L<foo|foo> is sub-optimal If the xref is the same as the title, which is what we do, then you only need L<foo>. This fixes all 1457 occurrences in 349 files. Approximately. (And pod used to need both.) Reviewed-by: Richard Levitte <levitte@openssl.org>

=head1 DESCRIPTION
|
|
|
|
These functions initialise an B<X509_STORE_CTX> structure for subsequent use
|
|
by X509_verify_cert().
|
|
|
|
X509_STORE_CTX_new() returns a newly initialised B<X509_STORE_CTX> structure.
|
|
|
|
X509_STORE_CTX_cleanup() internally cleans up an B<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 B<ctx>. After this call B<ctx>
|
|
is no longer valid.
|
|
If B<ctx> is NULL nothing is done.
|
|
|
|
X509_STORE_CTX_init() sets up B<ctx> for a subsequent verification operation.
|
|
It must be called before each call to X509_verify_cert(), i.e. a B<ctx> is only
|
|
good for one call to X509_verify_cert(); if you want to verify a second
|
|
certificate with the same B<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 B<store>, the end
|
|
entity certificate to be verified is set to B<x509> and a set of additional
|
|
certificates (which will be untrusted but may be used to build the chain) in
|
|
B<chain>. Any or all of the B<store>, B<x509> and B<chain> parameters can be
|
|
B<NULL>.
|
|
|
|
X509_STORE_CTX_trusted_stack() sets the set of trusted certificates of B<ctx>
|
|
to B<sk>. This is an alternative way of specifying trusted certificates
|
|
instead of using an B<X509_STORE>.
|
|
|
|
X509_STORE_CTX_set_cert() sets the certificate to be verified in B<ctx> to
|
|
B<x>.
|
|
|
|
X509_STORE_CTX_set_chain() sets the additional certificate chain used by B<ctx>
|
|
to B<sk>.
|
|
|
|
X509_STORE_CTX_set0_crls() sets a set of CRLs to use to aid certificate
|
|
verification to B<sk>. These CRLs will only be used if CRL verification is
|
|
enabled in the associated B<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 internal pointer
|
|
to the verification parameters associated with B<ctx>.
|
|
|
|
X509_STORE_CTX_set0_param() sets the internal verification parameter pointer
|
|
to B<param>. After this call B<param> should not be used.
|
|
|
|
X509_STORE_CTX_set_default() looks up and sets the default verification
|
|
method to B<name>. This uses the function X509_VERIFY_PARAM_lookup() to
|
|
find an appropriate set of parameters from B<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().
|
|
|
|
=head1 NOTES
|
|
|
|
The certificates and CRLs in a store are used internally and should B<not>
|
|
be freed up until after the associated B<X509_STORE_CTX> is freed. Legacy
|
|
applications might implicitly use an B<X509_STORE_CTX> like this:
|
|
|
|
X509_STORE_CTX ctx;
|
|
X509_STORE_CTX_init(&ctx, store, cert, chain);
|
|
|
|
this is B<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);
|
|
|
|
=head1 BUGS
|
|
|
|
The certificates and CRLs in a context are used internally and should B<not>
|
|
be freed up until after the associated B<X509_STORE_CTX> is freed. Copies
|
|
should be made or reference counts increased instead.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
X509_STORE_CTX_new() returns an newly allocates context or B<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 B<X509_VERIFY_PARAM>
|
|
structure or B<NULL> if an error occurred.

|
|
X509_STORE_CTX_cleanup(), X509_STORE_CTX_free(), X509_STORE_CTX_trusted_stack(),

|
|
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.
