These functions initialise an X509_STORE_CTX structure for subsequent use by X509_verify_cert().
X509_STORE_CTX_new()
returns a newly initialised X509_STORE_CTX structure.
X509_STORE_CTX_cleanup()
internally cleans up an X509_STORE_CTX structure.
The context can then be reused with an new call to X509_STORE_CTX_init().
X509_STORE_CTX_free()
completely frees up ctx. After this call ctx
is no longer valid.
If ctx is NULL nothing is done.
X509_STORE_CTX_init()
sets up ctx for a subsequent verification operation.
It must be called before each call to X509_verify_cert(), i.e. a ctx is only
good for one call to X509_verify_cert(); if you want to verify a second
certificate with the same ctx then you must call X509_STORE_CTX_cleanup()
and then X509_STORE_CTX_init()
again before the second call to
X509_verify_cert(). The trusted certificate store is set to store, the end
entity certificate to be verified is set to x509 and a set of additional
certificates (which will be untrusted but may be used to build the chain) in
chain. Any or all of the store, x509 and chain parameters can be
NULL.
X509_STORE_CTX_set0_trusted_stack()
sets the set of trusted certificates of
ctx to sk. This is an alternative way of specifying trusted certificates
instead of using an X509_STORE.
X509_STORE_CTX_set_cert()
sets the certificate to be verified in ctx to
x.
X509_STORE_CTX_set0_verified_chain()
sets the validated chain used
by ctx to be chain.
Ownership of the chain is transferred to ctx and should not be
free'd by the caller.
X509_STORE_CTX_get0_chain()
returns a the internal pointer used by the
ctx that contains the validated chain.
X509_STORE_CTX_set0_crls()
sets a set of CRLs to use to aid certificate
verification to sk. These CRLs will only be used if CRL verification is
enabled in the associated X509_VERIFY_PARAM structure. This might be
used where additional ``useful'' CRLs are supplied as part of a protocol,
for example in a PKCS#7 structure.
X509_STORE_CTX_get0_param()
retrieves an internal pointer
to the verification parameters associated with ctx.
X509_STORE_CTX_get0_untrusted()
retrieves an internal pointer to the
stack of untrusted certificates associated with ctx.
X509_STORE_CTX_set0_untrusted()
sets the internal point to the stack
of untrusted certificates associated with ctx to sk.
X509_STORE_CTX_set0_param()
sets the internal verification parameter pointer
to param. After this call param should not be used.
X509_STORE_CTX_set_default()
looks up and sets the default verification
method to name. This uses the function X509_VERIFY_PARAM_lookup()
to
find an appropriate set of parameters from name.
X509_STORE_CTX_get_num_untrusted()
returns the number of untrusted certificates
that were used in building the chain following a call to X509_verify_cert().
X509_STORE_CTX_set_verify()
provides the capability for overriding the default
verify function. This function is responsible for verifying chain signatures and
expiration times.
A verify function is defined as an X509_STORE_CTX_verify type which has the following signature:
int (*verify)(X509_STORE_CTX *);
This function should receive the current X509_STORE_CTX as a parameter and return 1 on success or 0 on failure.
The certificates and CRLs in a store are used internally and should not be freed up until after the associated X509_STORE_CTX is freed.
The certificates and CRLs in a context are used internally and should not be freed up until after the associated X509_STORE_CTX is freed. Copies should be made or reference counts increased instead.
X509_STORE_CTX_new()
returns an newly allocates context or NULL is an
error occurred.
X509_STORE_CTX_init()
returns 1 for success or 0 if an error occurred.
X509_STORE_CTX_get0_param()
returns a pointer to an X509_VERIFY_PARAM
structure or NULL if an error occurred.
X509_STORE_CTX_cleanup(), X509_STORE_CTX_free(),
X509_STORE_CTX_set0_trusted_stack(),
X509_STORE_CTX_set_cert(),
X509_STORE_CTX_set0_crls()
and X509_STORE_CTX_set0_param()
do not return
values.
X509_STORE_CTX_set_default()
returns 1 for success or 0 if an error occurred.
X509_STORE_CTX_get_num_untrusted()
returns the number of untrusted certificates
used.
