About the Keyhole black filled icon
A single keyhole is drawn in the traditional old-lock shape: a large circular opening at the top flowing into a tapered slot whose sides splay outward to a flat bottom edge. It stands for security, restricted access, privacy and unlocking. Good for login and password screens, encryption and VPN product pages, privacy policy sections, hotel or real-estate apps, and escape-room or mystery branding.
The form is a single continuous outline with the circle occupying the top half and the trapezoid slot the bottom, giving a strong vertical silhouette that stays readable at tiny sizes. Pair it with padlock, key and shield icons for a consistent security set. It also works well reversed out of a solid colored button.
This is the solid black filled version of the keyhole icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
