DESCRIPTION
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no longer valid.
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_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 vertified in ctx
to x.
X509_STORE_CTX_set_chain() sets the additional certificate chain used
by ctx to sk.
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_VERIFY_PARAM *X509_STORE_CTX_get0_param() retrieves an intenal
pointer to the verification parameters associated with ctx.
X509_STORE_CTX_set0_param() sets the intenal 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.

NOTES
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. Legacy
applications might implicitly use an X509_STORE_CTX like this:
X509_STORE_CTX ctx;
X509_STORE_CTX_init(&ctx, store, cert, chain);
this is not recommended in new applications they should instead do:
X509_STORE_CTX *ctx;
ctx = X509_STORE_CTX_new();
if (ctx == NULL)
/* Bad error */
X509_STORE_CTX_init(ctx, store, cert, chain);

BUGS
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.
RETURN VALUES
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_trusted_stack(), X509_STORE_CTX_set_cert(),
X509_STORE_CTX_set_chain(), 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.
