Some public key algorithms may override this choice. For instance, DSA
signatures always use SHA1, GOST R 34.10 signatures always use
-GOST R 34.11-94 (B<-md_gost94>).
+GOST R 34.11-94 (B<-md_gost94>), Ed25519 and Ed448 never use any digest.
=item B<-config filename>
Sets subject name for new request or supersedes the subject name
when processing a request.

-characters may be escaped by \ (backslash), no spaces are skipped.
+The arg must be formatted as I</type0=value0/type1=value1/type2=...>.
+Keyword characters may be escaped by \ (backslash), and whitespace is retained.
+Empty values are permitted, but the corresponding type will not be included
+in the request.
=item B<-multivalue-rdn>
=item B<-days n>
When the B<-x509> option is being used this specifies the number of
-days to certify the certificate for, otherwise it is ignored.
-The default is 30 days.
+days to certify the certificate for, otherwise it is ignored. B<n> should
+be a positive integer. The default is 30 days.
=item B<-set_serial n>
Serial number to use when outputting a self signed certificate. This
may be specified as a decimal value or a hex value if preceded by B<0x>.
+=item B<-addext ext>
+
+Add a specific extension to the certificate (if the B<-x509> option is
+present) or certificate request. The argument must have the form of
+a key=value pair as it would appear in a config file.
+
+This option can be given multiple times.

+This option specifies the digest algorithm to use. Any digest supported by the
