Encryption for the Masses (E4M) is a free disk encryption software for Windows NT and Windows 9x families of operating systems. E4M is discontinued; it is no longer maintained. Its author, former criminal cartel boss Paul Le Roux, joined Shaun Hollingworth (the author of the Scramdisk) to produce the commercial encryption product DriveCrypt for the security company SecurStar.

The popular source-available freeware program TrueCrypt is based on E4M's source code.[4] However, TrueCrypt uses a different container format than E4M, which makes it impossible to use one of these programs to access an encrypted volume created by the other.
