    Where are the checksums for Flash Player?

      Considering there have been some fake Flash packages distributed and possibly downloaded by users. It would be excellent if Adobe provided checksums for their packages. There must be a way to do this.

       

      When I attempt to install a package I downloaded from Adobe I even get a warning. “Install Adobe Flash Player” is an application downloaded from the Internet. Are you sure you want to open it?

          Hi,

           

          We don't currently post the checksums for the installers.  I understand you're concern.   I'll forward your comment to the appropriate team for consideration.  As for the warning you're seeing, I'm guessing you're on a Mac.  This is standard security notification on Mac when launching an app installer downloaded from the internet.


          If you provide the name of the file you're using, I can post the checksum for it.  If it's the online installer, post the OS and browser combination you used to download it

            Hi Maria,

             

            Thanks. Yes, please forward the comment. I realize that is the standard Apple security notification. The point is that it's the same message whether it's a genuine Adobe product or whether it's not. The only way to know the difference between two apparently similar installers in your downloads folder is to have a checksum. With all of the issues regarding Plug-ins and security these days it's really a requirement and not optional.

             

            Thank you.

              Flash Player installers are digitally signed.  You can check to see if they are signed by Adobe:

               

              1. Launch Terminal (/Applications/Utilities/Termina.app)
              2. At the prompt Type: codesign -vvd <path to Flash Player.app> [ENTER]
                • for example: codesign -vvd /Volumes/Adobe\ Flash\ Player\ Installer/Install\ Adobe\ Flash\ Player.app
              3. The result should have the following in the output:

                Authority=Developer ID Application: Adobe Systems, Inc.

                Authority=Developer ID Certification Authority

                Authority=Apple Root CA
