+/**
+ * Class used for displaying confirmation prompts.
+ *
+ * <p>Confirmation prompts are prompts shown to the user to confirm a given text and are
+ * implemented in a way that a positive response indicates with high confidence that the user has
+ * seen the given text, even if the Android framework (including the kernel) was
+ * compromised. Implementing confirmation prompts with these guarantees requires dedicated
+ * hardware-support and may not always be available.
+ *
+ * <p>Confirmation prompts are typically used with an external entitity - the <i>Relying Party</i> -
+ * in the following way. The setup steps are as follows:
+ * <ul>
+ * <li> Before first use, the application generates a key-pair with the
+ * {@link android.security.keystore.KeyGenParameterSpec.Builder#setUserConfirmationRequired
+ * CONFIRMATION tag} set. Device attestation,
+ * e.g. {@link java.security.KeyStore#getCertificateChain getCertificateChain()}, is used to
+ * generate a certificate chain that includes the public key (<code>Kpub</code> in the following)
+ * of the newly generated key.
+ * <li> The application sends <code>Kpub</code> and the certificate chain resulting from device
+ * attestation to the <i>Relying Party</i>.
+ * <li> The <i>Relying Party</i> validates the certificate chain which involves checking the root
+ * certificate is what is expected (e.g. a certificate from Google), each certificate signs the
+ * next one in the chain, ending with <code>Kpub</code>, and that the attestation certificate
+ * asserts that <code>Kpub</code> has the
+ * {@link android.security.keystore.KeyGenParameterSpec.Builder#setUserConfirmationRequired
+ * CONFIRMATION tag} set.
+ * Additionally the relying party stores <code>Kpub</code> and associates it with the device
+ * it was received from.
+ * </ul>
+ *
+ * <p>The <i>Relying Party</i> is typically an external device (for example connected via
+ * Bluetooth) or application server.
+ *
+ * <p>Before executing a transaction which requires a high assurance of user content, the
+ * application does the following:
+ * <ul>
+ * <li> The application gets a cryptographic nonce from the <i>Relying Party</i> and passes this as
+ * the <code>extraData</code> (via the Builder helper class) to the
+ * {@link #presentPrompt presentPrompt()} method. The <i>Relying Party</i> stores the nonce locally
+ * since it'll use it in a later step.
+ * <li> If the user approves the prompt a <i>Confirmation Response</i> is returned in the
+ * {@link ConfirmationCallback#onConfirmedByUser onConfirmedByUser(byte[])} callback as the
+ * <code>dataThatWasConfirmed</code> parameter. This blob contains the text that was shown to the
+ * user, the <code>extraData</code> parameter, and possibly other data.
+ * <li> The application signs the <i>Confirmation Response</i> with the previously created key and
+ * sends the blob and the signature to the <i>Relying Party</i>.
+ * <li> The <i>Relying Party</i> checks that the signature was made with <code>Kpub</code> and then
+ * extracts <code>promptText</code> matches what is expected and <code>extraData</code> matches the
+ * previously created nonce. If all checks passes, the transaction is executed.
+ * </ul>
+ *
+ * <p>A common way of implementing the "<code>promptText</code> is what is expected" check in the
+ * last bullet, is to have the <i>Relying Party</i> generate <code>promptText</code> and store it
+ * along the nonce in the <code>extraData</code> blob.
