How to read/edit store.dat on Windows

What this does

• Decrypts %AppData%\rIDE\<userId>\store.dat using Windows DPAPI (CurrentUser).
• Lets you view keys and update a value (e.g., GithubToken, SupabaseToken, etc.).
• Must be run as the same Windows user account that created the file.

---

0) One-time setup

1. Save the script (name it exactly): decrypt-dat-file.ps1
   (Use the version Jimmy shared --- it already loads the System.Security assembly and includes Set-StoreValue.)

2. Put it somewhere easy, e.g.:

   C:\Users\<you>\OneDrive\Desktop\Codebuddy\decrypt-dat-file.ps1
   

---

1) Open PowerShell & allow running the script (this session only)

Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass

---

2) Find your userId folder and back up the file

store.dat lives at:

%AppData%\rIDE\<userId>\store.dat

In PowerShell, reference %AppData% as $env:APPDATA. Example:

# Replace <userId> with the actual folder name (GUID)
cd "$env:APPDATA\rIDE\<userId>"
Copy .\store.dat .\store.bak

Tip: to list the available userId folders:

Get-ChildItem "$env:APPDATA\rIDE"

---

3) List keys / read values (no edits yet)

Option A --- run the script with parameters (no functions loaded)

Use the call operator & when passing parameters:

& "C:\Users\<you>\OneDrive\Desktop\Codebuddy\decrypt-dat-file.ps1" -UserId "<userId>" -ListKeys
# Example output: GithubToken, SupabaseToken, AzureAccessToken, ...

Read a specific key:

& "C:\Users\<you>\OneDrive\Desktop\Codebuddy\decrypt-dat-file.ps1" -UserId "<userId>" -Key GithubToken -Raw

-Raw prints the exact string. Without -Raw, JSON values (like SupabaseToken) are pretty-printed.

---

4) Edit a value

You have two ways to edit:

Option A (recommended): dot-source once, then call Set-StoreValue

Dot-sourcing loads the helper functions into your shell:

. "C:\Users\<you>\OneDrive\Desktop\Codebuddy\decrypt-dat-file.ps1"

Now update a key:

• Plain string key (e.g., GithubToken):

Set-StoreValue -UserId "<userId>" -Key "GithubToken" -Value "ghp_or_ghu_yourNewTokenHere"

• JSON key (e.g., SupabaseToken expects JSON):

$newPat = '{"AccessToken":"myNewSupabasePAT","RefreshToken":null,"ExpiresAt":"2025-12-31T23:59:59Z"}'
Set-StoreValue -UserId "<userId>" -Key "SupabaseToken" -Value $newPat

Verify:

& "C:\Users\<you>\OneDrive\Desktop\Codebuddy\decrypt-dat-file.ps1" -UserId "<userId>" -Key GithubToken -Raw
# or
& "C:\Users\<you>\OneDrive\Desktop\Codebuddy\decrypt-dat-file.ps1" -UserId "<userId>" -Key SupabaseToken

Option B: stay "no functions" and only run the script

Use this only to view or list; editing requires Option A.

5) Common pitfalls & fixes

• The term 'Set-StoreValue' is not recognized
  You ran the script but didn't dot-source it. Dot-source first:

  . "C:\Users\<you>\OneDrive\Desktop\Codebuddy\decrypt-dat-file.ps1"
  

• Unable to find type [System.Security.Cryptography.ProtectedData]
  Use the script Jimmy provided (it includes Add-Type -AssemblyName System.Security).
  If you still see it:

  Add-Type -AssemblyName System.Security
  

• DPAPI Unprotect failed...
  You're not running as the same Windows user that created the file. Switch to that user profile.

• %AppData% doesn't work in PowerShell
  Use $env:APPDATA (PowerShell style):

  cd "$env:APPDATA\rIDE\<userId>"
  

• Edited value shape

  • Keys like GithubToken are plain strings.\
  • Keys like SupabaseToken and projectSecret_* are JSON. Make sure you pass valid JSON.

6) Quick examples (ready to paste)

List keys

& "C:\Users\<you>\OneDrive\Desktop\Codebuddy\decrypt-dat-file.ps1" -UserId "<userId>" -ListKeys

Read GitHub token (raw)

& "C:\Users\<you>\OneDrive\Desktop\Codebuddy\decrypt-dat-file.ps1" -UserId "<userId>" -Key GithubToken -Raw

Update GitHub token

. "C:\Users\<you>\OneDrive\Desktop\Codebuddy\decrypt-dat-file.ps1"
Set-StoreValue -UserId "<userId>" -Key "GithubToken" -Value "ghp_or_ghu_yourNewTokenHere"

Update Supabase token (JSON)

. "C:\Users\<you>\OneDrive\Desktop\Codebuddy\decrypt-dat-file.ps1"
$newPat = '{"AccessToken":"myNewSupabasePAT","RefreshToken":null,"ExpiresAt":"2025-12-31T23:59:59Z"}'
Set-StoreValue -UserId "<userId>" -Key "SupabaseToken" -Value $newPat

Verify

& "C:\Users\<you>\OneDrive\Desktop\Codebuddy\decrypt-dat-file.ps1" -UserId "<userId>" -Key GithubToken -Raw
& "C:\Users\<you>\OneDrive\Desktop\Codebuddy\decrypt-dat-file.ps1" -UserId "<userId>" -Key SupabaseToken
