server is just. not my thing anymore. Docker is so much easier for versioning. And if i want to compile from scratch? I have that option, too, with docker.
The pi now runs openSUSE Leap 15.6.
## How I do gitops
# How I do gitops
I've more or less solidified how I do gitops. When I need to version control files on a remote server, I make a local git repo with those files that also contains a script which is used to deploy any of said files on the remote server. This is achieved over SSH. A bare git repo is initialized on the remote server, and added as a remote in the gitops repo. Then, that remote is pushed to in a way that it is always synced perfectly with the local copy. Then, a script in the git repo can SSH into the remote, clone the repo from the local copy, and do stuff with the files.
## How the deployment server works.
# How the deployment server works.
Before, i used rootless docker and usernames to sort of namespace things in an ineffective way. I was also using gitea actions configs to do things on the deployment server with an ssh key that had unlimited access to the user account. This provided a false sense of security.

# So how do I do things?
Well, as I alluded to earlier - I work in my text editor, out of git repositories. All of my services are deployed with docker - its just... easier, this way. I've run services so many different ways over the years and docker is simply the easiest to deal with. I can grab premade containers. Or I can make my own, push them to my gitea deployment, and pull them for use later. Its great. And its distro agnostic. Sure there are some security issues associated with it. But there are also well documented methods to nullify them. I can also use docker volumes to store everything in `/opt/{container_name}` which is super handy when it comes time to archive/back up the host since all I need to do to grab any important data is backup `/opt`!

The authorized_keys file and `ci` folder allow me to use gitea actions to deploy docker images on the host. I generate an ssh keypair, I store the private key as a secret in each individual repo that deploys to the host, then i put the public key in the authorized_keys file with a command that points to a script in `ci` that pulls and redeploys docker images.

title: Using passwords in script, revisited!
description: Another look at my entry from 12th May, 2024 where I explore a method for obfuscating scripts to keep borg passphrases secure while automating my backup process.

# Revisiting an old topic
[In this blog entry dated 12th May, 2024](https://blog.raer.me/2024/05/01/20240512.html) I discuss a method where I'm able to keep passphrases stored inside of a bash script, while still being able to execute the bash script. Its been a few months and I've improved the process for obfuscating/deobfuscating scripts, since I'm now using this method as part of my process in writing/editing backup scripts. Thus I'd like to retouch the topic since rereading the previous blogpost leaves me a bit undersatisfied.
# The process
You start by writing a script, and don't forget to include your sensitive data. I'll include an example below of one of my backup scripts:
```bash
#!/usr/bin/env bash
NAME=pi_$(date +'%Y%m%d%H%M%S')
DIR="/home/freyja/.mnt/pi"
tmux new-session -d -s borg-pi-archive "sshfs pi:/opt $DIR; \
export BORG_PASSPHRASE=yesthisistotallymyrealpassphraseyougotmeididanoopsie; \
borg create --stats --progress --compression lz4 /home/freyja/Documents/.borg/pi::$NAME $DIR; \
export BORG_PASSPHRASE=''; \
rclone sync -P -v /home/freyja/Documents/.borg/pi proton:/borg/pi; \
umount $DIR; \
"
```
## Obfuscation
Obviously, saving this as plaintext would be insecure. It has a whole encryption passphrase in there! But remembering all that and typing it in every time isn't ideal either. That's where the `obfuscate` script comes in. That looks a 'lil somethin' like this:
```bash
#!/bin/bash
##
# obfuscate script. This will encrypt any script with a gpg id,
# then stick it into the body of a variable in a new script that can
# decrypt the variable and pipe the original script directly to bash.
#
##
if [ -z "$1" ]; then
read -p "Please enter the filename: " filename
else
filename="$1"
fi
GPG_ID='my-gpg-identity'
printf "#!/bin/bash\n\nSCRIPT=\"$(cat $filename | gpg --encrypt --armor -r $GPG_ID | base64 --wrap 0)\"\n\necho \$SCRIPT | base64 -d | gpg --decrypt --quiet | bash\n\n" > $filename.obf
chmod +x $filename.obf
```
calling that with `obfuscate script` will spit out a file called `script.obf` that is just as easy to execute as the script you obfuscated. In fact, it is literally that exact script! Except its been encrypted with your supplied `GPG_ID`, turned into base64, then stuck inside a variable called `SCRIPT` inside of the `script.obf` file - along with some other stuff that allows `script.obf` to decrypt the data stored in `SCRIPT` variable then pipe it directly into bash.
The obfuscated script will look a bit like this:
```bash
#!/bin/bash
SCRIPT="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"
echo $SCRIPT | base64 -d | gpg --decrypt --quiet | bash
```
## Deobfuscation
As you can see, the encrypted script is stored as base64. To run it, that script is decoded, decrypted, then piped into bash. So long as the machine you're on has the private key for the gpg key you used to encrypt the script, it will simply ask you for your gpg passphrase before proceeding~~! How neat! But what if we want to edit the script? Seems like a bit of a pain to get your original script back, right? Well... to a degree. If you wanted to, you could lop of that pipe and `bash` command at the end of the last script, replace it with `>> script.deobfuscated`, and you'd have your original script back. But, that's also kind of annoying to do every time. So I just made a `deobfuscate` script that'll do the job for you. Its just like the `obfuscate` script but in reverse. It takes a file as input, looks for a variable called `script`, then decodes, decrypts, and dumps it into a file appended with `.deobfuscated`. Here's the deobfuscate script:
```bash
#!/bin/bash
if [ -z "$1" ]; then
read -p "Please enter the filename: " SCRIPT_FILE
else
SCRIPT_FILE="$1"
fi
if [ ! -f "$SCRIPT_FILE" ]; then
echo "$SCRIPT_FILE not found!"
exit 1
fi
cat $SCRIPT_FILE | xargs | awk -F 'SCRIPT=' '{print $2}' | awk -F ' ' '{print $1}' | base64 -d | gpg --decrypt --quiet > $SCRIPT_FILE.deobfuscated
if [ $? -eq 0 ]; then
echo "$SCRIPT_FILE has been deobfuscated."
else
echo "Failed to decrypt the script. Ensure you have the correct GPG key and it's available."
exit 1
fi
```

That's about it, I don't have anything else. This section is simply a formality. I hope that if you're reading this, you find it interesting. <3

3. To the extent possible, the Licensor waives any right to
collect royalties from You for the exercise of the Licensed
Rights, whether directly or through a collecting society
under any voluntary or waivable statutory or compulsory
licensing scheme. In all other cases the Licensor expressly
reserves any right to collect such royalties, including when
the Licensed Material is used other than for NonCommercial
purposes.
Section 3 -- License Conditions.
Your exercise of the Licensed Rights is expressly made subject to the
following conditions.
a. Attribution.
1. If You Share the Licensed Material, You must:
a. retain the following if it is supplied by the Licensor
with the Licensed Material:
i. identification of the creator(s) of the Licensed
Material and any others designated to receive
attribution, in any reasonable manner requested by
the Licensor (including by pseudonym if
designated);
ii. a copyright notice;
iii. a notice that refers to this Public License;
iv. a notice that refers to the disclaimer of
warranties;
v. a URI or hyperlink to the Licensed Material to the
extent reasonably practicable;
b. indicate if You modified the Licensed Material and
retain an indication of any previous modifications; and
c. indicate the Licensed Material is licensed under this
Public License, and include the text of, or the URI or
hyperlink to, this Public License.
For the avoidance of doubt, You do not have permission under
this Public License to Share Adapted Material.
2. You may satisfy the conditions in Section 3(a)(1) in any
reasonable manner based on the medium, means, and context in
which You Share the Licensed Material. For example, it may be
reasonable to satisfy the conditions by providing a URI or
hyperlink to a resource that includes the required
information.
3. If requested by the Licensor, You must remove any of the
information required by Section 3(a)(1)(A) to the extent
reasonably practicable.
Section 4 -- Sui Generis Database Rights.
Where the Licensed Rights include Sui Generis Database Rights that
apply to Your use of the Licensed Material:
a. for the avoidance of doubt, Section 2(a)(1) grants You the right
to extract, reuse, reproduce, and Share all or a substantial
portion of the contents of the database for NonCommercial purposes
only and provided You do not Share Adapted Material;
b. if You include all or a substantial portion of the database
contents in a database in which You have Sui Generis Database
Rights, then the database in which You have Sui Generis Database
Rights (but not its individual contents) is Adapted Material; and
c. You must comply with the conditions in Section 3(a) if You Share
all or a substantial portion of the contents of the database.
For the avoidance of doubt, this Section 4 supplements and does not
replace Your obligations under this Public License where the Licensed
Rights include other Copyright and Similar Rights.
Section 5 -- Disclaimer of Warranties and Limitation of Liability.
a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE
EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS
AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF
ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS,
IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION,
WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR
PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS,
ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT
KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT
ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.
b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE
TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION,
NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT,
INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES,
COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR
USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN
ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR
DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR
IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.
c. The disclaimer of warranties and limitation of liability provided
above shall be interpreted in a manner that, to the extent
possible, most closely approximates an absolute disclaimer and
waiver of all liability.
Section 6 -- Term and Termination.
a. This Public License applies for the term of the Copyright and
Similar Rights licensed here. However, if You fail to comply with
this Public License, then Your rights under this Public License
terminate automatically.
b. Where Your right to use the Licensed Material has terminated under
Section 6(a), it reinstates:
1. automatically as of the date the violation is cured, provided
it is cured within 30 days of Your discovery of the
violation; or
2. upon express reinstatement by the Licensor.
For the avoidance of doubt, this Section 6(b) does not affect any
right the Licensor may have to seek remedies for Your violations
of this Public License.
c. For the avoidance of doubt, the Licensor may also offer the
Licensed Material under separate terms or conditions or stop
distributing the Licensed Material at any time; however, doing so
will not terminate this Public License.
d. Sections 1, 5, 6, 7, and 8 survive termination of this Public
License.
Section 7 -- Other Terms and Conditions.
a. The Licensor shall not be bound by any additional or different
terms or conditions communicated by You unless expressly agreed.
b. Any arrangements, understandings, or agreements regarding the
Licensed Material not stated herein are separate from and
independent of the terms and conditions of this Public License.
Section 8 -- Interpretation.
a. For the avoidance of doubt, this Public License does not, and
shall not be interpreted to, reduce, limit, restrict, or impose
conditions on any use of the Licensed Material that could lawfully
be made without permission under this Public License.
b. To the extent possible, if any provision of this Public License is
deemed unenforceable, it shall be automatically reformed to the
minimum extent necessary to make it enforceable. If the provision
cannot be reformed, it shall be severed from this Public License
without affecting the enforceability of the remaining terms and
conditions.
c. No term or condition of this Public License will be waived and no
failure to comply consented to unless expressly agreed to by the
Licensor.
d. Nothing in this Public License constitutes or may be interpreted
as a limitation upon, or waiver of, any privileges and immunities
that apply to the Licensor or You, including from the legal
processes of any jurisdiction or authority.
