echo -n test | md5And the output is a simple hash:
098f6bcd4621d373cade4e832627b4f6The reason I use the -n is because if you just echo without it the new line is included. You can also use the -s option of md5 without echoing anything:
md5 -s "test"Which outputs:
MD5 ("test") = 098f6bcd4621d373cade4e832627b4f6If you then pop this unreversible hash into some tables of hashes or even sites that just do such things for you these days, you can basically reverse them pretty easily now:
curl http://md5.gromweb.com/?md5=098f6bcd4621d373cade4e832627b4f6 | grep "The MD5 hash"Now use something stronger. Something with numbers, letters, special characters, etc to make a hash. The resultant lookup is likely going to be empty when you attempt to reverse the hash. Therefore, to see if your password is easily reversed from the MySQL md5 tables of all those websites you put it into, convert it to a hash and then pop it into a reverse site.
echo -n noice
