Third Party Tools
Although Windows 95, 98 and NT (as well as installations of Windows 2000 and XP that do not use NTFS) do not support EFS, third party tools are available to encrypt files for secure storage and transmission. The most well known tool is Pretty Good Privacy or PGP for short. PGP generates a unique public and private key for each user, and uses these keys for asymmetric encryption. The mechanics of this are far outside the scope of both this book and the A+ exam, and it is sufficient to be aware that PGP is considered secure. However, outside of the A+ exams Security and Encryption is an important and growing issue, which every user or administrator should have an interest in.
