-The following constructions are supported:
+The following constructions are included:
 
-| Committing AEAD Construction | Encryption? | Decryption? | Commitment Security |
-|------------------------------|-------------|-------------|---------------------|
-| ["Padding Fix"]              | Yes         | Yes         | Key only            |
-| [CTX]                        | Yes         | No          | All inputs          |
-| CTXish-HMAC (see code docs)  | Yes         | Yes         | All inputs          |

 CTX decryption is not implemented because verifying the tag at decryption time
 requires accessing the expected original tag of the wrapped AEAD, which is
