Obtain the hash technique in user. MYD in MySQL

During server elevation, especially in windows, we find that the permission is not high, but we can read the mysql datadir directory and download the user. MYD file successfully. However, when reading the content, the root password hash is often incomplete, and there is no mysql environment at hand or an import error .. you can try the following methods

First, look at the figure above and find the root hash ciphertext:

* ABFA954DFEEF60FFF0B14 21-bit F2DF23A6B00 11-bit

The preceding "*" indicates 40-bit encryption.
List all ciphertext hash entries

* ABFA954DFEEF60FFF0B14 21 bits

F2DF23A6B00 11 bits

* 5AED70200C381D1E57E5F58FA0A9C 29-bit

C93E64907C9070B076156E5 21-bit

Obviously, the 29-bit root password and 11-bit password are the complete 40-bit password.

* 5AED70200C381D1E57E5F58FA0A9C + F2DF23A6B00 40 BITs
