One-liner to remove eMudhra from trust chain:

Mac OS

sudo security find-certificate -c "eMudhra" -p /Library/Keychains/System.keychain > /tmp/emudhra.pem && sudo security add-trusted-cert -d -r deny -k /Library/Keychains/System.keychain /tmp/emudhra.pem

Ubuntu Linux

sudo sed -i '/eMudhra/s/^/!/' /etc/ca-certificates.conf && sudo update-ca-certificates --fresh

Windows Powershell

Get-ChildItem -Path Cert:\LocalMachine\Root, Cert:\LocalMachine\CA | Where-Object { $_.Subject -like "eMudhra" } | ForEach-Object { Move-Item -Path $_.PSPath -Destination Cert:\LocalMachine\Disallowed -Force }

Windows cmd

certutil -store CA "eMudhra" | findstr "Serial" > nul && certutil -exportstore CA "eMudhra" %temp%\emudhra.p7b && certutil -addstore -f "Disallowed" %temp%\emudhra.p7b
