public enum KeySpec
extends Enum<KeySpec>

The key spec, represents the cryptographic configuration of keys.

Example:

 Key key = Key.Builder.create(this, "MyKey")
         .keySpec(KeySpec.ECC_SECG_P256K1) // Default to SYMMETRIC_DEFAULT
         .keyUsage(KeyUsage.SIGN_VERIFY)
         .build();
