.SH "DESCRIPTION"

|
|
.IX Header "DESCRIPTION"
|
||
|
|
The Online Certificate Status Protocol (\s-1OCSP\s0) enables applications to
|
||
|
|
determine the (revocation) state of an identified certificate (\s-1RFC 2560\s0).
|
||
|
|
.PP
|
||
|
|
The \fBocsp\fR command performs many common \s-1OCSP\s0 tasks. It can be used
|
||
|
|
to print out requests and responses, create requests and send queries
|
||
|
|
to an \s-1OCSP\s0 responder and behave like a mini \s-1OCSP\s0 server itself.
|
||
|
|
.SH "OPTIONS"
|
||
|
|
.IX Header "OPTIONS"
|
||
|
|
This command operates as either a client or a server.
|
||
|
|
The options are described below, divided into those two modes.
|
||
|
|
.SS "\s-1OCSP\s0 Client Options"
|
||
|
|
.IX Subsection "OCSP Client Options"
|
||
|
|
.IP "\fB\-help\fR" 4
|
||
|
|
.IX Item "-help"
|
||
|
|
Print out a usage message.
|
||
|
|
.IP "\fB\-out filename\fR" 4
|
||
|
|
.IX Item "-out filename"
|
||
|
|
specify output filename, default is standard output.
|
||
|
|
.IP "\fB\-issuer filename\fR" 4
|
||
|
|
.IX Item "-issuer filename"
|
||
|
|
This specifies the current issuer certificate. This option can be used
|
||
|
|
multiple times. The certificate specified in \fBfilename\fR must be in
|
||
|
|
\&\s-1PEM\s0 format. This option \fB\s-1MUST\s0\fR come before any \fB\-cert\fR options.
|
||
|
|
.IP "\fB\-cert filename\fR" 4
|
||
|
|
.IX Item "-cert filename"
|
||
|
|
Add the certificate \fBfilename\fR to the request. The issuer certificate
|
||
|
|
is taken from the previous \fBissuer\fR option, or an error occurs if no
|
||
|
|
issuer certificate is specified.
|
||
|
|
.IP "\fB\-serial num\fR" 4
|
||
|
|
.IX Item "-serial num"
|
||
|
|
Same as the \fBcert\fR option except the certificate with serial number
|
||
|
|
\&\fBnum\fR is added to the request. The serial number is interpreted as a
|
||
|
|
decimal integer unless preceded by \fB0x\fR. Negative integers can also
|
||
|
|
be specified by preceding the value by a \fB\-\fR sign.
|
||
|
|
.IP "\fB\-signer filename\fR, \fB\-signkey filename\fR" 4
|
||
|
|
.IX Item "-signer filename, -signkey filename"
|
||
|
|
Sign the \s-1OCSP\s0 request using the certificate specified in the \fBsigner\fR
|
||
|
|
option and the private key specified by the \fBsignkey\fR option. If
|
||
|
|
the \fBsignkey\fR option is not present then the private key is read
|
||
|
|
from the same file as the certificate. If neither option is specified then
|
||
|
|
the \s-1OCSP\s0 request is not signed.
|
||
|
|
.IP "\fB\-sign_other filename\fR" 4
|
||
|
|
.IX Item "-sign_other filename"
|
||
|
|
Additional certificates to include in the signed request.
|
||
|
|
.IP "\fB\-nonce\fR, \fB\-no_nonce\fR" 4
|
||
|
|
.IX Item "-nonce, -no_nonce"
|
||
|
|
Add an \s-1OCSP\s0 nonce extension to a request or disable \s-1OCSP\s0 nonce addition.
|
||
|
|
Normally if an \s-1OCSP\s0 request is input using the \fBreqin\fR option no
|
||
|
|
nonce is added: using the \fBnonce\fR option will force addition of a nonce.
|
||
|
|
If an \s-1OCSP\s0 request is being created (using \fBcert\fR and \fBserial\fR options)
|
||
|
|
a nonce is automatically added specifying \fBno_nonce\fR overrides this.
|
||
|
|
.IP "\fB\-req_text\fR, \fB\-resp_text\fR, \fB\-text\fR" 4
|
||
|
|
.IX Item "-req_text, -resp_text, -text"
|
||
|
|
Print out the text form of the \s-1OCSP\s0 request, response or both respectively.
|
||
|
|
.IP "\fB\-reqout file\fR, \fB\-respout file\fR" 4
|
||
|
|
.IX Item "-reqout file, -respout file"
|
||
|
|
Write out the \s-1DER\s0 encoded certificate request or response to \fBfile\fR.
|
||
|
|
.IP "\fB\-reqin file\fR, \fB\-respin file\fR" 4
|
||
|
|
.IX Item "-reqin file, -respin file"
|
||
|
|
Read \s-1OCSP\s0 request or response file from \fBfile\fR. These option are ignored
|
||
|
|
if \s-1OCSP\s0 request or response creation is implied by other options (for example
|
||
|
|
with \fBserial\fR, \fBcert\fR and \fBhost\fR options).
|
||
|
|
.IP "\fB\-url responder_url\fR" 4
|
||
|
|
.IX Item "-url responder_url"
|
||
|
|
Specify the responder \s-1URL.\s0 Both \s-1HTTP\s0 and \s-1HTTPS\s0 (\s-1SSL/TLS\s0) URLs can be specified.
|
||
|
|
.IP "\fB\-host hostname:port\fR, \fB\-path pathname\fR" 4
|
||
|
|
.IX Item "-host hostname:port, -path pathname"
|
||
|
|
If the \fBhost\fR option is present then the \s-1OCSP\s0 request is sent to the host
|
||
|
|
\&\fBhostname\fR on port \fBport\fR. \fBpath\fR specifies the \s-1HTTP\s0 path name to use
|
||
|
|
or \*(L"/\*(R" by default. This is equivalent to specifying \fB\-url\fR with scheme
|
||
|
|
http:// and the given hostname, port, and pathname.
|
||
|
|
.IP "\fB\-header name=value\fR" 4
|
||
|
|
.IX Item "-header name=value"
|
||
|
|
Adds the header \fBname\fR with the specified \fBvalue\fR to the \s-1OCSP\s0 request
|
||
|
|
that is sent to the responder.
|
||
|
|
This may be repeated.
|
||
|
|
.IP "\fB\-timeout seconds\fR" 4
|
||
|
|
.IX Item "-timeout seconds"
|
||
|
|
Connection timeout to the \s-1OCSP\s0 responder in seconds.
|
||
|
|
On \s-1POSIX\s0 systems, when running as an \s-1OCSP\s0 responder, this option also limits
|
||
|
|

File containing additional certificates to search when attempting to locate

|

Don't attempt to verify the \s-1OCSP\s0 response signature or the nonce

disables all verification of the responders certificate.

Ignore certificates contained in the \s-1OCSP\s0 response when searching for the

signers certificate. With this option the signers certificate must be specified

with either the \fB\-verify_other\fR or \fB\-VAfile\fR options.
|

.IP "\fB\-no_signature_verify\fR" 4
|

.IX Item "-no_signature_verify"
|
||
|
|
Don't check the signature on the \s-1OCSP\s0 response. Since this option

|
|
tolerates invalid signatures on \s-1OCSP\s0 responses it will normally only be
|
||
|
|
used for testing purposes.
|

|
|
.IP "\fB\-no_cert_verify\fR" 4
|

.IX Item "-no_cert_verify"
|

|
|
Don't verify the \s-1OCSP\s0 response signers certificate at all. Since this

option allows the \s-1OCSP\s0 response to be signed by any certificate it should

certificates.

.IP "\fB\-no_explicit\fR" 4
|

Do not explicitly trust the root \s-1CA\s0 if it is set to be trusted for \s-1OCSP\s0 signing.

.IP "\fB\-no_cert_checks\fR" 4

.IX Item "-no_cert_checks"
|

|
|
Don't perform any additional checks on the \s-1OCSP\s0 response signers certificate.
|
||
|
|
That is do not make any checks to see if the signers certificate is authorised
|
||
|
|
to provide the necessary status information: as a result this option should
|
||
|
|
only be used for testing purposes.

|

.IP "\fB\-validity_period nsec\fR, \fB\-status_age age\fR" 4
|
||
|
|
.IX Item "-validity_period nsec, -status_age age"
|
||
|
|
These options specify the range of times, in seconds, which will be tolerated
|
||
|
|
in an \s-1OCSP\s0 response. Each certificate status response includes a \fBnotBefore\fR
|
||
|
|
time and an optional \fBnotAfter\fR time. The current time should fall between
|
||
|
|
these two values, but the interval between the two times may be only a few
|
||
|
|
seconds. In practice the \s-1OCSP\s0 responder and clients clocks may not be precisely
|
||
|
|
synchronised and so such a check may fail. To avoid this the
|
||
|
|
\&\fB\-validity_period\fR option can be used to specify an acceptable error range in
|
||
|
|
seconds, the default value is 5 minutes.
|
||
|
|
.Sp
|
||
|
|
If the \fBnotAfter\fR time is omitted from a response then this means that new
|
||
|
|
status information is immediately available. In this case the age of the
|
||
|
|
\&\fBnotBefore\fR field is checked to see it is not older than \fBage\fR seconds old.
|
||
|
|
By default this additional check is not performed.
|
||
|
|
.IP "\fB\-\f(BIdigest\fB\fR" 4
|

|
|
.IX Item "-digest"
|
||
|
|
This option sets digest algorithm to use for certificate identification in the
|
||
|
|
\&\s-1OCSP\s0 request. Any digest supported by the OpenSSL \fBdgst\fR command can be used.
|
||
|
|
The default is \s-1SHA\-1.\s0 This option may be used multiple times to specify the

digest used by subsequent certificate identifiers.
