Encrypt your files transparently in Linux with eCryptfs, an enterprise-class stacked cryptographic file system.

f you need to share data in a Linux environment, some basic encryption solutions and practices will allow you to do so in a very secure manner. Many tools enable data encryption in Linux, and each has its pros and cons. Yet many developers try to build their own cryptographic technology, which often gets them in trouble. A better approach is to employ tools that rely on proven cryptography techniques and algorithms. A great example of this approach is eCryptfs, a complete cryptographic file system for Linux that essentially is a robust implementation of mature cryptographic technology.
eCryptfs, which is embedded inside the Linux kernel, is a stackable solution for single-file encrypting. Stackable means that eCryptfs is a layer that works on top of other standard, lower file systems, such as ext3, FAT, FS, XFS, ReiserFS, and (since kernel version 2.6.24.X) NFS. eCryptfs delivers its encryption solution by using relevant existing kernel services such as keyring management.
