=head1 DESCRIPTION
|
|
|
|
This command processes Netscape signed public key and challenge
|
|
(SPKAC) files. It can print out their contents, verify the signature and
|
|
produce its own SPKACs from a supplied private key.
|
|
|
|
=head1 OPTIONS
|
|
|
|
=over 4
|
|
|
|
=item B<-help>
|
|
|
|
Print out a usage message.
|
|
|
|
=item B<-in> I<filename>
|
|
|
|
This specifies the input filename to read from or standard input if this
|
|
option is not specified. Ignored if the B<-key> option is used.
|
|
|
|
=item B<-out> I<filename>
|
|
|
|
Specifies the output filename to write to or standard output by
|
|
default.
|
|
|
|
=item B<-key> I<keyfile>
|
|
|
|
Create an SPKAC file using the private key in I<keyfile>. The
|
|
B<-in>, B<-noout>, B<-spksect> and B<-verify> options are ignored if
|
|
present.
|
|
|
|
=item B<-keyform> B<DER>|B<PEM>|B<P12>|B<ENGINE>
|
|
|
|
The key format; the default is B<PEM>.
|
|
The only value with effect is B<ENGINE>; all others have become obsolete.
|
|
See L<openssl(1)/Format Options> for details.
|
|
|
|
=item B<-passin> I<arg>
|
|
|
|
The input file password source. For more information about the format of I<arg>
|
|
see L<openssl(1)/Pass Phrase Options>.
|
|
|
|
=item B<-challenge> I<string>
|
|
|
|
Specifies the challenge string if an SPKAC is being created.
|
|
|
|
=item B<-spkac> I<spkacname>
|
|
|
|
Allows an alternative name form the variable containing the
|
|
SPKAC. The default is "SPKAC". This option affects both
|
|
generated and input SPKAC files.
|
|
|
|
=item B<-spksect> I<section>
|
|
|
|
Allows an alternative name form the section containing the
|
|
SPKAC. The default is the default section.
|
|
|
|
=item B<-noout>
|
|
|
|
Don't output the text version of the SPKAC (not used if an
|
|
SPKAC is being created).
|
|
|
|
=item B<-pubkey>
|
|
|
|
Output the public key of an SPKAC (not used if an SPKAC is
|
|
being created).
|
|
|
|
=item B<-verify>
|
|
|
|
Verifies the digital signature on the supplied SPKAC.

=head1 EXAMPLES
|
|
|
|
Print out the contents of an SPKAC:
|
|
|
|
openssl spkac -in spkac.cnf
|
|
|
|
Verify the signature of an SPKAC:
|
|
|
|
openssl spkac -in spkac.cnf -noout -verify
|
|
|
|
Create an SPKAC using the challenge string "hello":
|
|
|
|
openssl spkac -key key.pem -challenge hello -out spkac.cnf
|
|
|
|
Example of an SPKAC, (long lines split up for clarity):
|
|
|
|
SPKAC=MIG5MGUwXDANBgkqhkiG9w0BAQEFAANLADBIAkEA\

|
=head1 NOTES
|
|
|
|
A created SPKAC with suitable DN components appended can be fed to
|
|
L<openssl-ca(1)>.
|
|
|
|
SPKACs are typically generated by Netscape when a form is submitted
|
|
containing the B<KEYGEN> tag as part of the certificate enrollment
|
|
process.
|
|
|
|
The challenge string permits a primitive form of proof of possession
|
|
of private key. By checking the SPKAC signature and a random challenge
|
|
string some guarantee is given that the user knows the private key
|
|
corresponding to the public key being certified. This is important in
|
|
some applications. Without this it is possible for a previous SPKAC
|
|
to be used in a "replay attack".
