Invalid or corrupt authenticity information – WinRAR ERROR Message

Unextracting WinRAR Archive Error – Invalid or corrupt authenticity information

QUESTION:

Help! I am getting an error message when I try to un-extract a RAR archive:

“Invalid or corrupt authenticity information”

What does the error “Invalid or corrupt authenticity information” mean?

ANSWER:

It means the person who compressed the WinRAR archive you are unextracting used an old version of the WinRAR software. (Or archived the files a while back, and you are using a new version of the software.)

This error message will NOT affect the contents of the archive you are extracting.

For example, if you are unextracting a video and get this error message, ignore it and allow the unarchiving process to finish. Once it is complete play you video to ensure it works properly. As you can see the contents of the WinRAR archive should be unaffected by the error.

“Invalid or corrupt authenticity information”

If you do have a problem with the contents of the archive it is probably unrelated to the error itself, and has something to do with corruption that occurred when downloading the RAR archive.

If this is the case you may want to try doing a “Repair” on the archive through WinRAR.

SOLUTION:

Ignore the error message, plain and simple. It will not affect the contents of the Archive. It cannot be fixed by using a newer version of WinRAR as the issue is a result of older software to begin with.
