A key whose value is a Boolean that indicates whether the cryptographic key can be used for decryption.

```
let kSecAttrCanDecrypt: CFString
```

## Discussion

The corresponding value is of type <doc://com.apple.documentation/documentation/CoreFoundation/CFBoolean> and indicates whether this cryptographic key can be used to decrypt data.

On key creation, if not explicitly specified, this attribute defaults to <doc://com.apple.documentation/documentation/CoreFoundation/kCFBooleanTrue> for private keys and <doc://com.apple.documentation/documentation/CoreFoundation/kCFBooleanFalse> for public keys.
