Where and when are cryptographic algorithms used (During Boot , Playing games, typing, Internet
All of them ?
I`m trying to understand the need for TPM 2.0
It`s another one of those thing`s that everybody say`s you have and got to have (Like the King's new clothes story, the Dressmaker say's you have clothes king, but alot of people did not see anything)
And the other one where your computers multitasks (for 1 year then slows down because to many things are locking it up after a year) as long as you don't install more than anything more than the operating system with no driver`s
sorry don't mean any disrespect to anybody i am not being a smarta**.
but ive been playing with computer's since a 386sx 25mhz.
And they have always left me with a loss of everything :)
Explanation for TPM 2.0 for the working man ? other than it's more secure
I've read that it is more unsecure

To my knowledge and experience:
During boot: yes - e.g. Secure Boot uses cryptographic signatures to verify that the system firmware and OS have not been tampered with. Or Disk encryption (e.g., BitLocker, LUKS) ensures data confidentiality before unlocking the drive.Playing games: probably only if its online
Typing: Some wireless keyboards might use encryption, but not always
Internet: Yes, everything you connect to via https uses encryption (TLS) and there are cryptographic algorithms to secure authentication (password hashing, two-factor authentication)
I don't know that much about the TPM 2.0, but in most of the cases new versions offer support for newer algorithms and have a more secured/improved architecture. Over the years, cryptographic algorithms need to generate longer keys to maintain their security, because the computing power in general is improving so fast. And there are new algorithms like ECDSA which are in general more efficient to save time.
But ofc new things might have vulnerabilities, especially in the beginning. Nevertheless I would say they are necessary.
