Using Cryptographic Hashes to verify file download integrity

Using Cryptographic Hashes to verify file download integrity

NOTE: Don’t use MD5 (see below)

The SHA hash functions are a set of cryptographic hash functions designed by the National Security Agency (NSA) and published by the NIST as a U.S. Federal Information Processing Standard. SHA stands for Secure Hash Algorithm.

Vendors provide a sha-1 hash for software downloads. This enables you to verify that your downloaded files are unaltered from the original.

To confirm file integrity, use an sha-1 utility on your computer to calculate your own hash for files downloaded from the VMware web site.

If your calculated hash matches the message digest we provide, you are assured that the file was downloaded intact.

sha-1 utilities are available for Windows and Linux and Mac. Most UNIX installations provide a sha1sum command for sha-1 hashes. You may need a newer linux kernel to calculate the checksums for larger files.

Windows:

The File Checksum Integrity Verifier (FCIV) can be used on Windows based products to verify sha-1 values.

See: http://support.microsoft.com/kb/841290 for details on FCIV.

> fciv -sha1 test-file.exe

// File Checksum Integrity Verifier version 2.05.

Mac OS X: How to Verify a SHA-1 Digest http://support.apple.com/kb/HT1652

Instructions on checking an sha-1 checksum on a Mac:
In Finder, browse to /Applications/Utilities.
Double-click on the Terminal icon. A Terminal window will appear.
In the Terminal window, type: “openssl sha1 ” (sha1 followed by a space).
Drag the downloaded file from the Finder into the Terminal window.
Click in the Terminal window, press the Return key, and compare the checksum displayed to the screen to the one on the vendor’s download page.

About MD5

MD5 was designed by Ron Rivest in 1991 to replace an earlier hash function, MD4. In 1996, a flaw was found with the design of MD5. While it was not a clearly fatal weakness, cryptographers began recommending the use of other algorithms, such as SHA-1 (which has since been found also to be vulnerable). In 2004, more serious flaws were discovered, making further use of the algorithm for security purposes questionable; specifically, a group of researchers described how to create a pair of files that share the same MD5 checksum. Further advances were made in breaking MD5 in 2005, 2006, and 2007. In an attack on MD5 published in December 2008, a group of researchers used this technique to fake SSL certificate validity.

US-CERT says MD5 “should be considered cryptographically broken and unsuitable for further use,”and most U.S. government applications now require the SHA-2 family of hash functions.

It’s amazing! DisplayPort to the new Asus PB287Q 4k display is truly 4 times the resolution of the old 1080p HMDI.

I just added my 3rd 1080HD screen so now there are 6 times the standard desktop space of just 1 screen.

Get yours now - in stock at your local Central Computer store. 

Plugs right into the displayport on your PC. Works at 3840 by 2160 and 30 Hz with the AMD Radeon 5800 series card and I’m still able to drive total of 3 displays - DP, HDMI, and DVI.

Using Red Hat RDO PackStack to build #OpenStack #Neutron

Many people using OpenStack will start off with Devstack running in a VM on a laptop to get a feel for what is possible but when running VMs or playing around with networking and storage options and running nova to different hypervisors is needed it’s time to install a “real” openstack distribution.  You can build openstack from scratch using the manual installation steps which takes hours but is an excellent learning experience or you can use one of the assisted installation distribution methods.

Red Hat is the leader in the Enterprise Linux space. They make RHEL, CentOS, and Fedora and output code which is used by many other distributions.

Suse, Debian, Canonical Ubuntu and other distros are gaining in popularity and striving to differentiate themselves in the market.

Packstack is a CLI tool created by RedHat employee http://goodsquishy.com/ that uses puppet to script the installation and configuration of OpenStack components on a redhat based operating system.

RedHat started RDO with community-supported packages of the most up-to-date OpenStack releases available for download. They also offer enterprise-level support with the Red Hat Enterprise Linux OpenStack Platform.

To get started with RedHat RDO and install OpenStack in 15 minutes you need a machine with a running OS already.  Open a root shell and a web browser and head over here and follow the 3 simple steps to get setup.

http://openstack.redhat.com/Quickstart

This will get you up and running quickly.  What is great is that an answer file is created which can be edited and reused as more sophisticated configurations are needed. So it’s a great place to start but also offers many sophisticated options under the hood.

Here’s a list of questions you might like to explore:

Text or Binary - Using Bitbucket with PowerShell and PowerGUI

How to setup Dell Quest PowerGUI to edit PowerShell PS1 scripts to Bitbucket with the correct UTF-8 Text encoding to overcome the erroneous Binary Encoding

We use the following workflow to update Microsoft PowerShell (VMware PowerCLI actually) scripts in the Atlassian Bitbucket GIT repository and had this same issue when getting started out of the box with defaults.

Workflow

The default files created with PowerGui are having the 3 letter file name extension ps1 but when uploaded with Sourcetree they show up in Bitbucket as Binary so text features like edit or diff don’t work. Based on the feedback here and with other google searches the fix for this was to indeed change the encoding to UTF-8, make a simple change to the file, and upload it again. After a few tries this works perfectly and is repeatable. There is a trick though as PowerGUI doesn’t make it obvious how to change the encoding. Here are the steps.

Procedure

  1. Start powergui as you normally would. BTW – this is a windows program and I’ve tested this on Windows 8
  2. Choose “PowerShell Libraries” from the File menu
  3. Check the box to enable “Add-on.ScriptEditorEssentials” from the Snapins/Modules dialog box. Click OK.
  4. Now Enable UTF-8 Encoding from the File menu.
  5. That’s it. Any file you save now will be UTF-8 encoded and show up properly in Bitbucket once uploaded.
