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 After this call ctx is no longer valid.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_XTORE_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.
