Great tool to hash string right away! :) David Hi guys,
I know this is a post about cracking md5, but for some of you looking for a tool to hash, I’m using this online md5 encoder to hash string.
Great tool to hash string right away! :)

Step 1. Download the source: wget ftp://ftp.openwall.com/pub/projects/john/1.7.2/john-1.7.2.tar.bz2 Step 2. Unpack the source: tar jxvf john-1.7.2.tar.bz2 Step 3. Change directory into the directory which was created: cd john-1.7.2 Step 4. Download the patch: wget ftp://ftp.openwall.com/pub/projects/john/contrib/john-1.6.37-raw-md5-1.diff.gz Step 5. Unpack the patch: gunzip john-1.6.37-raw-md5-1.diff.gz Step 6. Apply the patch: patch -p1 john-1.6.37-raw-md5-1.diff.gz Step 7. Change directory into src: cd src Step 8. Compile for your arch (run "make" to see a full list on targets): make generic If you can't find a file, browse the FTP site. If you're having trouble with decompressing or patching, read the manual. If the build fails (step 8) it's probably something with the code check Google. Keep in mind that the version number may vary depending on what version you have…

I usually go about cracking hashes in this order: 1. Online crackers like www.netmd5crack.com 2. Wordlist attacks using something like cain and able 3. Rainbow tables - google rcracki 4. Brute force Knowing how to use john is always good because it is fast. Good writeup.

I have been trying for a couple of days now and could not break it. Looks like we need to have a # before the hex code. Thanks a lot for that.
