Analysis of task parola

The idea of the task is to create a password which satisfies given requirements. 
The intuitive solution, and in fact the one giving full points, is to compose a password and change it until all the conditions are satisfied. 
The observation here is that when a given condition is satisfied, another one may stop being satisfied. 
For example, when adding the best move, namely Nf7+, the sum of the digits in the password becomes 32 and a previous part of the password has to be changed.

Two other intuitive solutions for partial points are also shared.

For those interested, the knight cannot be taken, because the black king is in check from the queen and the knight, and after the only move Kg8 follows Nh6#, the knight covers f7, and the queen g7, h8.
