**Decryption Time** ![image](https://forum.kee.pm/uploads/default/original/1X/11b282464d0e8ad1aeee675503361efe35411d5f.png) What’s the recommendation for **decryption time** , and what should I be concerned about it when choosing X Speed vs Y Speed. And Is there any danger for higher speeds depending of my machine hardware? **Database Format** ![image](https://forum.kee.pm/uploads/default/original/1X/d87d4699e638b67fcc65eeee1d435d861832c259.png) Should I be concerned about about database formats when using a password manager, and why? **Key Derivation Function** ![image](https://forum.kee.pm/uploads/default/original/1X/0f6dc77612a11b44f60b5b6596667a7524db53e2.png) What is exactly the **key derivation function** , and what it does? **Transform rounds, memory usage and Parallellism** ![image](https://forum.kee.pm/uploads/default/original/1X/b5466a794d78ef6462fb230f9aa9e1b10659fadd.png) What they does? (except by memory usage), and why is it matter to have a choice to choose how many memory usage in this case, what’s the difference? **Security Key File** ![image](https://forum.kee.pm/uploads/default/original/1X/4fd95a120f4e8bac2568197b344c5c1f16c8eb89.png) Which one is the best, why and what should I be concerned about it. _I formated the topic to make it easily to someone who have the same doubts to learn about it either. I appreciate everyone’s time whose answer the topic._
