PKI --EST(1) strongSwan PKI --EST(1) NAME pki --est - Enroll an X.509 certificate with an EST server SYNOPSIS pki --est ---url url [--label label] [--in file] --cacert file [--cert file|--certid hex --key file|--keyid hex] [--userpass username:password] [--interval time] [--maxpolltime time] [--outform encoding] [--debug level] pki --est --options file pki --est -h | --help DESCRIPTION This sub-command of pki(1) sends a PKCS#10 certificate request via HTTPS to a server using the Enrollment over Secure Transport (EST) Protocol (RFC 7030). After successful authorization which with manual authentication re- quires periodic polling by the enrollment client, the EST 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 private key can be requested, using the old certificate and the old key for automatic TLS client authentication with the EST 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 EST server. -l, --label label Label in the EST server path. -i, --in file PKCS#10 certificate request. If not given, the certificate request is read from STDIN. -C, --cacert file CA certificate in the trust chain used for EST TLS server signature verification or in the trust chain to verify the client certificate issued by the CA. Can be used multiple times. -c, --cert file Client certificate to be renewed. -X, --certid hex Smartcard or TPM 2.0 client certificate object handle. -k, --key file Client private key to be replaced. -x, --keyid hex Smartcard or TPM 2.0 client private key object handle. -p, --userpass username:password Optional username:password that may be used for HTTP basic authenti- cation. -t, --interval time Poll interval in seconds, defaults to 60s. This value might get overridden by the retry-after header in the HTTP 202 reply from the EST server. -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 est.opt file: --url https://pki.strongswan.org:8443 --cacert tlsca.crt --cacert tlsca-1.crt --cacert myca.crt --cacert myca-1.crt NOTE: For a successful HTTPS connection, trust must be established into the EST server certificate. The TLS trust chain including the root CA certifi- cate and optionally intermediate CA certificates must be given using multi- ple --cacert options. The --cacert option must also be used to be able to verify the received client certificate issued by the CA. This second trust chain might be iden- tical to the TLS trust chain (if the EST server is using a TLS server cer- tificate issued by its own CA) or might be totally different, e.g. if a Let's Encrypt EST server certificate is used. With the following command, an X.509 certificate signed by the intermediate CA is requested from an EST server based on a PKCS#10 certificate request: pki --options est.opt --in moonReq.der > moonCert.der negotiated TLS 1.3 using suite TLS_AES_256_GCM_SHA384 received TLS server certificate 'C=CH, O=strongSwan Project, CN=pki.strongswan.org' using certificate "C=CH, O=strongSwan Project, CN=pki.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 EST request pending, polling indefinitely every 300 seconds going to sleep for 300 seconds ...
