25=head1 DESCRIPTION
26
27SSL_CTX_set0_verify_cert_store() and SSL_CTX_set1_verify_cert_store()
28set the certificate store used for certificate verification to B<st>.
29
30SSL_CTX_set0_chain_cert_store() and SSL_CTX_set1_chain_cert_store()
31set the certificate store used for certificate chain building to B<st>.
32
33SSL_set0_verify_cert_store(), SSL_set1_verify_cert_store(),
34SSL_set0_chain_cert_store() and SSL_set1_chain_cert_store() are similar
35except they apply to SSL structure B<ssl>.
36
37All these functions are implemented as macros. Those containing a B<1>
38increment the reference count of the supplied store so it must
39be freed at some point after the operation. Those containing a B<0> do
40not increment reference counts and the supplied store B<MUST NOT> be freed
41after the operation.
42
43=head1 NOTES
44
45The stores pointers associated with an SSL_CTX structure are copied to any SSL
46structures when SSL_new() is called. As a result SSL structures will not be
47affected if the parent SSL_CTX store pointer is set to a new value.
48
49The verification store is used to verify the certificate chain sent by the
50peer: that is an SSL/TLS client will use the verification store to verify
51the server's certificate chain and a SSL/TLS server will use it to verify
52any client certificate chain.
53
54The chain store is used to build the certificate chain.
55
56If the mode B<SSL_MODE_NO_AUTO_CHAIN> is set or a certificate chain is
57configured already (for example using the functions such as 
58L<SSL_CTX_add1_chain_cert(3)|SSL_CTX_add1_chain_cert(3)> or
59L<SSL_CTX_add_extra_chain_cert(3)|SSL_CTX_add_extra_chain_cert(3)>) then
60automatic chain building is disabled.
61
62If the mode B<SSL_MODE_NO_AUTO_CHAIN> is set then automatic chain building
63is disabled.
64
65If the chain or the verification store is not set then the store associated
66with the parent SSL_CTX is used instead to retain compatibility with previous
67versions of OpenSSL.

70
71All these functions return 1 for success and 0 for failure.
