Escape sequence in registry path

[DaveM]

Does anyone know how to escape a forward slash in a registry path?

This is an actual registry path and the back tick does not seem to work.

set-location
"HKLM:\System\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Ciphers\DES
56`/56"

I found some documentation that talks about WSH not supporting the use
of the slash in a registry key, but WMI does.

Does anyone know if this is also true for powershell?

Thanks for any help.

Hi Dave,

Escaping the forward slash / with the PS back tick will never change
anything, since from a string syntax perspective / is not a special character
that may behave differently when quoted.

Unfortunately it looks like PS does not support / in a registry key name at
all, even though / is an absolutely acceptable key name character for the
Win32 registry API. I assume this is because PS in general treats both,
forward slash and backslash, as acceptable element separator chars for any
kind of path and therefore / never can be part of any path element name.
Get-ChildItem does not even retrieve existing keys which contain a / in their
name.

I rate this as a serious flaw of the PS registry provider, but have no
workaround suggestion other than to use alternate command line registry tools.

I agree with Gerd,

but this might be a bit less silly as I did think :

this might work for editing it, do not know a workaround to create, but
might be possible using .NET directly, also :

PS HKLM:\> cd hklm:;(get-psdrive hklm).CurrentLocation =
'HKLM:\System\CurrentControlSet\Control\SecurityProvi
ders\SCHANNEL\Ciphers\DES\56`/56'
PS
HKLM:\System\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Ciphers\DES\56`/56> ls

h.t.h.

Gerd and MOW, Thanks for the confirmation.

It also looked like a flaw in the registry provider to me.

I believe I have a workaround using [Microsoft.Win32.RegistryHive]

Thanks again

The workaround in case anyone is interested.

$KeyPath =

'HKLM:\System\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Ciphers\DES

56/56'
$RegType = [Microsoft.Win32.RegistryHive]::LocalMachine
$regKey = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey($RegType,
$Env:Computername)
$regKey = $regKey.OpenSubKey($KeyPath, $TRUE)
if( -not $regKey.GetValue("Enabled")){
$regKey.SetValue("Enabled", 0, [Microsoft.Win32.RegistryValueKind]::DWord)
}
else
{
$regKey.SetValue("Enabled", 0, [Microsoft.Win32.RegistryValueKind]::DWord)
}

Thanks,

Dave M
