Passwords can be categorized into various types based on their composition. Let us take a look at these types to enhance our understanding of password cracking. |
-
Passwords that contain only letters: As rightly inferred, these contain just alphabets and are the easiest to crack. Example: "secret"
-
Passwords that contain only numbers: These passwords consist purely of numerals. Example: "12354"
-
Passwords that contain only special characters: These passwords consist of only special characters. They are easy to crack in accordance with their decreasing length. Example: "*%$%@"
-
Passwords that contain letters and numbers: These passwords were the first step towards secure passwords. They are relatively harder to crack than passwords with just letters or numerals. Examples: "a3rf5"
-
Passwords that contain only letters and special characters and passwords that contain only special characters and numbers are quite similar to the preceding one. Examples: "df%g$i", "39*&4"
-
Passwords that contain letters, special characters and numbers are considered to be the most secure as the combination can be difficult to crack. Given an appropriate length, they can be considered to be safe and if encrypted well, safe on the network as well. Example: "a#d5y8%"
