=head1 DESCRIPTION
|
|
|
|
X509_STORE_set_verify_cb() sets the verification callback of B<ctx> to
|
|
B<verify_cb> overwriting the previous callback.
|
|
The callback assigned with this function becomes a default for the one
|
|
that can be assigned directly to the corresponding B<X509_STORE_CTX>,
|
|
please see L<X509_STORE_CTX_set_verify_cb(3)> for further information.
|
|
|
|
X509_STORE_set_verify() sets the final chain verification function for
|
|
B<ctx> to B<verify>.
|
|
Its purpose is to go through the chain of certificates and check that
|
|
all signatures are valid and that the current time is within the
|
|
limits of each certificate's first and last validity time.
|
|
The final chain verification functions must return 0 on failure and 1
|
|
on success.
|
|
I<If no chain verification function is provided, the internal default
|
|
function will be used instead.>
|
|
|
|
X509_STORE_set_get_issuer() sets the function to get the issuer
|
|
certificate that verifies the given certificate B<x>.
|
|
When found, the issuer certificate must be assigned to B<*issuer>.
|
|
This function must return 0 on failure and 1 on success.
|
|
I<If no function to get the issuer is provided, the internal default
|
|
function will be used instead.>
|
|
|
|
X509_STORE_set_check_issued() sets the function to check that a given
|
|
certificate B<x> is issued with the issuer certificate B<issuer>.
|
|
This function must return 0 on failure (among others if B<x> hasn't
|
|
been issued with B<issuer>) and 1 on success.
|
|
I<If no function to get the issuer is provided, the internal default
|
|
function will be used instead.>
|
|
|
|
X509_STORE_set_check_revocation() sets the revocation checking
|
|
function.
|
|
Its purpose is to look through the final chain and check the
|
|
revocation status for each certificate.
|
|
It must return 0 on failure and 1 on success.
|
|
I<If no function to get the issuer is provided, the internal default
|
|
function will be used instead.>
|
|
|
|
X509_STORE_set_get_crl() sets the function to get the crl for a given
|
|
certificate B<x>.
|
|
When found, the crl must be assigned to B<*crl>.
|
|
This function must return 0 on failure and 1 on success.
|
|
I<If no function to get the issuer is provided, the internal default
|
|
function will be used instead.>
|
|
|
|
X509_STORE_set_check_crl() sets the function to check the validity of
|
|
the given B<crl>.
|
|
This function must return 0 on failure and 1 on success.
|
|
I<If no function to get the issuer is provided, the internal default
|
|
function will be used instead.>
|
|
|
|
X509_STORE_set_cert_crl() sets the function to check the revocation
|
|
status of the given certificate B<x> against the given B<crl>.
|
|
This function must return 0 on failure and 1 on success.
|
|
I<If no function to get the issuer is provided, the internal default
|
|
function will be used instead.>
|
|
|
|
X509_STORE_set_check_policy() sets the function to check the policies
|
|
of all the certificates in the final chain..
|
|
This function must return 0 on failure and 1 on success.
|
|
I<If no function to get the issuer is provided, the internal default
|
|
function will be used instead.>
|
|
|
|
X509_STORE_set_lookup_certs() and X509_STORE_set_lookup_crls() set the
|
|
functions to look up all the certs or all the CRLs that match the
|
|
given name B<nm>.
|
|
These functions return NULL on failure and a pointer to a stack of
|
|
certificates (B<X509>) or to a stack of CRLs (B<X509_CRL>) on
|
|
success.
|
|
I<If no function to get the issuer is provided, the internal default
|
|
function will be used instead.>
|
|
|
|
X509_STORE_set_cleanup() sets the final cleanup function, which is
|
|
called when the context (B<X509_STORE_CTX>) is being torn down.
|
|
This function doesn't return any value.
|
|
I<If no function to get the issuer is provided, the internal default
|
|
function will be used instead.>

|
|
|
X509_STORE_set_verify_cb_func(), X509_STORE_set_verify_func() and
|
|
X509_STORE_set_lookup_crls_cb() are aliases for
|
|
X509_STORE_set_verify_cb(), X509_STORE_set_verify() and
|
|
X509_STORE_set_lookup_crls, available as macros for backward
|
|
compatibility.
|
|
|
|
=head1 NOTES
|
|
|
|
All the callbacks from a B<X509_STORE> are inherited by the
|
|
corresponding B<X509_STORE_CTX> structure when it is initialized.
|
|
See L<X509_STORE_CTX_set_verify_cb(3)> for further details.
