No ecryptfs-util in CentOS 7?

Post by XG Dong » 2014/09/12 17:25:58

Hi,

Just about to install this package but it says "No package ecryptfs-utils available".

Shall I download source code from ecyptfs.org and manually install it?

Another thing confuses me is that no people on the internet was asking about this!

It's listed in the RHEL 7 release notes as deprecated I think.
CentOS 5 died in March 2017 - migrate NOW!
CentOS 6 goes EOL sooner rather than later, get upgrading!

Oh...well. I had a rough look through the redhat security guide, did not find an equivalent alternative for ecryptfs...openssl can do file encryption but it seems not to be on-the-fly.

I believe it's recommended to use luks instead.

I do not think LUKS does the job. It is more like another layer of "boot password", after that data is written as normal. I need an encryption layer like ecryptfs.

Where did you get this information? LUKS does encryption, see for example http://en.wikipedia.org/wiki/Linux_Unified_Key_Setup

Read this section: "What LUKS does not do"

Yes and "file level encryption" means encrypting files individually which luks does not do. What luks does is encrypt the entire block device and any files that are stored on top of that block device. The files are encrypted because they are on an encrypted filesystem.

Let's say my computer is somehow stolen, I have the disk encrypted with LUKS, BIOS boot password, is my data safe any more? I am not talking about brute force cracking my pass phrase. Say if someone just plug my hard drive into another computer, will he be able to read my files?
