Raspberry Pi 3 headless wifi AP

this is a quick checklist, detailed description provided in the urls

write raspbian ISO image with pv/dd to microSD
mount ROOT and boot
touch /boot/ssh to enable ssh (important new req)
follow below steps described here in details
move /etc/init.d/rc2.d/K*ssh to S*ssh
edit /etc/wpa_supplicant/wpa_supplicant.conf and provide network {} section with AP SSID and password RPi should connect to

command to setup

git config --global alias.tree "log --date-order --date=short  --abbrev-commit --graph --decorate \
  --pretty=format:'%x09%C(yellow)%h | %Cred%ad | %Cblue%ae | %Cgreen%d %Creset%s'"

usage is just git tree with optional params to log command like i.e. git tree --all to show all branches

Client-Side Encryption:

To implement client-side encryption, we will use the Web Crypto API for encryption and decryption operations. We will ensure that the backend never has access to the plaintext data or encryption keys. First, let's create a function to generate a secure encryption key using the Web Crypto API:

async function generateEncryptionKey(): Promise<CryptoKey> {
  // Generate a new AES-GCM key
  const key = await crypto.subtle.generateKey(
    {
      name: "AES-GCM",
