=head1 DESCRIPTION
=item B<-inform DER|PEM>
-This specifies the input format DER or PEM.
+This specifies the input format DER or PEM. The default format is PEM.
=item B<-outform DER|PEM>
-This specifies the output format, the options have the same meaning as the
-B<-inform> option.
+This specifies the output format, the options have the same meaning and default
+as the B<-inform> option.
=item B<-in filename>
with the appropriate encryption algorithm (if any). If the B<-traditional>
option is specified then the older "traditional" format is used instead.
-=item B<-cipher>
+=item B<-I<cipher>>
These options encrypt the private key with the supplied cipher. Any algorithm
name accepted by EVP_get_cipherbyname() is acceptable such as B<des3>.
thus initialising it if needed. The engine will then be set as the default
for all available algorithms.
+=item B<-check>
+
+This option checks the consistency of a key pair for both public and private
+components.
