The public portion of an asymmetric key pair.

```
class LAPublicKey
```

## Topics

### Checking algorithm support

[`canEncrypt(using:)`](/documentation/LocalAuthentication/LAPublicKey/canEncrypt(using:))

Checks whether the algorithm you supply is valid for encrypting data with the key.

[`canVerify(using:)`](/documentation/LocalAuthentication/LAPublicKey/canVerify(using:))

Checks whether the algorithm you supply is valid for verifying signatures with the key.

### Performing cryptographic operations

[`encrypt(_:algorithm:completion:)`](/documentation/LocalAuthentication/LAPublicKey/encrypt(_:algorithm:completion:))

Encrypts the data you supply with a given algorithm.

[`exportBytes(completion:)`](/documentation/LocalAuthentication/LAPublicKey/exportBytes(completion:))

Exports the data that represents a public key.

[`verify(_:signature:algorithm:completion:)`](/documentation/LocalAuthentication/LAPublicKey/verify(_:signature:algorithm:completion:))

Verifies a digital signature for the data you supply.
