Facebook supporting now the stronger encryption

It has been now demonstrated that sometimes left hand does not know what the right hand is doing. Facebook is now pushing for stronger encryption.

Facebook now lets  users to add OpenPGP public keys to their profile, and to sign up for encrypted Facebook notifications.

Though legal for decades now, intelligence agencies have warned that widespread use of strong encryption could endanger their data-gathering efforts.


How it works: Facebook now allows users to upload their public keys onto their profile, where they can be made visible to friends or to the public, just like other contact information is. Facebook  further offers the option of encrypting notifications it sends to your email account. This provides some added protection, and also prevents your email provider from learning what you’re doing on Facebook.

If you use Gmail and have configured Facebook to send you all the notifications you can possibly configure in your Facebook settings to your Gmail account, obviously Facebook would be feeding Google ... lots of interesting information that Google could stuff into [its] database.

Using this feature further means that if your email account is hacked, or messages intercepted in transit, your Facebook notifications will be safe from prying eyes. Thorsheim believes that password reset requests are where this is most important.

There are lots of software and utilities available on the internet that can convert your video or audio files into the another formats like .avi, .wmv, .wav, .flv, .mov, .mp3, .aif, .3gp, etc...

Most of them are with paid features and if you could not pay then those softwares places some watermark on your vidoe files which looks awkward.

FFmpeg is the leading multimedia framework, able to decode, encode, transcode, mux, demux, stream, filter and play pretty much anything that humans and machines have created.

As well as ffmpeg, ffserver, ffplay and ffprobe which can be used by end users for transcoding, streaming and playing.

We can use FFMPEG in our code behind using vb.net or any other programming launguage and can make our life easy in order to processing video or audio files.

Below is a sample code for your reference that how we can call this ffmpeg.exe file in our code behind and process our required video or audio files.

Protected Sub btnSave_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSave.Click   

    Dim strArgu As String, strNewFileName As String
       
    '--- Converting into MP4 file
        strArgu = " -i """ + Server.MapPath("<Source Directory>/" & <source file name>) + """ -s 480x320 -vcodec libx264 -acodec libfaac -ar 16000 -r 13 -ab 32000 -aspect 3:2 """ + Server.MapPath("<Target Directory>/" & <target file name.mp4>) + """"
   
    '--- Converting into MP3 file
    strArgu = " -i """ + Server.MapPath("<Source Directory>/" & <source file name>) + """ -f mp3 -acodec libmp3lame -ab 192000 -ar 44100 """ + Server.MapPath("<Target directory>/" & <target file name.mp3>) + """"


        Dim proc As New Diagnostics.Process
        proc.StartInfo.Arguments = strArgu
        proc.StartInfo.FileName = Server.MapPath("ffmpeg.exe")
        proc.StartInfo.UseShellExecute = False
        proc.StartInfo.CreateNoWindow = True
        proc.StartInfo.RedirectStandardOutput = False

        Try
