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
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.
Flash Player installers are digitally signed. You can check to see if they are signed by Adobe:
- Launch Terminal (/Applications/Utilities/Termina.app)
- 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
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
