ConvertFrom-SddlString

ConvertFrom-SddlString
    [-Sddl] <String>
    [-Type <Object>]
    [<CommonParameters>]

The ConvertFrom-SddlString cmdlet converts a Security Descriptor Definition Language string to a custom PSCustomObject object with the following properties: Owner, Group, DiscretionaryAcl, SystemAcl and RawDescriptor.

Owner, Group, DiscretionaryAcl and SystemAcl properties contain a readable text representation of the access rights specified in a SDDL string.

This cmdlet was introduced in PowerShell 5.0.

$acl = Get-Acl -Path C:\Windows
ConvertFrom-SddlString -Sddl $acl.Sddl

The first command uses the Get-Acl cmdlet to get the security descriptor for the C:\Windows folder and saves it in the variable.

The second command uses the ConvertFrom-SddlString cmdlet to get the text representation of the SDDL string, contained in the Sddl property of the object representing the security descriptor.

$acl = Get-Acl HKLM:\SOFTWARE\Microsoft\
ConvertFrom-SddlString -Sddl $acl.Sddl -Type RegistryRights

The first command uses the Get-Acl cmdlet to get the security descriptor for the HKLM:\SOFTWARE\Microsoft\ key and saves it in the variable.

The second command uses the ConvertFrom-SddlString cmdlet to get the text representation of the SDDL string, contained in the Sddl property of the object representing the security descriptor.

It uses the -Type parameter to specify that SDDL string represents a registry security descriptor.

$acl = Get-Acl -Path HKLM:\SOFTWARE\Microsoft\

ConvertFrom-SddlString -Sddl $acl.Sddl | ForEach-Object {$_.DiscretionaryAcl[0]}

BUILTIN\Administrators: AccessAllowed (ChangePermissions, CreateDirectories, Delete, ExecuteKey, FullControl, GenericExecute, GenericWrite, ListDirectory, ReadExtendedAttributes, ReadPermissions, TakeOwnership, Traverse, WriteData, WriteExtendedAttributes, WriteKey)

ConvertFrom-SddlString -Sddl $acl.Sddl -Type RegistryRights | ForEach-Object {$_.DiscretionaryAcl[0]}

BUILTIN\Administrators: AccessAllowed (ChangePermissions, CreateLink, CreateSubKey, Delete, EnumerateSubKeys, ExecuteKey, FullControl, GenericExecute, GenericWrite, Notify, QueryValues, ReadPermissions, SetValue, TakeOwnership, WriteKey)

The first command uses the Get-Acl cmdlet to get the security descriptor for the HKLM:\SOFTWARE\Microsoft\ key and saves it in the variable.

The second command uses the ConvertFrom-SddlString cmdlet to get the text representation of the SDDL string, contained in the Sddl property of the object representing the security descriptor.

It doesn't use the -Type parameter, so the access rights shown are for file system.

The third command uses the ConvertFrom-SddlString cmdlet with the -Type parameter, so the access rights returned are for registry.

$user = [adsi]"LDAP://CN=username,CN=Users,DC=___domain,DC=com"
ConvertFrom-SddlString $user.psbase.ObjectSecurity.Sddl -Type ActiveDirectoryRights

The first command uses Active Directory Service Interfaces (ADSI) to get the user object and saves it in the variable.

The second command uses the ConvertFrom-SddlString cmdlet to get text representation of the SDDL string, contained in the Sddl property of the object representing the security descriptor.

It uses the -Type parameter to specify that SDDL string represents an Active Directory security descriptor.

This cmdlet supports the common parameters: -Debug, -ErrorAction, -ErrorVariable, -InformationAction, -InformationVariable, -OutBuffer, -OutVariable, -PipelineVariable, -ProgressAction, -Verbose, -WarningAction, and -WarningVariable. For more information, see about_CommonParameters.

You can pipe a SDDL string to this cmdlet.
