+  Check input P7Data is a wrapped ContentInfo structure or not. If not construct
+  a new structure to wrap P7Data.
+
+  Caution: This function may receive untrusted input.
+  UEFI Authenticated Variable is external input, so this function will do basic
+  check for PKCS#7 data structure.
+
+  @param[in]  P7Data       Pointer to the PKCS#7 message to verify.
+  @param[in]  P7Length     Length of the PKCS#7 message in bytes.
+  @param[out] WrapFlag     If TRUE P7Data is a ContentInfo structure, otherwise
+                           return FALSE.
+  @param[out] WrapData     If return status of this function is TRUE:
+                           1) when WrapFlag is TRUE, pointer to P7Data.
+                           2) when WrapFlag is FALSE, pointer to a new ContentInfo
+                           structure. It's caller's responsibility to free this
+                           buffer.
+  @param[out] WrapDataSize Length of ContentInfo structure in bytes.
+
+  @retval     TRUE         The operation is finished successfully.
+  @retval     FALSE        The operation is failed due to lack of resources.
