|
.SH "DESCRIPTION"
|
|
The \fBspkac\fR 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.
|
|
.SH "COMMAND OPTIONS"
|
|
.Ip "\fB\-in filename\fR" 4
|
|
This specifies the input filename to read from or standard input if this
|
|
option is not specified. Ignored if the \fB\-key\fR option is used.
|
|
.Ip "\fB\-out filename\fR" 4
|
|
specifies the output filename to write to or standard output by
|
|
default.
|
|
.Ip "\fB\-key keyfile\fR" 4
|
|
create an \s-1SPKAC\s0 file using the private key in \fBkeyfile\fR. The
|
|
\fB\-in\fR, \fB\-noout\fR, \fB\-spksect\fR and \fB\-verify\fR options are ignored if
|
|
present.
|
|
.Ip "\fB\-passin password\fR" 4
|
|
the input file password source. For more information about the format of \fBarg\fR
|
|
see the \fB\s-1PASS\s0 \s-1PHRASE\s0 \s-1ARGUMENTS\s0\fR section in the \fIopenssl(1)|openssl(1)\fR manpage.
|
|
.Ip "\fB\-challenge string\fR" 4
|
|
specifies the challenge string if an \s-1SPKAC\s0 is being created.
|
|
.Ip "\fB\-spkac spkacname\fR" 4
|
|
allows an alternative name form the variable containing the
|
|
\s-1SPKAC\s0. The default is \*(L"\s-1SPKAC\s0\*(R". This option affects both
|
|
generated and input \s-1SPKAC\s0 files.
|
|
.Ip "\fB\-spksect section\fR" 4
|
|
allows an alternative name form the section containing the
|
|
\s-1SPKAC\s0. The default is the default section.
|
|
.Ip "\fB\-noout\fR" 4
|
|
don't output the text version of the \s-1SPKAC\s0 (not used if an
|
|
\s-1SPKAC\s0 is being created).
|
|
.Ip "\fB\-pubkey\fR" 4
|
|
output the public key of an \s-1SPKAC\s0 (not used if an \s-1SPKAC\s0 is
|
|
being created).
|
|
.Ip "\fB\-verify\fR" 4
|
|
verifies the digital signature on the supplied \s-1SPKAC\s0.
|
|
.SH "EXAMPLES"
|
|
Print out the contents of an SPKAC:
|
|
.PP
|
|
.Vb 1
|
|
\& openssl spkac -in spkac.cnf
|
|
.Ve
|
|
Verify the signature of an SPKAC:
|
|
.PP
|
|
.Vb 1
|
|
\& openssl spkac -in spkac.cnf -noout -verify
|
|
.Ve
|
|
Create an SPKAC using the challenge string \*(L"hello":
|
|
.PP
|
|
.Vb 1
|
|
\& openssl spkac -key key.pem -challenge hello -out spkac.cnf
|
|
.Ve
|
|

|
|
.SH "NOTES"
|
|
A created SPKAC with suitable DN components appended can be fed into
|
|
the \fBca\fR utility.
|
|
.PP
|
|
SPKACs are typically generated by Netscape when a form is submitted
|
|
containing the \fBKEYGEN\fR tag as part of the certificate enrollment
|
|
process.
|
|
.PP
|
|
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 \*(L"replay attack\*(R".
