the output file password source. For more information about the format of B<arg>
see the B<PASS PHRASE ARGUMENTS> section in L<openssl(1)|openssl(1)>.

-These options encrypt the private key with the DES, triple DES, or the
-IDEA ciphers respectively before outputting it. A pass phrase is prompted for.
+These options encrypt the private key with the specified
+cipher before outputting it. A pass phrase is prompted for.
If none of these options is specified the key is written in plain text. This
means that using the B<dsa> utility to read in an encrypted key with no
encryption option can be used to remove the pass phrase from a key, or by
key will be output instead. This option is automatically set if the input is
a public key.
+=item B<-engine id>
+
+specifying an engine (by its unique B<id> string) will cause B<dsa>
+to attempt to obtain a functional reference to the specified engine,
+thus initialising it if needed. The engine will then be set as the default
+for all available algorithms.
