Hello, I did buy version IV in 2010. I did not use it very much that time, but when I wanted to download it again to give it another try, I realized that I could not download the version that works with my license (4), but only the last version 5.
I did email support for a download link, but they told me they 'don't supply old version of software'. They did offer me an upgrade price.
Just wanted to point out, that the upgrades are mandatory with this application. Unless you keep a backup I guess.. which was not my case. It may be every couple of years, but still is something to keep in mind.
If Apple Mail encryption feature with certificates does not suit your needs, this may be a nice alternative.

No. R10Cipher is a commercial product, not Open Source.
The Trial Version can be tested as much as you like to ensure integrity and security.

On sale at MacZot today for $8. Don't really know if I need this or not, and if I do, how to use it. Please put videos on your site showing persons like myself who aren't familiar w/ this how to use it. Downloaded your pdfs on R10 (42p manual, 7p product info, and 15p why R10cipher). Too much to read and learn about to make a decision in less than a day (to get the $8 price offered today only). So if i buy it today at MacZot for $8 to run on my PPC PowerBook G4 then I can also run it (free upgrade or not?) on Lion when I buy a new MacBook Pro? What is your upgrade policy? I see in your manual that you state, "Note: R10Cipher IV needs a different serial number to Versions 1.x., 2.x and 3.x Existing users can upgrade at reduced cost. Please contact upgrade@artenscience.co.uk for further details." What would that "reduced cost" be? Thanks.

Upgrade to version 5 with a 50% discount for existing users if purchased before 22nd July 2012, Midnight GMT.

We now include a PowerPC build as standard again for those with older computers.

One license covers installation on two computers.

Good tip on the videos, it'll happen in the next few days.

Ref: Recipient, Decryption Only

From the FAQ on the Site:

Have You Got a Free Version for Decryption Only ?
We used to provide R10Decrypt for this purpose. However with the goal of decreasing the maintenance overhead and making it easier for 'Decrypt Only' customers to upgrade to the full version, you can now use the standard R10Cipher Trial version for this purpose. To remove the Nag Screen and Overlay / Trial Version window, just enter the User Name 'Decrypt Only' into the Preferences window and clear the Serial field. Save the Preferences.
