Hi, all. So, in reviewing my OpenSSH keypairs and evaluating the size my RSA keys should be, i realized that, if i update my 2048-bit keypairs to 4096 bits, it really doesn't matter that much, because they're still only encrypted with 3DES, which provides an effective 112 bits of symmetric encryption strength: $ head -4 ~/.ssh/id_rsa -----BEGIN RSA PRIVATE KEY----- Proc-Type:

In our app, users give us sensitive information (credentials for logging into a third party site). At some point, we need those credentials in cleartext in order to access the third party site, but while they''re in our database, we want to make best effort for protecting them. What techniques have people used for this? I find myself asking "WWMD (What Would Mint.com Do?) -- any

From RHEL docs: "The default implementation of LUKS in Red Hat Enterprise Linux is AES 128 with a SHA256 hashing. Ciphers that are available are: AES - Advanced Encryption Standard - FIPS PUB 197 Twofish (A 128-bit Block Cipher) Serpent cast5 - RFC 2144 cast6 - RFC 2612" My question is: What will be the performance impact on my Celeron 1.73 GHz CPU and/or hdd

Anyone know of a good (fast) way to encrypt/decrypt uploaded files in RoR? I''ve seen this project: http://ezcrypto.rubyforge.org/ but it only seems to encrypt strings and such. I need to encrypt files once they are uploaded, then decrypt them when they request the file back. Any ideas? Thanks, Mark -- Posted via http://www.ruby-forum.com/.

First, I have what I consider to be decent experience with SSH, and have been running VanDyke's VShell SSH server for considerable time under Windows 2000/XP. Recently, I have been working with Mac OS X and FreeBSD and have been using OpenSSH 3.4p1 The sftp server seems to have major issues when serving files, specifically, if one data stream is used the transfer rates fluxuate between 80 and

I just upgraded my Windows SSH client from the 2.1.x version (whatever it was) to 2.2.0 and am now experiencing difficulties connecting to my OpenSSH-2.1.1p1 Linux servers. I'm not as up-to-speed as I should be on the inner workings of the handshakes that go on, but from the debug logs and from trying different connection methods, it seems to be isolated to using publickeys. This

After upgrading to openssh-3.4p1, password authentication is no longer working on my system. I'm running Linux RedHat 6.2 with: kernel 2.2.20 openssh-3.4p1 openssl-0.9.6 pam-0.72-6 pwdb-0.61-0 I've tried it with and without compression, with and without priv sep, and I always get errors like this: Jun 30 19:07:48 sugarfreejazz sshd[1344]: Failed password for randy from 10.10.10.2 port

Hi, The following discussion was posted to comp.security.ssh however, it seems that my problems may be a bug in SSH. Could someone please indicate whether there is a bug fix, or perhaps whether I should go back a version or so. In summary: - Win98 machine (client) - OpenSSH as packaged with Cygwin tools 1.1.8 (openssh-2.5.2p2-3) - Connecting to a Sun running Solaris. ssh: SSH Secure Shell

I use a solution to crypt a string that I found using OpenSSL. But the crypted string becomes very long, too long for a varchar 255 to hold it. What can I do to make it shorter? Or should I just use text as column in the mysql db? public_key_file = ''lib/public.pem'' public_key = OpenSSL::PKey::RSA.new(File.read(public_key_file)) @encrypted_string =

Hi list, I'm building a backup server for 3 hosts (1 workstation, 2 server). I will use bacula to perform backups. The backup is performed on disks (2 x 3TB on mdraid mirror) and for each hosts I've created a logical volume with related size. This 3 hosts have different data size with different disk change rate. Each host must have a limited sized resource and a reserved space. If a

Hello, I am having a very aggrivating problem, and I will try and provide all of the necessary information. I have openssh-3.7.1p2 with openssl-0.9.6k installed on Solaris 8. Here is what I've been able to determine so far: 1. Local account authentication works fine (non-NIS+). 1a. NIS+ is running at security level 2 2. Telnet authentication works fine. 2a. When I use the SSH client,

I sent in a patch a week or so ago for a problem a customer of mine was seeing when trying to connect to their OpenVMS system with an 3.8.1p2 OpenSSH client (running on a linux box or in cygwin) and trying to login to an account who had an expired password. The problem continues although now it has nothing to do with what my patch handled as they have since upgraded their SSH software on the VMS

Hi, I just installed openSSH2.1.0 an a linux system and tried to connect to a server running an SSH2 server. Unfortunately I wasn't able to connect because of a signature error. I am connecting to the host for the first time. Does anybody know, why I have this problem and why I can't connect? Thanks, Stefan Mangard Here is the debug output: [smang at grad1 bin]$ ssh -2 -v

First off, I am not a subscriber, so please CC replies to my email address. The problem I am having -- I do not know who is to blame, but am just covering all angles. I run OpenSSH 2.1.1 on FreeBSD.
