+ * @brief Provide Credential based challenge
+ *
+ * Credential here means the certificate issued by a trust anchor. Once the requester
+ * could proof his/her possession of an existing certificate from other certificate, th
+ * requester could finish the challenge.
+ *
+ * The main process of this challenge module is:
+ * 1. Requester provides a certificate signed by that trusted certificate as credential.
+ * 2. The challenge module will verify the signature of the credential.
+ *
+ * There are several challenge status in EMAIL challenge:
+ * FAILURE_INVALID_SIG: When the credential cannot be validated.
