Nother way to put files and folders into a single encrypted and compressed package. An SDA is slightly larger in size than a PGP Zip archive because the executable file is included in the archive, but this means that the SDA can be opened on Windows systems that don't have PGP Desktop installed. SDAs can only be protected by passphrases, so you have to find a secure way to communicate the passphrase of the SDA to the intended recipient.

If you have files, directories, or even entire drives on your system that you want to securely send to someone who doesn't have PGP Desktop installed, you can create a self-decrypting archive (SDA) of the data. An SDA is compressed, but the included executable makes it slightly larger than a PGP Zip archive would be with the same content. SDAs can only be opened on the same operating system as they were created on; so if you create an SDA on a Windows system, it can only be opened on another Windows system.
