Encrypt a file for email

Hello Experts,

I want a simple to use application where I can encrypt OR password protect a file to send via email.  I also would like it so the user on the otherside does NOT require any software but just the key or password.

I will be sending text, pdf, excel and word documents.

Any simple solutions?

I ended up using

http://www.simpopdf.com/pdf-creator-lite.html

to print to a file that allows users to create a PDF and to put a password in the print advance options.

It makes it simple and the user receiving the documents does not require anything but adobe reader.

PDF, Word, and excel have the feature to password protect a file.

just use win zip or win rar all free, and when you zip them select zip with password

so the only way the other party can open it , is with the password you created the zip file with

Note that WinRar and WinZip (while there are trial versions that are effectively free if you aren't fussy about the law) are commerical software.

I would suggest that you use you use www.7-zip.org instead. With 7z, you can

a) create a self extracting archive (so no software needed at all, you just run the SXE and it prompts for the password)

b) use AES@256 bit, the highest grade encryption available in any archiving product.

And its free :)

Some of the suggestions required to much involvement or download.  Simpo was easy and free.
