 #### `email_auth.circom`
 A circuit to verify that a message in the subject is authorized by a user of an account salt, derived from an email address in the From field and a random field value called account code.
 
+The circuit has the following blueprint ID and download URLs for the proving key and witness generator:
+```json

+  "blueprintId": "7f3c3bc2-7c5d-4682-8d7f-f3d2f9046722",

+}
+```

+It takes as input the following data:
+1. a padded email header `padded_header`.
 It takes as input the following data:
 1. a padded email header `padded_header`.
 2. the bytes of the padded email header `padded_header_len`.
