Why by clicking on an attached file of MS launched protected Word file and allows you to bypass the password protection?

Using Thunderbird 24.6.0 Windows 7
I got a MS Word (docx format) file as an attachment. The file is protected by password with the password that is provided in a separate e-mail.
To launch the file, I double-clicked on the attachment icon.
The file opens and displays the full content without prompting for the password.
(Save the file on my computer and opening it from the word trigger the prompt of password as expected.)

The whole point of sending files protected by password by e-mail, it's that anyone intercepting the file would not be able to open it without the password. Why Thunderbird bypasses this protection?

seriously you and you associate should investigate with S/Mime.

While the cost of commercial certificates, they are free to Comodofor personal use, so learning can be done without cost.

But if the two of you have a certificate and install it. (you need to digitally sign your mail.) encryption of mail content including attachments are as simple as click on Options menu > encrypt this message when you compose your mail.

No password, no e-mail with password and attachments in another mail. On your side, you get a guarantee that the message you receive is unchanged since that he showed when he was sent, and anyone who intercepts the message in transit would need to the key that is installed on the computer of the recipient to decode the content, in contrast to the normal plain which is sent text. And you don't notice anything else than a few icons when you read the mail that the decryption is done on the fly.

Note that email certificates are sent to your browser when you click on a link in an email from the provider must be exported from the browser certificate store and imported into Thunderbird certificate store.

  • How to stop Firefox playing mp3 files and allow me to save the file

    I've upgraded to Firefox v28. I want to record an mp3 file to play later as earlier versions of Firefox. When I click on the file, it starts playing and does not give me the option to save the file.

  • Windows 7 Media Player will not update files and allow me to remove the old files of the library.

    I've been deleting old audio/video files on my computer that also appear in the media player library but when I remove it from the library, it won't let me, but it gives me the options and it will show a pop window of the process he goes through to remove these old library files, but nothing to really occurs because the files remain in the library.

    (I guess that Afzal post ended up somehow in the wrong thread).

    To get rid of the old songs and videos in the library, you probably need to reset the media library. Note firstly reset the library will make you lose all play counts and ratings too. Then, follow these steps:

    -Restart the PC.
    -Click Start, type services.msc in the search field and press ENTER. In Services, locate the Windows Media Player Network Sharing Service . If its status is started , double-click the service, and then click stop .
    -Click Start, type %LOCALAPPDATA%\Microsoft in the search field and press ENTER. This folder opens in Windows Explorer.
    -In this folder, rename the folder Media Player as Old Media Player . If you do not see the folder, then it is probably hidden. Set Explorer to view the hidden files and folders and show protected system files.
    -Launch WMP, your library will have been reset and will be rebuilt.

  • XP pro guest password file and sharing - how to activate the password of comments?

    Hello

    I want to share files between two computers in Windows XP pro. I also wish that these actions are accessible only with a password.

    Here's a description of my installation:

    I have two laptops: more than 1 yo Fujitsu - Siemens (FS) running on Windows XP pro (Finnish) and a brand new Thinkpad T61 (TP) running on Windows XP pro (English). Theses computers have active as guest account these accounts have also been password protected. Guest of FS account is called "vieras" because language settings and guest account of TP is obviously just "invited". Passwords comments have been activated using the "net user ."

    Success!

    I solved my problem by changing guest passwords. I tried to keep it simple by using the same password for comments on both computers. This however allowed FS log TP without password of comments for some reason. My logic told me that having the same guest password would allow two computers to connect without password but it obviously wasn't the case. I guess Windows has its own logic that I can't understand, or this question had something to do with different language configurations. In any case my actions now work as I want to work.

  • RV180 VPN connects and allows you to browse the files, but falls when opening a file.

    Last week, we received our 300Mbps fiber connection. We bought the RV180 due to its high performance, and he manages the speed perfectly.

    However, when you set up VPN, I encountered a strange problem.

    Establishing a QuickVpn or PPTP is simple and connection is no problem. But I'll be fine. I can communicate with QuickVpn or PPTP and find a NAS or PC directory structure, but when I try to open a file the VPC connection drops.

    I activate the remote management.
    I can ping google.com f-l 1472 without fragmentation, so a WAN MTU of 1500 should be ok.
    I have tried disabling attack prevention firewall.

    I have install the following experience: the firmware update (1.0.2.6), restore the default settings.

    Set up the RV180 as follows:

    IPv4 WAN (Internet)

    ------------------------------------------------------------------

    Internet connection type: Automatic Configuration - DHCP

    DNS Server Source: Get dynamically for ISP

    MAC address of the router: use the default address

    End of series: 192.168.75.254

    Port number: 443

    Remote SNMP: disabled

    The rest of the menu options are, except for logging policies where I have everything turned on by default.

    In this experiment, I connect from a remote location, start navigating among directories of the drive without any problems and then open a file, after which the VPN connection falls (or some process breaks down). After the transfer of a few 100 KB blocks the VPN connection.
