ecryptfs-utils - 111-6 main

eCryptfs is a POSIX-compliant enterprise-class stacked cryptographic
filesystem for Linux.
.
It provides advanced key management and policy features. eCryptfs stores
cryptographic metadata in the header of each file written, so that encrypted
files can be copied between hosts; the file will be decryptable with the
proper key, and there is no need to keep track of any additional information
aside from what is already in the encrypted file itself. Think of eCryptfs as
a sort of "gnupgfs".
.
eCryptfs is a native Linux filesystem. The kernel module component of
eCryptfs is part of the Linux kernel since 2.6.19.
.
This package contains the userland utilities.
