ecryptfs-manager doesn't work correctly

[Jason Xing]

Hi,
i'm using Ubuntu15.10 Desktop. (A few days ago, i was trying to use Ubuntu 12.04, 14.04). There's still one problem i couldn't solve for a while.
I can't use the openssl for ecryptfs.
I create a public/private keypair for ecryptfs using ecryptfs-manager. But there is nothing to select.
Sorta like this:
jasonxin@jasonxin ~ $ ecryptfs-manager

eCryptfs key management menu
-------------------------------
    1. Add passphrase key to keyring
    2. Add public key to keyring
    3. Generate new public/private keypair
    4. Exit

Make selection: 3
Select key type to use for newly created files:
Selection:

There should at least one option for me to select, sorta like this:

Make selection: 3
Select key type to use for newly created files:
    1. OpenSSL
    2. Probably some other option here
Selection:

AND

$ sudo mount -t ecryptfs ~/temp ~/temp
[sudo] password for jasonxin:
Select key type to use for newly created files:
    1) openssl
    2) passphrase
    3) tspi
Selection:

But i've got like this:

$ sudo mount -t ecryptfs ~/temp ~/temp
[sudo] password for jasonxin:
Passphrase:

So i'm confused about that. Am i missing something in installing ecryptfs-utils( i use my friends' computers for ecryptfs. Unfortunately ,the same questions happen over and over again. ).

Ubuntu doesn't ship the OpenSSL key module because it performs poorly and does not receive adequate testing.

You can build the OpenSSL key module from the upstream source yourself if you'd like to use/test it.
