I've made OpenPGP keys using gpg 1.4.9.I have a public key and a sub key.And a passphrase.I can distribute the pub key. What is sub key? Can I distribute sub key?I think the phasephrase is the private key. Right ? (in the RSA Algorithm)?Where to use the Secure Shell Key? And why to distribute it?

The Modification Detection Code Packet is defined to use SHA-1, even though it does state in section 13.11. that this can be altered, and gives example methods. However this would cause interoperability, (q1)so I assume there is no standard method of doing this??
- How much of a threat do you believe this to be? Even though the SHA-1 hash is encrypted within the symmetrically encrypted integrity protected data packet.

View 2 Replies View RelatedI am trying to add a OpenPGP key for launchpad. It said to use this command.
Code:
gpg --fingerprint
When I use that command nothing shows.
Next I clicked on the the How to get the fingerprint. It said to go into Passwords and Encryption Keys. Then the My Personal Keys tab. I have nothing there. What should I do to get something there?

Importing an OpenPGP key
To import your OpenPGP key into Launchpad, you first need the key's fingerprint.
Note: You must ensure your key is in the Ubuntu keyserver before you try to add it to Launchpad.
Retrieving the key in Ubuntu
The easiest way to generate a new OpenPGP key in Ubuntu is to use the Passwords and Encryption Keys tool. If you are using Ubuntu 10.04 or an earlier version, it is located at Applications > Accessories > Passwords and Encryption Keys. In Ubuntu 10.10 and later versions, it is located at System > Preferences > Passwords and Encryption Keys.
Step 1 Open Passwords and Encryption Keys.
Step 2 Select the My Personal Keys tab, select your key and open the property window by pressing Space Bar or double clicking with your pointer. Select the Details tab of the property window.
Step 3 Select the Fingerprint text (the ten blocks of numbers and letter). Copy the text by pressing the Ctrl+c keys together.
Retrieving the key using the GPG command
Open a terminal and enter:
gpg --fingerprint
GPG will display a message similar to:
pub 1024D/12345678 2007-01-26
Key fingerprint = 0464 39CD 2486 190A 2C5A 0739 0E68 04DC 16E7 CB72
Geoffrey Hayes (My OpenPGP key) <geoffrey@bungle.com>
sub 2048g/ABCDEF12 2007-01-26
Highlight and copy only the numeric fingerprint: 0464 39CD 2486 190A 2C5A 0739 0E68 04DC 16E7 CB72 in the example above.
so i followed these instructions, and there was nothing in my "personal keys", same for the command. so my question is how do i get the fingerprint to be able to register my key in launchpad?
I'm having a problem installing Tor. I've installed it successfully a few times before thanks the excellent guide at: [URL] The error I'm having is when I request the gpg key:
Code:
ocean@ubuntu:~$ gpg --keyserver keys.gnupg.net --recv 886DDD89
gpg: requesting key 886DDD89 from hkp server keys.gnupg.net
Then after quite a delay all I get now (instead of "OK") is:
Code:
gpgkeys: HTTP fetch error 7: couldn't connect to host
gpg: no valid OpenPGP data found.
gpg: Total number processed: 0
I was just having some trouble getting an OpenPHP Key on Ubuntu Server. The link from Launchpad said, "go to applications..." but I'm not using a desktop environment, so I had to go to [URL] to learn how. Basically it boiled down to this:
Code:
gpg --cert-digest-algo=SHA256 --default-preference-list="h10 h8 h9 h11 s9 s8 s7 s3 z2 z3 z1 z0" --gen-key

I've been trying to find out which jabber/XMPP clients out there automatically sign messages with openpgp you send but documentation on that has been spotty. Could you tell me a. if you know any clients that can easily sign and encrypt all outgoing messages and b. should I worry if a client is only able to sign presence and not messages?
View 1 Replies View RelatedI am looking to be able to encrypt using OpenPGP certain outgoing emails on my linux server. Currently I have GPG setup with a public key, however encryption outgoing emails prooved to be harded.After a bit of research I have found GNU Anubis which acts as a middlemad between the MUA and the MTA, by encrypting emails before they reach my MTA (Sendmail)However I am having a bit of problem with the configuration of bind and remote-mta, as specified by anubis.I have the sendmail service running on port 25 and I want to leave it there, but I have configured my php.ini SMTP port to 24. So it runs through port 24 first and anubis then forwards the emails via remote-mta to port 25Here are my anubis configs:
bind localhost:24
local-mta /path/to/my/sendmail
remote-mta localhost:25
With all those set, I can't seem to get the basic modication of emails to work. (trying to change a certain subject to something else, just to see that anubis is working). However emails are still working with port 24 as the SMTP port.
I checked on clamav web site but no way to install it yet on Maverick.

I'm currently running OpenSuSE 11.3. I'm afraid as newer versions are released they will demand more of my old PC (Dell Optiplex GX270).

View 5 Replies View RelatedIn the wake of all of the stories about the Windows DLL hijacking bug, it appears that certain Linux distributions may be vulnerable to a similar problem related to the way that Linux handles a specific variable in some cases. The bug apparently was introduced via a Debian patch last year.The discussion on the possible bug in Linux began with a blog post by Tim Brown, a UK-based security researcher, who detailed a specific case in which Linux could be vulnerable to an attack similar to those designed to exploit the Windows DLL bug. The post spawned a related discussion on the Full-Disclosure mailing list, in which several others confirmed that they'd seen the problematic behavior in certain Linux distributions, including Fedora, Ubuntu and Debian.

View 5 Replies View RelatedI'm posting an E-Mail I sent to Pidgin Support, which didn't get answered. I'm doing this because I believe it is a general SSL problem. I've even tried a different chat client (Instantbird) - same error message. Since a week or so I'm not able to securely login to ICQ any longer with one of my accounts. Only if I disable "Use SLL" in the advanced settings, it works. With SSL I get the error message "Unable to connect to BOS server: SSL Handshake Failed". In the debug window the reason for the failure is "A record packet with illegal version was received". If I enable the setting "Use clientLogin", I get a different error: "Received invalid data on connection with server".
I get this error for all of my ICQ accounts if I enable this, but the other ones work just fine using only "Use SLL". I can login to the ICQ website with the "bad" account too, the settings are exactly the same for all 3 accounts. I was using Pidgin 2.7.3 when this happened first, upgraded to 2.7.5, but no change. I'm running RHEL 5.5 x86_64. I've attached the Pidgin debug messages for the "bad" case of the not working account and for the "good" case of one of the working accounts. I've tried a lot of things, like deleting the account and adding it again. I deleted the cached certificates. I changed the password on the ICQ website.
From the attachment I'm only pasting the most important part - the error message:
(20:27:14) gnutls: Starting handshake with bos.oscar.aol.com
(20:27:14) gnutls: Handshake failed. Error A record packet with illegal version was received.

(20:27:14) connection: Connection error on 0x9bf19f0 (reason: 0 description: Unable to connect to BOS server: SSL Handshake Failed)
I doesn't get into my head why 2 accounts work perfectly, but one doesn't. The login-server is exactly the same, so also the used certificate should be the same.

Which LXDE version of Linux has the newest version of Firefox and Open Office included?
I am looking for an iso file, and I am trying to run this off of a live CD for now. So I want a light version of Linux, probably LXDE, or if not, then probably XFCE. But I need a new version of Firefox and OpenOffice included.
Because, I tried burning the customizable NimbleX @ custom.nimblex.net . Pretty good, except it uses Firefox 2, and Open Office 2.3, which are outdated.
And I tried Mint XFCE, which might have been pretty good too, but it had some issue of blanking and requiring relogin after I opened hotmail frequently (user id: mint, password: blank).
The web browser and the word processing program are the most important and essential applications to me.
So are there any Linux versions in LXDE on LiveCD that include newer versions of Firefox (or at least another good browser) and Open Office (oo seems better than abi)? (Again, if no LXDE, perhaps XFCE?)
I just want to download a good version in an iso file, and burn it to a CD and get to work. Like I said the web browser and the word processing program are all important.
So really, what iso/LiveCD versions are the fastest for running on an older system, and yet have the newest browser and word processor included?
my laptop currently has 8GB of RAM and I wouldn't want that going to waste. I have read about the issues with flash on the 64 bit versions of buntu. Would you recommend going 64-bit or 32-bit with PAE? also, does the 10.10 kernel have PAE enabled by default?
