    "The request is not supported" error on cipher command


    Hi, i just want to secure my personal file on my PC using cipher command on cmd. Here i input the command:


    C:\Windows\system32>cd C:\Users\User\Desktop\Yada


    C:\Users\User\Desktop\Yada>cipher /e


    What i expect:


    Encrypting files in C:\Users\User\Desktop\Yada\



    Stuff.txt [OK]


    1 files [or directories] within 1 directories were encrypted


    Reality:


    Encrypting files in C:\Users\User\Desktop\Yada\



    Stuff.txt [ERR]

    Stuff.txt: The request is not supported.


    0 files [or directories] within 1 directories were encrypted


    Here's my PC's spesification:


    Windows edition:

    Windows 10 Home


    Processor:

    AMD A4-9125 RADEON R3, 4 COMPUTE CORES 2C+2G 2,30 GHz

    Installed memory RAM: 4,00 GB

    System type: 64-bit OS, X64-based processor


    I tried multiple times, it didn't work. So if anyone know how to fix this, please reply it

    :)

  2. Cipher Error : The Request is not supported.


    Upon trying to use Cipher to do some simple encrypting on my machine I have ran into some issues.

    "The request is not supported" error on cipher command [​IMG]

    If I execute Cipher.exe from the Command Prompt it seems to be functioning normally and subsequently lists all folders on the current directory with a U in front of them indicating that they are unencrypted, however, when I attempt to encrypt a directory ... or rather the files within it ... I get an error that reads " The request is not supported " beside each file listed in the directory and an overall summery that 0 files were encrypted.

    I noticed that there is no Cipher.dll file on my machine, as according to some due diligence research, perhaps should have been. I located the only cipher.dll I could find, however, upon trying to register it I received an error that " the module was downloaded but the entry point DllRegisterServer was not found. I also found an update on Microsoft's website, (KB4032188), that claimed to resolve known Cipher issues, however, was unable to install it on my machine as it kept stating that the update was not applicable to the particular Windows 10 build I am running. I also tried to use TLS 1.0 only and still received the same error. Any ideas?

    CMD cipher /e on a folder output "Request not supported"

    I've recently discovered cipher command on windows-10 command-line.

    Now, the problem is when I'm try to execute cipher /e [directory name] or cipher /e [absolute path], because I'm always receiving the error [directory name]: Request not supported..

    Some useful info:

    • I'm running Microsoft Windows 10 Home
    • I've executed the command as administrator either on 'cmd' and 'powershell'
    • The disk's file system is in 'NTFS'.
    • I've gave all the access to all the users in the 'Security' attribute on the interested folder(An empty folder for test purposes).

    Could someone give me a hint/suggestion/solution about where the problem could be? Am I missing something important?

    "The request is not supported" error on cipher command

    Cipher suite mismatch error

    I have WCF service and a client accessing that service hosted on the same production machine(Windosw Server 2016 build)

    ) for testing purposes, but when the client pings the server, the call ends with an error:
    Could not establish secure channel for SSL/TLS with authority 'ServerName: Port'.

    When I checked the event logs, I found the following error

    An unknown connection request was received from a remote client application, but none of the cipher suites supported by the client application are supported by the server. The TLS connection request has failed. (SChannel - 36874)

    I tried enabling/disabling SSL, TLS security on the machine, but still not able to solve the issue.

    Is there any registry key I need to set to add specific Cipher Suite to solve this issue?

    Thanks in advance
