# kSecAttrApplicationLabel

A key whose value indicates the item’s application label.

## Declaration

```swift
let kSecAttrApplicationLabel: CFString
```

## Discussion

Discussion The corresponding value is of type CFData and contains a label for this item. This attribute is different from the kSecAttrLabel attribute, which is intended to be human-readable. Instead, this attribute is used to look up a key programmatically; in particular, for keys of class kSecAttrKeyClassPublic and kSecAttrKeyClassPrivate, the value of this attribute is the hash of the public key.
