About the Encryption Circuit Padlock black filled icon

A closed padlock with a tall shackle and a keyhole sits at the center, and six circuit traces branch symmetrically from its left and right edges, each ending in a small node dot. The mix of lock and PCB lines says encrypted data in transit rather than a plain physical lock. It suits cybersecurity products, VPN and messaging apps, data privacy policies, cloud infrastructure diagrams and security conference slides.

Three traces per side step out at matching angles, giving the mark a wide, stable footprint that balances the vertical shackle. It pairs with shield, key and server icons in a security set. The node dots and keyhole compress below 32 px, so reserve this for headers, cards and hero areas.

This is the solid black filled version of the encryption circuit padlock icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.

It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
