perl pack and unpack commands
I have a file that contains user id and corresponding password. Lets say password is "help". The below command will create a hex value for string "help". perl -e 'print unpack "H*","help"' So now password is in encoded format. Then I decoded it in the script where am fetching the password. perl -e 'print pack "H*","77636462614e3031"' Now you help is required. In the second step when I am passing the hardcoded value, then it is able to decode it. But when I am using a variable it is not working. ex: var="77636462614e3031" perl -e 'print pack "H*",$var' This doesn't work. Let me know the syntax so that it will return correct value when I use it in a variable? I am trying to execute this perl commands in LINUX OS. Please help. |
