# kSecTrustRevocationValidUntilDate

A key whose value indicates the earliest date at which revocation information becomes stale.

```
let kSecTrustRevocationValidUntilDate: CFString
```

## Discussion

This key is only present if the [`kSecTrustRevocationChecked`](/documentation/Security/kSecTrustRevocationChecked) key has a value of <doc://com.apple.documentation/documentation/CoreFoundation/kCFBooleanTrue>. The value is a <doc://com.apple.documentation/documentation/CoreFoundation/CFDate> representing the earliest date at which the revocation information for one of the certificates in this chain might change.
