## Verification
|
||||
|
||||
This bundle includes verification scripts to ensure integrity. Choose your platform:
|
||||
|
||||
### Unix/Linux/macOS (Bash)
|
||||
|
||||
```bash
|
||||
chmod +x verify.sh
|
||||
./verify.sh
|
||||
```
|
||||
|
||||
**Requirements:** `sha256sum` (installed by default on most systems)
|
||||
|
||||
### Windows (PowerShell)
|
||||
|
||||
```powershell
|
||||
# May need to adjust execution policy
|
||||
Set-ExecutionPolicy -ExecutionPolicy Bypass -Scope Process
|
||||
.\verify.ps1
|
||||
```
|
||||
|
||||
**Requirements:** PowerShell 5.1 or later (included in Windows 10+)
|
||||
|
||||
### Cross-Platform (Python)
|
||||
|
||||
```bash
|
||||
python3 verify.py
|
||||
```
|
||||
|
||||
**Requirements:** Python 3.6 or later
|
||||
|
||||
### Manual Verification
|
||||
|
||||
You can also manually verify checksums using standard tools:
|
||||
|
||||
```bash
|
||||
# On Linux/macOS
|
||||
sha256sum -c checksums.sha256
|
||||
```
|
||||
|
||||

|
