h1. ipsec.conf: ca <name>

h1. ca <name>

*ca* sections are *optional sections* that can be used to assign special parameters to a Certification Authority (CA).

Because the daemon automatically imports CA certificates from [[IpsecDirectoryCacerts|/etc/ipsec.d/cacerts]], there is no need to explicitly

add them with a CA section, unless you want to assign special parameters (like a CRL) to a CA.

h2. Parameters

_also = <name>_

p((. includes ca section _<name>_.  Some aspects of this changed with version:5.2.0 (refer to [[IpsecConf#Reusing-Existing-Parameters]] for details).

_auto = *ignore* | add_

_cacert = <path>_

p((. defines a path to the CA certificate either relative to [[IpsecDirectoryCacerts|/etc/ipsec.d/cacerts]] or as an absolute path.

p((. Since [[5.0.2]] a value of the form _%smartcard[<slot nr>[@<module>]]:<keyid>_ defines a specific CA certificate

     to load from a PKCS#11 backend for this CA. See [[PinSecret|ipsec.secrets]] for details about smartcard definitions

_crluri = <uri>_

p((. defines a CRL distribution point (ldap, http, or file URI).

_crluri1_

p((. synonym for _crluri_.

_crluri2 = <uri>_

p((. defines an alternative CRL distribution point (ldap, http, or file URI).

_ocspuri = <uri>_

p((. defines an OCSP URI.

_ocspuri1_

p((. synonym for _ocspuri_.

_ocspuri2 = <uri>_

p((. defines an alternative OCSP URI. Only used by the charon daemon (since 5.0.0 also for IKEv1).

_certuribase = <uri>_

p((. defines the base URI for the [[HashAndUrl|Hash and URL]] feature supported by IKEv2.

     Instead of exchanging complete certificates, IKEv2 allows to send an URI

     that resolves to the DER encoded certificate. The certificate URIs are built

     by appending the SHA1 hash of the DER encoded certificates to this base URI.

h2. Old options (before 5.0.0)

_ldaphost = <hostname>_

p((. defines an ldap host. Only used by the IKEv1 daemon pluto.
