How to make video files locked by password?

[kenny1999]

I have to send some video files (e.g. mpeg mpg avi etc) to my clients but there are some privacy issues so I want to add password to those videos. I've tried using winzip to zip the files because they can encrypt things with password but quite a number of my clients explained that they couldn't extract the files with my passwords. I think there must be some problems. Would anyone tell me why? Thanks

Hi!

Have you checked to see if YOU can extract them using the password?

Make sure you're using the .zip format, not .zipx. WinZip's proprietary format is .zipx, which requires the recipient to use WinZip to extract it. If they have WinRar or 7zip or something, for example, they wouldn't be able to open it. Also be careful when compressing photo and video files with WinZip. In order to increase compression, WinZip actually re-encodes some videos and photos in a lossy manner.

Use "universal extractor "to extract any archieve.

For sake of simplicity, you could use WinRAR to create a SFX (self-extracting) archive. You will get an EXE file that the use can extract by double-click. No software (not even WinRAR) will be needed.

If you make a password-protected SFX archive the user will of course be prompted the enter the password before the file extracts itself...

Maybe your clients don't know how to input a password, unless they have experience with them.
For instance, the point and the space are parts of the password, so anyone double-clicking on the email than copy/paste into Winzip would experience such issues.
Why do you need passwords anyway?

I haven't used WinZip for a while, but around v.10 or something breaking the password was a piece of cake.

Use 7zip instead.
Create a zip archive and encrypt using AES-256.
You can't make a self-extracting version and Windows' built-in unzip won't work.
But you can trust it won't be easily opened.

Make sure the archive and password to open it don't go in the same (e)mail...:)

And 7zip is free...

I have entered the password very very carefully , without capital letters, i have also reminded my clients to type in the password but not "copy and paste" because they may carelessly copy the blank at the end.

If only one or two clients by chance can't extract them , i will think that they don't know computer, but so many clients reflect that my zip files couldn't be extracted, then i suspect if there are any problems zipping videos with winzip

It may also happen that sometimes the downloads are defective, if this is the case, for various reasons. A SFV or other verification methods might be useful.
It also may be that you used a compression method not compatible to older versions, which is a big no no if you don't intend to use these files for you.

...i have also reminded my clients to type in the password but not "copy and paste"Actually, copy-paste is the best way to enter complex passwords.
This way you avoid the mixup between 0 and O, l and I, etc.

Just put the password in quotes and tell them to copy-paste everything between the quotes...

You responded, I have entered the password very very carefully , without capital letters, i have also reminded my clients to type in the password This is a "Yes or No" question. Please answer...
