       pki - Simple public key infrastructure (PKI) management tool

       pki command [option ...]

       pki -h | --help

       pki  is	a  suite  of commands that allow you to manage a simple public key infrastructure

       Generate RSA and ECDSA key pairs, create PKCS#10 certificate requests  containing  subjec-
       tAltNames,  create X.509 self-signed end-entity and root CA certificates, issue end-entity
       and intermediate CA certificates signed by the private key of a CA and containing  subjec-
       tAltNames, CRL distribution points and URIs of OCSP servers. You can also extract raw pub-
       lic keys from private keys, certificate requests and certificates and compute two kinds of
       SHA-1-based key IDs.

       -h, --help
	      Prints usage information and a short summary of the available commands.

       -g, --gen
	      Generate a new private key.

       -s, --self
	      Create a self-signed certificate.

       -i, --issue
	      Issue a certificate using a CA certificate and key.

       -c, --signcrl
	      Issue a CRL using a CA certificate and key.

       -r, --req
	      Create a PKCS#10 certificate request.

       -7, --pkcs7
	      Provides PKCS#7 wrap/unwrap functions.

       -k, --keyid
	      Calculate key identifiers of a key or certificate.

       -a, --print
	      Print a credential (key, certificate etc.) in human readable form.

       -p, --pub
	      Extract a public key from a private key or certificate.

       -v, --verify
	      Verify a certificate using a CA certificate.

   Generating a CA Certificate
       The  first step is to generate a private key using the --gen command. By default this gen-
       erates a 2048-bit RSA key.

	 pki --gen > ca_key.der

       This key is used to create the self-signed CA certificate, using the --self  command.  The
       distinguished name should be adjusted to your needs.

	 pki --self --ca --in ca_key.der \
	     --dn "C=CH, O=strongSwan, CN=strongSwan CA" > ca_cert.der

   Generating End-Entity Certificates
       With  the  root	CA  certificate  and  key at hand end-entity certificates for clients and
       servers can be issued. Similarly intermediate CA certificates can be issued, which in turn
       can  issue other certificates.  To generate a certificate for a server, we start by gener-
       ating a private key.

	 pki --gen > server_key.der

       The public key will be included in the certificate so lets extract that from  the  private

	 pki --pub --in server_key.der > server_pub.der

       The following command will use the CA certificate and private key to issue the certificate
       for this server. Adjust the distinguished name,	subjectAltName(s)  and	flags  as  needed
       (check pki --issue(8) for more options).

	 pki --issue --in server_pub.der --cacert ca_cert.der \
	     --cakey ca_key.der --dn "C=CH, O=strongSwan, CN=VPN Server" \
	     --san vpn.strongswan.org --flag serverAuth > server_cert.der

       Instead	of  storing  the  public  key in a separate file, the output of --pub may also be
       piped directly into the above command.

   Generating Certificate Revocation Lists (CRL)
       If end-entity certificates have to be revoked, CRLs may be generated using  the	--signcrl

	 pki --signcrl --cacert ca_cert.der --cakey ca_key.der \
	     --reason superseded --cert server_cert.der > crl.der

       The  certificate given with --cacert must be either a CA certificate or a certificate with
       the crlSign extended key usage (--flag crlSign). URIs to CRLs may be  included  in  issued
       certificates with the --crl option.

       pki --gen(1),	 pki --self(1),     pki --issue(1),    pki --signcrl(1),    pki --req(1),
       pki --pkcs7(1), pki --keyid(1), pki --print(1), pki --pub(1), pki --verify(1)
