If the NULL-DN (\f(CW"/"\fR) is given then no subject is placed in the template. Default is the subject \s-1DN\s0 of any PKCS#10 \s-1CSR\s0 given with the \fB\-csr\fR option. For \s-1KUR,\s0 a further fallback is the subject \s-1DN\s0 of the reference certificate (see \fB\-oldcert\fR) if provided. This fallback is used for \s-1IR\s0 and \s-1CR\s0 only if no SANs are set. .Sp If provided and neither \fB\-cert\fR nor \fB\-oldcert\fR is given, the subject \s-1DN\s0 is used as fallback sender of outgoing \s-1CMP\s0 messages. .Sp The argument must be formatted as \fI/type0=value0/type1=value1/type2=...\fR. Special characters may be escaped by \f(CW\*(C`\e\*(C'\fR (backslash); whitespace is retained. Empty values are permitted, but the corresponding type will not be included. Giving a single \f(CW\*(C`/\*(C'\fR will lead to an empty sequence of RDNs (a NULL-DN).

For details see the description of the \fB\-subject\fR option. .IP "\fB\-days\fR \fInumber\fR" 4 .IX Item "-days number" Number of days the new certificate is requested to be valid for, counting from the current time of the host. Also triggers the explicit request that the validity period starts from the current time (as seen by the host). .IP "\fB\-reqexts\fR \fIname\fR" 4 .IX Item "-reqexts name" Name of section in OpenSSL config file defining certificate request extensions. If the \fB\-csr\fR option is present, these extensions augment the extensions contained the given PKCS#10 \s-1CSR,\s0 overriding any extensions with same OIDs. .IP "\fB\-sans\fR \fIspec\fR" 4 .IX Item "-sans spec" One or more \s-1IP\s0 addresses, \s-1DNS\s0 names, or URIs separated by commas or whitespace (where in the latter case the whole argument must be enclosed in \*(L"...\*(R") to add as Subject Alternative Name(s) (\s-1SAN\s0) certificate request extension. If the special element \*(L"critical\*(R" is given the SANs are flagged as critical. Cannot be used if any Subject Alternative Name extension is set via \fB\-reqexts\fR. .IP "\fB\-san_nodefault\fR" 4 .IX Item "-san_nodefault" When Subject Alternative Names are not given via \fB\-sans\fR nor defined via \fB\-reqexts\fR, they are copied by default from the reference certificate (see \fB\-oldcert\fR). This can be disabled by giving the \fB\-san_nodefault\fR option. .IP "\fB\-policies\fR \fIname\fR" 4 .IX Item "-policies name" Name of section in OpenSSL config file defining policies to be set as certificate request extension. This option cannot be used together with \fB\-policy_oids\fR. .IP "\fB\-policy_oids\fR \fInames\fR" 4 .IX Item "-policy_oids names" One or more \s-1OID\s0(s), separated by commas and/or whitespace (where in the latter case the whole argument must be enclosed in \*(L"...\*(R") to add as certificate policies request extension.

With \fB\-cmd\fR \fIp10cr\fR it is used directly in a legacy P10CR message. .Sp When used with \fB\-cmd\fR \fIir\fR, \fIcr\fR, or \fIkur\fR, it is transformed into the respective regular \s-1CMP\s0 request. In this case, a private key must be provided (with \fB\-newkey\fR or \fB\-key\fR) for the proof of possession (unless \fB\-popo\fR \fI\-1\fR or \fB\-popo\fR \fI0\fR is used) and the respective public key is placed in the certification request (rather than taking over the public key contained in the PKCS#10 \s-1CSR\s0). .Sp PKCS#10 \s-1CSR\s0 input may also be used with \fB\-cmd\fR \fIrr\fR to specify the certificate to be revoked via the included subject name and public key. .IP "\fB\-out_trusted\fR \fIfilenames\fR|\fIuris\fR" 4 .IX Item "-out_trusted filenames|uris" Trusted certificate(s) to use for validating the newly enrolled certificate. During this verification, any certificate status checking is disabled. .Sp Multiple sources may be given, separated by commas and/or whitespace (where in the latter case the whole argument must be enclosed in \*(L"...\*(R"). Each source may contain multiple certificates. .Sp The certificate verification options \&\fB\-verify_hostname\fR, \fB\-verify_ip\fR, and \fB\-verify_email\fR only affect the certificate verification enabled via this option. .IP "\fB\-implicit_confirm\fR" 4 .IX Item "-implicit_confirm" Request implicit confirmation of newly enrolled certificates. .IP "\fB\-disable_confirm\fR" 4 .IX Item "-disable_confirm" Do not send certificate confirmation message for newly enrolled certificate without requesting implicit confirmation to cope with broken servers not supporting implicit confirmation correctly. \&\fB\s-1WARNING:\s0\fR This leads to behavior violating \s-1RFC 4210.\s0 .IP "\fB\-certout\fR \fIfilename\fR" 4 .IX Item "-certout filename" The file where the newly enrolled certificate should be saved. .IP "\fB\-chainout\fR \fIfilename\fR" 4 .IX Item "-chainout filename" The file where the chain of the newly enrolled certificate should be saved. .SS "Certificate enrollment and revocation options" .IX Subsection "Certificate enrollment and revocation options" .IP "\fB\-oldcert\fR \fIfilename\fR|\fIuri\fR" 4 .IX Item "-oldcert filename|uri" The certificate to be updated (i.e., renewed or re-keyed) in Key Update Request (\s-1KUR\s0) messages or to be revoked in Revocation Request (\s-1RR\s0) messages. For \s-1KUR\s0 the certificate to be updated defaults to \fB\-cert\fR, and the resulting certificate is called \fIreference certificate\fR. For \s-1RR\s0 the certificate to be revoked can also be specified using \fB\-csr\fR. .Sp The reference certificate, if any, is also used for deriving default subject \s-1DN\s0 and Subject Alternative Names and the default issuer entry in the requested certificate template of an \s-1IR/CR/KUR.\s0 Its public key is used as a fallback in the template of certification requests. Its subject is used as sender of outgoing messages if \fB\-cert\fR is not given. Its issuer is used as default recipient in \s-1CMP\s0 message headers if neither \fB\-recipient\fR, \fB\-srvcert\fR, nor \fB\-issuer\fR is given. .IP "\fB\-revreason\fR \fInumber\fR" 4 .IX Item "-revreason number" Set CRLReason to be included in revocation request (\s-1RR\s0); values: \f(CW0\fR..\f(CW10\fR or \f(CW\*(C`\-1\*(C'\fR for none (which is the default). .Sp Reason numbers defined in \s-1RFC 5280\s0 are: .Sp .Vb 10 \& CRLReason ::= ENUMERATED { \& unspecified (0), \& keyCompromise (1), \& cACompromise (2), \& affiliationChanged (3), \& superseded (4), \& cessationOfOperation (5), \& certificateHold (6), \& \-\- value 7 is not used \& removeFromCRL (8), \& privilegeWithdrawn (9), \& aACompromise (10) \& } .Ve .SS "Message transfer options" .IX Subsection "Message transfer options" .IP "\fB\-server\fR \fI[http[s]://][userinfo@]host[:port][/path][?query][#fragment]\fR" 4 .IX Item "-server [http[s]://][userinfo@]host[:port][/path][?query][#fragment]" The \s-1DNS\s0 hostname or \s-1IP\s0 address and optionally port of the \s-1CMP\s0 server to connect to using \s-1HTTP\s0(S).

So special care must be taken setting up server authentication using \fB\-trusted\fR and related options for certificate-based authentication or \fB\-secret\fR for MAC-based protection. .PP When setting up \s-1CMP\s0 configurations and experimenting with enrollment options typically various errors occur until the configuration is correct and complete. When the \s-1CMP\s0 server reports an error the client will by default check the protection of the \s-1CMP\s0 response message. Yet some \s-1CMP\s0 services tend not to protect negative responses. In this case the client will reject them, and thus their contents are not shown although they usually contain hints that would be helpful for diagnostics. For assisting in such cases the \s-1CMP\s0 client offers a workaround via the \&\fB\-unprotected_errors\fR option, which allows accepting such negative messages. .SH "EXAMPLES" .IX Header "EXAMPLES" .SS "Simple examples using the default OpenSSL configuration file" .IX Subsection "Simple examples using the default OpenSSL configuration file" This \s-1CMP\s0 client implementation comes with demonstrative \s-1CMP\s0 sections in the example configuration file \fIopenssl/apps/openssl.cnf\fR, which can be used to interact conveniently with the Insta Demo \s-1CA.\s0 .PP In order to enroll an initial certificate from that \s-1CA\s0 it is sufficient to issue the following shell commands. .PP .Vb 1 \& export OPENSSL_CONF=/path/to/openssl/apps/openssl.cnf .Ve .PP .Vb 2 \& openssl genrsa \-out insta.priv.pem \& openssl cmp \-section insta .Ve .PP This should produce the file \fIinsta.cert.pem\fR containing a new certificate for the private key held in \fIinsta.priv.pem\fR. It can be viewed using, e.g., .PP .Vb 1 \& openssl x509 \-noout \-text \-in insta.cert.pem .Ve .PP In case the network setup requires using an \s-1HTTP\s0 proxy it may be given as usual via the environment variable \fBhttp_proxy\fR or via the \fB\-proxy\fR option in the configuration file or the \s-1CMP\s0 command-line argument \fB\-proxy\fR, for example .PP .Vb 1 \& \-proxy http://192.168.1.1:8080 .Ve .PP In the Insta Demo \s-1CA\s0 scenario both clients and the server may use the pre-shared secret \fIinsta\fR and the reference value \fI3078\fR to authenticate to each other. .PP Alternatively, \s-1CMP\s0 messages may be protected in signature-based manner, where the trust anchor in this case is \fIinsta.ca.crt\fR and the client may use any certificate already obtained from that \s-1CA,\s0 as specified in the \fB[signature]\fR section of the example configuration. This can be used in combination with the \fB[insta]\fR section simply by .PP .Vb 1 \& openssl cmp \-section insta,signature .Ve .PP By default the \s-1CMP IR\s0 message type is used, yet \s-1CR\s0 works equally here. This may be specified directly at the command line: .PP .Vb 1 \& openssl cmp \-section insta \-cmd cr .Ve .PP or by referencing in addition the \fB[cr]\fR section of the example configuration: .PP .Vb 1 \& openssl cmp \-section insta,cr .Ve .PP In order to update the enrolled certificate one may call .PP .Vb 1 \& openssl cmp \-section insta,kur .Ve .PP using MAC-based protection with \s-1PBM\s0 or .PP .Vb 1 \& openssl cmp \-section insta,kur,signature .Ve .PP using signature-based protection. .PP In a similar way any previously enrolled certificate may be revoked by .PP .Vb 1 \& openssl cmp \-section insta,rr \-trusted insta.ca.crt .Ve .PP or .PP .Vb 1 \& openssl cmp \-section insta,rr,signature .Ve .PP Many more options can be given in the configuration file and/or on the command line. For instance, the \fB\-reqexts\fR \s-1CLI\s0 option may refer to a section in the configuration file defining X.509 extensions to use in certificate requests, such as \f(CW\*(C`v3_req\*(C'\fR in \fIopenssl/apps/openssl.cnf\fR: .PP .Vb 1 \& openssl cmp \-section insta,cr \-reqexts v3_req .Ve .SS "Certificate enrollment" .IX Subsection "Certificate enrollment" The following examples do not make use of a configuration file at first. They assume that a \s-1CMP\s0 server can be contacted on the local \s-1TCP\s0 port 80 and accepts requests under the alias \fI/pkix/\fR. .PP For enrolling its very first certificate the client generates a client key and sends an initial request message to the local \s-1CMP\s0 server using a pre-shared secret key for mutual authentication. In this example the client does not have the \s-1CA\s0 certificate yet, so we specify the name of the \s-1CA\s0 with the \fB\-recipient\fR option and save any \s-1CA\s0 certificates that we may receive in the \f(CW\*(C`capubs.pem\*(C'\fR file. .PP In below command line usage examples the \f(CW\*(C`\e\*(C'\fR at line ends is used just for formatting; each of the command invocations should be on a single line. .PP .Vb 5 \& openssl genrsa \-out cl_key.pem \& openssl cmp \-cmd ir \-server 127.0.0.1:80/pkix/ \-recipient "/CN=CMPserver" \e \& \-ref 1234 \-secret pass:1234\-5678 \e \& \-newkey cl_key.pem \-subject "/CN=MyName" \e \& \-cacertsout capubs.pem \-certout cl_cert.pem .Ve .SS "Certificate update" .IX Subsection "Certificate update" Then, when the client certificate and its related key pair needs to be updated, the client can send a key update request taking the certs in \f(CW\*(C`capubs.pem\*(C'\fR as trusted for authenticating the server and using the previous cert and key for its own authentication. Then it can start using the new cert and key. .PP .Vb 6 \& openssl genrsa \-out cl_key_new.pem \& openssl cmp \-cmd kur \-server 127.0.0.1:80/pkix/ \e \& \-trusted capubs.pem \e \& \-cert cl_cert.pem \-key cl_key.pem \e \& \-newkey cl_key_new.pem \-certout cl_cert.pem \& cp cl_key_new.pem cl_key.pem .Ve .PP This command sequence can be repeated as often as needed. .SS "Requesting information from \s-1CMP\s0 server" .IX Subsection "Requesting information from CMP server" Requesting \*(L"all relevant information\*(R" with an empty General Message. This prints information about all received \s-1ITAV\s0 \fBinfoType\fRs to stdout. .PP .Vb 2 \& openssl cmp \-cmd genm \-server 127.0.0.1/pkix/ \-recipient "/CN=CMPserver" \e \& \-ref 1234 \-secret pass:1234\-5678 .Ve .SS "Using a custom configuration file" .IX Subsection "Using a custom configuration file" For \s-1CMP\s0 client invocations, in particular for certificate enrollment, usually many parameters need to be set, which is tedious and error-prone to do on the command line. Therefore, the client offers the possibility to read options from sections of the OpenSSL config file, usually called \fIopenssl.cnf\fR. The values found there can still be extended and even overridden by any subsequently loaded sections and on the command line. .PP After including in the configuration file the following sections: .PP .Vb 8 \& [cmp] \& server = 127.0.0.1 \& path = pkix/ \& trusted = capubs.pem \& cert = cl_cert.pem \& key = cl_key.pem \& newkey = cl_key.pem \& certout = cl_cert.pem \& \& [init] \& recipient = "/CN=CMPserver" \& trusted = \& cert = \& key = \& ref = 1234 \& secret = pass:1234\-5678\-1234\-567 \& subject = "/CN=MyName" \& cacertsout = capubs.pem .Ve .PP the above enrollment transactions reduce to .PP .Vb 2 \& openssl cmp \-section cmp,init \& openssl cmp \-cmd kur \-newkey cl_key_new.pem .Ve .PP and the above transaction using a general message reduces to .PP .Vb 1 \& openssl cmp \-section cmp,init \-cmd genm .Ve .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBopenssl\-genrsa\fR\|(1), \fBopenssl\-ecparam\fR\|(1), \fBopenssl\-list\fR\|(1), \&\fBopenssl\-req\fR\|(1), \fBopenssl\-x509\fR\|(1), \fBx509v3_config\fR\|(5) .SH "HISTORY" .IX Header "HISTORY" The \fBcmp\fR application was added in OpenSSL 3.0. .PP The \fB\-engine option\fR was deprecated in OpenSSL 3.0. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2007\-2023 The OpenSSL Project Authors.
