NAME
pki --scep - Enroll an X.509 certificate with a SCEP server

[--password password] --ca-cert-enc file --ca-cert-sig file
[--cacert file] [--cert file --key file] [--cipher cipher]

pki --scep --options file
pki --scep -h | --help
DESCRIPTION
This sub-command of pki(1) sends a PKCS#10 certificate request in an
encrypted and signed PKCS#7 container via HTTP to a SCEP server using
the Simple Certificate Enrollment Protocol (RFC 8894). After successful
authorization which with manual authentication requires periodic
polling by the enrollment client, the SCEP server returns an X.509
certificate signed by the CA.
Before the expiry of the current certificate, a new client certificate
based on a fresh RSA private key can be requested, using the old
certificate and the old key for automatic authentication with the SCEP
server.
OPTIONS
-h, --help
Print usage information with a summary of the available options.
-v, --debug level
Set debug level, default: 1.
-+, --options file
Read command line options from file.
-u, --url url
URL of the SCEP server.
-i, --in file
RSA private key. If not given the key is read from STDIN.
-d, --dn distinguished-name
Subject distinguished name (DN). Required unless --cert is
given.
-a, --san subjectAltName
subjectAltName extension to include in request. Can be used
multiple times.
-P, --profile profile
Certificate profile name to be included in the certificate
request. Can be any UTF8 string. Supported e.g. by the openxpki
SCEP server with profiles (pc-client, tls-server, etc.) that are
translated into corresponding Extended Key Usage (EKU) flags in
-s, --cacert-sig file
CA certificate for signature verification
-C, --cacert file
Additional CA certificate in the trust chain used for signature
verification. Can be used multiple times.
-c, --cert file
Client certificate to be renewed.
-k, --key file
Client RSA private key to be replaced.
-E, --cipher cipher
Cipher used for symmetric encryption. Either aes (the default)
or des3.
-g, --digest digest
Digest to use for signature creation. One of sha256 (the
default), sha384, sha512, or sha1.
-R, --rsa-padding padding
Padding to use for RSA signatures. Either pkcs1 (the default) or
pss.
-t, --interval time
Poll interval in seconds, defaults to 60s.
-m, --maxpolltime time
Maximum poll time in seconds, defaults to 0 which means
unlimited polling.
-f, --outform encoding
Encoding of the created certificate file. Either der (ASN.1 DER)
or pem (Base64 PEM), defaults to der.
EXAMPLES
To save some typing work the following command line options are stored
in a scep.opt file:
--url http://pki.strongswan.org:8080/scep
--cacert-enc myra.crt
--cacert-sig myca-1.crt
--cacert myca.crt
With the following command, an X.509 certificate signed by the
intermediate CA is requested from a SCEP server:
pki --options scep.opt --in moonKey.der --san "moon.strongswan.org" \
--dn "C=CH, O=strongSec GmbH, CN=moon.strongswan.org" > moonCert.der
transaction ID: 4DFCF31CB18A9B5333CCEC6F99CF230E4524E334
using certificate "C=CH, O=strongSwan Project, CN=SCEP RA"
using trusted intermediate ca certificate "C=CH, O=strongSwan Project, CN=strongSwan Issuing CA"
using trusted ca certificate "C=CH, O=strongSwan Project, CN=strongSwan Root CA"
reached self-signed root ca with a path length of 1
SCEP request pending, polling indefinitely every 60 seconds
going to sleep for 60 seconds
using trusted ca certificate "C=CH, O=strongSwan Project, CN=strongSwan Root CA"
reached self-signed root ca with a path length of 1
Issued certificate is trusted, valid from Aug 22 18:56:23 2022 until Aug 22 18:56:23 2023 (currently valid)
A certificate about to expire can be renewed with the command:
pki --options scep.opt --in moonNewKey.der --san "moon.strongswan.org" \
--dn "C=CH, O=strongSec GmbH, CN=moon.strongswan.org" \
--cert moonCert.der --key moonKey.der > moonNewCert.der
transaction ID: A9A63D028CC439F68452D125C4DBA025E67DBA95
using certificate "C=CH, O=strongSwan Project, CN=SCEP RA"
using trusted intermediate ca certificate "C=CH, O=strongSwan Project, CN=strongSwan Issuing CA"
using trusted ca certificate "C=CH, O=strongSwan Project, CN=strongSwan Root CA"
reached self-signed root ca with a path length of 1
Issued certificate "C=CH, O=strongSwan Project, CN=moon.strongswan.org"
serial: 1f:ff:b2:78:43:a2:9d:85:00:38
using certificate "C=CH, O=strongSwan Project, CN=moon.strongswan.org"
using trusted intermediate ca certificate "C=CH, O=strongSwan Project, CN=strongSwan Issuing CA"
using trusted ca certificate "C=CH, O=strongSwan Project, CN=strongSwan Root CA"
reached self-signed root ca with a path length of 1
Issued certificate is trusted, valid from Jul 20 15:05:33 2023 until Jul 20 15:05:33 2024 (currently valid)
