Lock icons SVG — locked, unlocked, permissions and encryption
Search term: 锁、解锁、安全、权限、加密、隐私 — every asset is free to download as SVG or convert to PNG
A lock only works as a pair of states: locked and unlocked have to be distinguishable at a glance, and not by colour alone. Plenty of icon libraries draw these two shapes so similarly that they become identical at 16px and the user is left guessing.
Where to use it
- Sign-in and account security

Picking and recolouring
Check the shackle: an open shackle reads as unlocked, a closed one as locked — colour is only a secondary cue. Don't mix shields and locks in the same interface: a shield means “protected”, a lock means “locked”, and those are different promises.
