      How easy is it to crack an AES encrypted 7Zip file?

      Only one way to find out 🙂

      Gimme an encrypted zip with a document, I'll post the contents of the document for you if I can get into it.

                @Breffni-Potter did you get a chance to download the cracking tool and fire it up?

                  If it helps, I can tell you that the password isn't "password123" or any derivative thereof.

                    Sorry guys.

                    Was away for a few days 😛

                    Will do so shortly.

                      Wolverhampton Wanderers are the greatest football team the world has ever known.

                      Is a lie.

                      Also could you set a password next time 😛

                        How long did it take to crack once you started the program? I was going to try it but the common software for breaking into 7zip is Windows only.

                          You should post a new thread talking about how easily 7zip security is to break too.

                          I wonder how hard the new Microsoft WiFi password sharing is going to be to break given that it is a similar mechanism.

                            0 Seconds.

                            I never actually tried opening it normally. The OP never set a password 😄

                              Sat down at my work-station, down-loaded the file again.

                              Double clicked...It opened.

                              Opened the file inside.

                              Copy pasted the text.

                              Instant success, zero effort.

                              Should have done that straight away, would have looked like a pro :bowtie:

                                  😳 I'm clearly a typical user! I'll try again in a bit.

                                    My second go. I've probably screwed this up as well!

                                    Proof, if any is needed, that the biggest threat to security is basic human error. All the software encryption in the world won't help if you're simply an idiot.

                                          So double click test says....

                                          There is a password stopping me from reading/extracting the file.

                                          But I can see the "newsecretdoc.txt" file - Just can't read it yet.

                                            Yeah, encrypting file names is optional in 7-zip.
