bind a certificate

netsh http add sslcert ipport=<ipAddress>:<port> ^
    certhash={<certificateThumbprint>} appid={<someGuid>}

check current bindings

# all
netsh http show sslcert
# single ip/port
netsh http show sslcert ipport=<ipAddress>:<port>

remove binding

netsh http delete sslcert ipport=<ipAddress>:<port>

errors

When attempting to bind, the following error might occur;

A specified logon session does not exist. It may already have been terminated.

This means a private key needs to be attached to the certificate prior to binding.

Add certificate authority

Via administrator session

certutil -addstore "CA" .\SomeCertAuthority.pem

Add -f to force replace if the cert already exists

Create a certificate

openssl req -newkey rsa:2048 -new -nodes -x509 -days 3650 -keyout ~/git/key.pem -out ~/git/cert.pem

Current directory:

npx http-server -S --cors -C ~/git/cert.pem -K ~/git/key.pem -o --port 3001

A specific directory:

npx http-server my-directory -S --cors -C ~/git/cert.pem -K ~/git/key.pem -o --port 3001

1. Download the certificate authority certificate: myCA.pem
2. Tap install
3. Settings > General > Device Managemnet > Install the cert
4. Settings > General > About > Certificate Trust Settings > Enable the cert
