At times, you may want to identify potential keywords that could reveal a pattern in a code.
As an example, consider the code:
te68o5erezim2tk8uf
To locate a possible keyword, the regular expression to use would be:
^[te68o5erezim2tk8uf]{8}$
Here, the ^
and $
signify the start and end of the string, i.e., a complete word.
The [te68o5erezim2tk8uf]
indicates that the search should be for a character present within the []
.
Lastly, the {8}
specifies that the search should look for 8 of those characters. Since the prefix and suffix each occupy 5 characters, the remaining eight characters form the keyword.
