I am interested in putting my application and its data in an encrypted partition. Are there any encrypted file system utilities that come with either the Linux kernel or OpenEmbedded? I could not locate any discussions in the kernel documentation or any openembedded recipes dealing with this. I'm currently using a stamp9g20evb with Linux 2.6.31. Thanks in advance!

Re: File system encryption
You need to add the crypto modules to the kernel, this is fairly easy.
Unfortunately the Angström distribution does not contain ready compiled user space tools like cryptsetup or the device-mapper you need. There are only two alternatives: You try to build cryptsetup (this will take the device-mapper as dependency in) with the OpenEmbedded framework, or you cross-compile it completely yourself.
