Enhance find-doc-nits to be better about finding typedefs for callback functions. Fix all nits it now finds. Added some new typedef names to ssl.h some of which were documented but did not exist Reviewed-by: Richard Levitte <levitte@openssl.org> (Merged from https://github.com/openssl/openssl/pull/2151)

=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is no longer valid.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_set0_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_set0_verified_chain() sets the validated chain used
|
|
by B<ctx> to be B<chain>.
|
|
Ownership of the chain is transferred to B<ctx> and should not be
|
|
free'd by the caller.
|
|
X509_STORE_CTX_get0_chain() returns a the internal pointer used by the
|
|
B<ctx> that contains the validated chain.
|
|
|
|
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_STORE_CTX_get0_param() retrieves an internal pointer
|
|
to the verification parameters associated with B<ctx>.
|
|
|
|
X509_STORE_CTX_get0_untrusted() retrieves an internal pointer to the
|
|
stack of untrusted certificates associated with B<ctx>.
|
|
|
|
X509_STORE_CTX_set0_untrusted() sets the internal point to the stack
|
|
of untrusted certificates associated with B<ctx> to B<sk>.
|
|
|
|
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().
|
|
|
|
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.
|
|
|
|
=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.
|
|
|
|
=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_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.
