This Unlock icon is a responsive icon. This means that it's optimized for four resolutions, from tiny 16x16 until highly detailed 80x80. The style comes from the latest Microsoft Office, which makes it perfect for any Windows applications, in particular, those with ribbon toolbar control. Unlike other icon packs that have merely hundreds of icons, this monster icon pack contains 15,300 icons, all in the same style and quality.
It's an icon of a lock. There is a circle to represent the lock mechanism, with a small black circle with a rectangle extending from the bottom to represent the keyhole. A curved line extends from the top left of the large circle, and arches almost all the way to the right, to represent an open lock.
