About the Binary Lock Circle color filled icon
A closed padlock with a rounded shackle and a keyhole sits beside three rows of binary digits (01011, 110, 01, 11) cascading down the left, all held inside a thin circular frame. Together they read as encrypted data, cryptography and protected credentials. Use it on cybersecurity landing pages, VPN and password manager apps, developer documentation about hashing, data privacy settings screens, and IT security slide decks.
The padlock body is a wide rounded rectangle balanced against the staggered number rows, so the composition fills the circle evenly without crowding. It pairs naturally with shield, key, fingerprint and firewall icons in the same circular outline family. At small sizes the digits blur together, so keep it at 48 px or larger where the binary detail carries the meaning.
This is the colour filled version of the binary lock circle icon: a flat, solid-colour shape that stands out in dashboards, marketing pages and app tiles where the icon needs to carry colour meaning.
