This is what I read on : PCworld with regards to PGP: PGP Freeware v6.5.8 Protect your e-mail messages from being intercepted and read by someone else This version also includes Self-Decrypting Archives (SDAs) which allow you to exchange information securely even with those who do not have PGP. I spent a lot of time trying to find out more about this sda feature but couldnt locate anything. Am I right in believing that I could send an encrypted email to someone who did not have PGP installed and they would be able to read it without problems ? (and this feature definetly works on v6.5.8?) Thanks!
