DESCRIPTION
X509_STORE_set_verify_cb() sets the verification callback of xs to
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 X509_STORE_CTX, please see
X509_STORE_CTX_set_verify_cb(3) for further information.
X509_STORE_set_verify() sets the final chain verification function for
xs to 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. If no chain verification function is provided, the
internal default function will be used instead.
X509_STORE_CTX_get1_issuer() tries to find a certificate from the store
component of ctx that has a subject name matching the issuer name of x
and is accepted by the check_issued function in ctx. On success it
assigns to *issuer the first match that has a suitable validity period
or otherwise has the latest expiration date of all matching
certificates. If the function returns 1 the caller is responsible for
freeing *issuer. Note that this search does not support backtracking.
X509_STORE_set_get_issuer() sets the function get_issuer that is used
to get the "best" candidate issuer certificate of the given certificate
x. When such a certificate is found, get_issuer must up-ref and assign
it to *issuer and then return 1. Otherwise get_issuer must return 0 if
not found and -1 (or 0) on failure. If X509_STORE_set_get_issuer() is
not used or get_issuer is NULL then X509_STORE_CTX_get1_issuer() is
used as the default implementation.
X509_STORE_set_check_issued() sets the function to check that a given
certificate x is issued by the issuer certificate issuer. This
function must return 0 on failure (among others if x hasn't been issued
with issuer) and 1 on success. 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. 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 x. When found, the crl must be assigned to *crl. This
function must return 0 on failure and 1 on success. 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 crl. This function must return 0 on failure and 1 on
success. 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 x against the given crl. This function
must return 0 on failure and 1 on success. 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. 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 nm. These functions return NULL on failure and a pointer to a
stack of certificates (X509) or to a stack of CRLs (X509_CRL) on
success. 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 (X509_STORE_CTX) is being torn down. This
function doesn't return any value. If no function to get the issuer is
provided, the internal default function will be used instead.
X509_STORE_get_verify_cb(), X509_STORE_CTX_get_verify(),
X509_STORE_get_get_issuer(), X509_STORE_get_check_issued(),
X509_STORE_get_check_revocation(), X509_STORE_get_get_crl(),
X509_STORE_get_check_crl(), X509_STORE_set_verify(),
X509_STORE_set_get_issuer(), X509_STORE_get_cert_crl(),
X509_STORE_get_check_policy(), X509_STORE_get_lookup_certs(),
X509_STORE_get_lookup_crls() and X509_STORE_get_cleanup() all return
the function pointer assigned with X509_STORE_set_check_issued(),
X509_STORE_set_check_revocation(), X509_STORE_set_get_crl(),
X509_STORE_set_check_crl(), X509_STORE_set_cert_crl(),
X509_STORE_set_check_policy(), X509_STORE_set_lookup_certs(),
X509_STORE_set_lookup_crls() and X509_STORE_set_cleanup(), or NULL if
no assignment has been made.
X509_STORE_set_verify_cb_func(3), 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.
NOTES
All the callbacks from a X509_STORE are inherited by the corresponding
X509_STORE_CTX structure when it is initialized. See
X509_STORE_CTX_set_verify_cb(3) for further details.
BUGS
The macro version of this function was the only one available before
OpenSSL 1.0.0.
RETURN VALUES
The X509_STORE_set_*() functions do not return a value.
The X509_STORE_get_*() functions return a pointer of the appropriate
function type.
X509_STORE_CTX_get1_issuer() returns 1 if a suitable certificate is
found, 0 if not found, -1 on other error.
