    A simple zero-config tool to make locally trusted development certificates with any names you'd like.

    Project mention: How to use Azurite for testing Azure Storage in dotnet? | | 2022-09-17

    Unfortunately, adding a certificate to the trust store requires a password prompt. On an Azure-hosted agent, this does not work and causes the agent to be stuck. To me, this could mean one of two things. Either the Azure team does not test over HTTPS, or they have a different set of test tooling. As it turns out, they have a set of helpers to construct the service clients and disable SSL verification. Like this:

    I see a lot of posts that say what is this worth, and I am always just checking open sea. So the easiest way is to figure out how to use metamask with your reddit account. If you are unfamiliar with metamask, there are some posts on how to use it in this and other avatar/NFT subs. The bottom line is to never give out your seed phrase to anyone and make sure you get metamask from the source.
