This post introduces a solution for automatically setting up and tearing down shell environments for PowerShell in Windows. It is proposed as a potential alternative to the bash-based tool direnv, which, while effective at loading .envrc files in the current or nearest ancestor directory, has limited compatibility with PowerShell in Windows.
JoyID is a multichain, cross-platform, passwordless and mnemonic-free wallet solution based on FIDO WebAuthn protocol and Nervos CKB. This post shows how to verify the signature from the method signChallenge of the @joyid/ckb package. The method reference page has a demo. I use the demo to obtain an example response then verify the response using the OpenSSL command line and the Python library PyCryptodome. The JoyID follows the WebAuthn specification and employs secp256r1 for signing. Although the guide references section 6.3.3 of the WebAuthn specification, titled “The authenticatorGetAssertion Operation”, I discovered that the example in this repository provided me much more helps.

Cartograph is a handsome monospaced font family featuring lush italics, code-friendly ligatures It’s funny to see those handwriting like italic characters while coding, so I purchased the font and integrated it into my tools.
As mentioned in ♯ Yubico for Windows, I used PuTTY/Plink instead of the OpenSSH client together with YubiKey because the OpenSSH Client does not support the socket file created by GnuPG. Plink does not work well in Windows Terminal. The Visual Studio Code SSH Remote does not support Plink as well, because it will pass some command line arguments that are not supported by Plink. So I decide to switch back to the OpenSSH client. Fortunately, the utility wsl-ssh-pageant can create a tunnel between a Windows pipe and the pageant socket, and the OpenSSH client can use the Windows pipe as SSH_AUTH_SOCK. This article is a tutorial to set up wsl-ssh-pageant.
