+
+The @code{gpgme_revocation_key_t} type is a pointer to a revocation key
+structure.  Revocation key structures are one component of a
+@code{gpgme_key_t} object.  They provide information about the designated
+revocation keys for a key.
+
+The revocation key structure has the following members:
+
+@table @code
+@item gpgme_revocation_key_t next
+This is a pointer to the next revocation key structure in the linked list,
+or @code{NULL} if this is the last element.
+
+@item gpgme_pubkey_algo_t pubkey_algo
+This is the public key algorithm of the revocation key.
+
+@item char *fpr
+This is the fingerprint of the revocation_key in hexadecimal digits.
+
+@item unsigned int key_class
+This is the class of the revocation key signature subpacket.
+
+@item unsigned int sensitive : 1
+This is true if the revocation key is marked as sensitive.
