This project is for Arkansas Public Schools to set their students HAC passwords to a predefined password. Unfortunately we couldn't use Powershell to accomplish this task as parts of the student profile page is rendered via Javascript. This project invokes a headless browser and submits the tasks as needed.

This project has been changed from node.js using Puppeteer to Powershell using Selenium. This process now takes about 5:30 to set up 100 students.

ChromeDriver.exe and the Selenium WebDriver.dll are included in this project:

• https://chromedriver.chromium.org/downloads
• https://www.nuget.org/packages/Selenium.WebDriver

We must download Chromium v110 separately as it is too large for github.

Manual Steps

• https://commondatastorage.googleapis.com/chromium-browser-snapshots/index.html?prefix=Win_x64/
• From this site, https://omahaproxy.appspot.com/, we can see that the latest v110 is branch_base_position:1084008
• Searching here: https://commondatastorage.googleapis.com/chromium-browser-snapshots/index.html?prefix=Win_x64/ we look for the closest to 1084008 which at the time of this writing is 1084068.
• https://commondatastorage.googleapis.com/chromium-browser-snapshots/index.html?prefix=Win_x64/1084068/
• Download chrome-win.zip and extract to bin\chrome-win

Automatic Method (possible breakage on URL changes.)

Invoke-WebRequest -Uri "https://www.googleapis.com/download/storage/v1/b/chromium-browser-snapshots/o/Win_x64%2F1084068%2Fchrome-win.zip?alt=media" -OutFile "$($env:temp)\chrome-win.zip"
Expand-Archive -Path "$($env:temp)\chrome-win.zip" -DestinationPath .\bin\ -Force

This project will use the default CognosModule profile by default. If you wish to use other credentials you can specify the CognosModule profile name with the -CognosConfig parameter.

Command Line

hac_passwords.ps1 [-CognosConfig <String>] [-CSV <String>] [-ForcePasswordChange] [-DisplayProgress]

Errors

Errors will be stored at .\logs\errors.csv so you can parse it and take additional actions afterwards.

CSV Example

students.csv

Student_id,Student_loginid,Student_password
801001234,[email protected],P@ssw0rd
801001235,[email protected],P@ssw0rd2

.\hac_passwords.ps1 -CSV students.csv

Stdin Pipe

'Student_id,Student_loginid,Student_password
801001234,[email protected],P@ssw0rd
801001235,[email protected],P@ssw0rd2' | .\hac_passwords.ps1

Think Bigger!

You would need to use some logic here to only set passwords for students who need it. Don't be setting all students over and over.

Invoke-SqlQuery -Query "SELECT Student_id,Student_email AS Student_loginid,Password AS Student_password" | ConvertTo-CSV | .\hac_passwords.ps1
