+
+   FC_Digest - digest a block of data.
+
+`Syntax <#syntax>`__
+~~~~~~~~~~~~~~~~~~~~
+
+.. container::
+
+   .. code:: eval
+
+      CK_RV FC_Digest(
+        CK_SESSION_HANDLE hSession,
+        CK_BYTE_PTR pData,
+        CK_ULONG usDataLen,
+        CK_BYTE_PTR pDigest,
+        CK_ULONG_PTR pusDigestLen
+      );
+
+`Parameters <#parameters>`__
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+.. container::
+
+   ``hSession``
+      [in] session handle.
+   ``pData``
+      [in] pointer to data block.
+   ``usDataLen``
+      [in] length of the data in bytes.
+   ``pDigest``
+      [out] pointer to location where recovered data is to be stored.
+   ``pusDigestLen``
+      [in, out] pointer to the maximum size of the output buffer, replaced by the length of the
+      message digest if the operation is successful.
+
+`Description <#description>`__
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+.. container::
+
+   ``FC_Digest`` digests a message in a single operation according to the attributes of the previous
+   call to ``FC_DigestInit``.
+
+   A user may call ``FC_Digest`` without logging into the token (to assume the NSS User role).
