    .DESCRIPTION

    Out-ObfuscatedAst obfuscates PowerShell scripts using AbstractSyntaxTree-based obfuscation rules.

    .PARAMETER ScriptString

    Specifies the string containing the script to be obfuscated.

    .PARAMETER ScriptBlock

    Specifies the ScriptBlock containing the script to be obfuscated.

    .PARAMETER ScriptPath

    Specifies the Path containing the script to be obfuscated.

    .PARAMETER ScriptUri

    Specifies the Uri of the script to be obfuscated.

    .PARAMETER AbstractSyntaxTree

    Specifies the root Ast that represents the script to be obfuscated.

    .PARAMETER AstTypesToObfuscate

    Specifies the Ast Types within the root Ast that obfuscation should be applied to. Defaults to all types with obfuscation implemented.

    .PARAMETER DisableNestedObfuscation

    Specifies that only the root Ast should be obfuscated, obfuscation should not be applied recursively.

    .OUTPUTS

    String

    .EXAMPLE

    Out-ObfuscatedAst -Ast $AbstractSyntaxTree
