keymaster | Short term certificate based identity system | TLS library

I cannot connect to my coral devboard via mdt shell over OTG USB-C port after following along here. Initially, I had the mendel 'public device cowardly refusal' issue as outlined in an q&answer here. I used serial console and nmtui to get the devboard on my LAN and I fixed that checking code on my host to match my LAN arrangement (172 instead of 192 block) and that worked to start connection via mdt shell.

Now, when connecting I get the below error about only allowing a single ssh key. I have ONLY connected via screen in serial console since I initially flashed the board. No one has ever ssh'd.

I've created the following method that creates a KeyPair and logs the Certificate details:

I went to my profile settings and added a folder called 'chrome' and a file called userChrome.css.

I included this code:

How do I remove "url.com is now on full screen" message when I hover the top-middle portion of the browser?

I tried adding

I have the following step in my CircleCi setup to install Google Chrome:

I am trying to make an about page, I have text at the top and I want to have two images next to each other at the bottom, the problem I keep having is I can't figure out how to get them next to each other, they are at the bottom but they are on top of each other. I want them to be equal size both taking up 50% of the width of the Div box. I am a beginner at HTML and this is my first big project.

Here is my code

I'm currently creating a form of challenge-response authentication for a project I need for my Master thesis in computer science.

For this purpose, I need to create an RSA-PSS signature with a private key that is authenticated by a fingerprint so that it can only be used to create a signature when the owner of the device is physically present.

To achieve this, I use the Android KeyStore (backed by Keymaster/Gatekeeper in ARM TrustZone) to generate an RSA key pair (KEY_ALGORITHM_RSA) for use with the RSA-PSS signature algorithm (SIGNATURE_PADDING_RSA_PSS) for creating and verifying signatures (PURPOSE_SIGN | PURPOSE_VERIFY). I also require user authentication by setting the corresponding property to true.

Later, to create the signature over a buffer final byte[] message, I ...

1. obtain an instance of the FingerprintManager service
2. create an instance of the SHA512withRSA/PSS signature algorithm (Signature object)
3. initialize the Signature algorithm for signing with the private key (initSign(...))
4. wrap the Signature object into a CryptoObject
5. (perform some additional checks)
6. authenticate(...) the CryptoObject using the instance of FingerprintManager, passing (among others) a FingerprintManager.AuthenticationCallback to be called after the key has been authenticated by the user (by touching the fingerprint sensor on his/her device)

Inside the callback, use of the key is authenticated, so I ...

1. extract the Signature object from the CryptoObject wrapper again
2. use the update(...) method on the Signature object to stream the data to be signed (message) into the signature algorithm
3. use the sign() method on the Signature object to obtain the signature
4. encode that signature as Base64 and println(...) it out to StdErr so it appears in adb logcat

I created a sample code which is about as minimal as it gets.

I already read different post regarding python conversion from str to dic but I still have problems and I can't convert my str in dictionary.

this is my original string:
