=head1 DESCRIPTION
These functions initialise an B<X509_STORE_CTX> structure for subsequent use
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
+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_set_chain() sets the additional certificate chain used by B<ctx>
-to B<sk>.
+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
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
+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_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
+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. X509_STORE_CTX_get_verify() obtains the current verify
+function being used.
-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_set_verify() works in the same way as for X509_STORE_CTX_set_verify()
+but sets the default verify function to be used by all X509_STORE_CTX objects
+created for this X509_STORE.
- X509_STORE_CTX ctx;
- X509_STORE_CTX_init(&ctx, store, cert, chain);
+A verify function is defined as an X509_STORE_CTX_verify type which has the
+following signature:
-this is B<not> recommended in new applications they should instead do:
+ int (*verify)(X509_STORE_CTX *);
- X509_STORE_CTX *ctx;
- ctx = X509_STORE_CTX_new();
- if (ctx == NULL)
- /* Bad error */
- X509_STORE_CTX_init(ctx, store, cert, chain);
+This function should receive the current X509_STORE_CTX as a parameter and
+return 1 on success or 0 on failure.

=head1 BUGS
X509_STORE_CTX_get0_param() returns a pointer to an B<X509_VERIFY_PARAM>
structure or B<NULL> if an error occurred.

used.
