# considerExpiration

Consider expired certificates invalid.

## Declaration

```swift
static var considerExpiration: SecCSFlags { get }
```

## Discussion

Discussion When passed to a function that performs code validation, this flag requests that code signatures made by expired certificates be rejected. By default, expiration of participating certificates is not automatic grounds for rejection.
