If we look further down the UTF-8 table we can see where the ASCII set ends and other characters start. If we select hex as the display format on the UTF-8 page we can see that all ASCII characters are represented in the same way as in the ASCII table. To understand this better, let us compare the UTF-8 table and the ASCII table with each other. The bytes is what matters since this is what Hashcat uses. This gives us the same encoded byte values for the same character no matter if we use ASCII or UTF-8. (In other words, ASCII and the first 128 characters in UTF-8 have a direct one-to-one mapping). The first 128 bit combinations (from 0000 0000 to 0111 1111 ) are reserved for the ASCII characters. It uses one to four bytes (from 0000 0000 to 1111 0111 1011 1111 1011 1111 1011 1111 ) and was designed to be backward compatible with ASCII. One such way to encode characters and symbols is the UTF-8 encoding. To encode all possible characters we must use several bytes, much like we can encode numbers bigger than 9 using several digits. It consists of 128 characters/symbols which are encoded from 0000 0000 to 0111 1111 in binary.Ī single byte can only encode 256 values, but this is often not enough.

In this article, I describe how to create mask files for Hashcat with a UTF-8 multibyte character set.ĪSCII is the original character encoding schema for Latin/English characters.

These characters are slightly different from the normal ASCII table and a bit trickier for a password cracking application like Hashcat to understand. People in Europe tend to use passwords that include the local language special characters. With this information, we can make some analysis and recommendations for the customer. The other part is to make something usable of the hashes by cracking them and get the passwords in clear text. When we test the security of a network, we often achieve access to hashed credentials of users of that organization.īut getting the hashes is only half the fun. What they all have in common is that they all have users - and users tend to have passwords in some variants. In the line of my work as a penetration tester, I get the opportunity to test the security of a lot of different customer systems.
