shall be specified, the NULL pointer can be used for B<verify_callback>. In
this case last B<verify_callback> set specifically for this B<ssl> remains. If
no special B<callback> was set before, the default callback for the underlying
-B<ctx> is used, that was valid at the the time B<ssl> was created with
+B<ctx> is used, that was valid at the time B<ssl> was created with
L<SSL_new(3)|SSL_new(3)>.
SSL_CTX_set_verify_depth() sets the maximum B<depth> for the certificate chain
failure, if wished. The callback realizes a verification depth limit with
more informational output.
-All verification errors are printed, informations about the certificate chain
-are printed on request.
+All verification errors are printed; information about the certificate chain
+is printed on request.
The example is realized for a server that does allow but not require client
certificates.
