Simple shell script to break ceaser cypher:
Say we have a alphanumeric cyphered using Rot13 :
Eg:
5Gr8L4qetPEsPk8htqjhRK8XSP6x2RHh
In order to break this, all we need is a simple tr construct
$ echo 5Gr8L4qetPEsPk8htqjhRK8XSP6x2RHh | tr 'N-Z' 'A-M' | tr 'A-M' 'N-Z' | tr 'n-z' 'a-m' | tr 'a-m' 'n-z'
This will give u the decyphered stuff.
