43 void X509_STORE_CTX_set_verify(X509_STORE_CTX *ctx, X509_STORE_CTX_verify_fn verify);
44
46 These functions initialise an X509_STORE_CTX structure for subsequent
47 use by X509_verify_cert().
48
49 X509_STORE_CTX_new() returns a newly initialised X509_STORE_CTX
50 structure.
51
52 X509_STORE_CTX_cleanup() internally cleans up an X509_STORE_CTX
53 structure. The context can then be reused with an new call to
54 X509_STORE_CTX_init().
55
56 X509_STORE_CTX_free() completely frees up ctx. After this call ctx is
57 no longer valid. If ctx is NULL nothing is done.
58
59 X509_STORE_CTX_init() sets up ctx for a subsequent verification
60 operation. It must be called before each call to X509_verify_cert(),
61 i.e. a ctx is only good for one call to X509_verify_cert(); if you want
62 to verify a second certificate with the same ctx then you must call
63 X509_STORE_CTX_cleanup() and then X509_STORE_CTX_init() again before
64 the second call to X509_verify_cert(). The trusted certificate store is
65 set to store, the end entity certificate to be verified is set to x509
66 and a set of additional certificates (which will be untrusted but may
67 be used to build the chain) in chain. Any or all of the store, x509 and
68 chain parameters can be NULL.
69
70 X509_STORE_CTX_set0_trusted_stack() sets the set of trusted
71 certificates of ctx to sk. This is an alternative way of specifying
72 trusted certificates instead of using an X509_STORE.
73
74 X509_STORE_CTX_set_cert() sets the certificate to be verified in ctx to
75 x.
76
77 X509_STORE_CTX_set0_verified_chain() sets the validated chain used by
78 ctx to be chain. Ownership of the chain is transferred to ctx and
79 should not be free'd by the caller. X509_STORE_CTX_get0_chain()
80 returns a the internal pointer used by the ctx that contains the
81 validated chain.
82
83 X509_STORE_CTX_set0_crls() sets a set of CRLs to use to aid certificate
84 verification to sk. These CRLs will only be used if CRL verification is
85 enabled in the associated X509_VERIFY_PARAM structure. This might be
86 used where additional "useful" CRLs are supplied as part of a protocol,
87 for example in a PKCS#7 structure.
88
89 X509_STORE_CTX_get0_param() retrieves an internal pointer to the
90 verification parameters associated with ctx.
91
92 X509_STORE_CTX_get0_untrusted() retrieves an internal pointer to the
93 stack of untrusted certificates associated with ctx.
94
95 X509_STORE_CTX_set0_untrusted() sets the internal point to the stack of
96 untrusted certificates associated with ctx to sk.
97
98 X509_STORE_CTX_set0_param() sets the internal verification parameter
99 pointer to param. After this call param should not be used.
100
101 X509_STORE_CTX_set_default() looks up and sets the default verification
102 method to name. This uses the function X509_VERIFY_PARAM_lookup() to
103 find an appropriate set of parameters from name.
104
105 X509_STORE_CTX_get_num_untrusted() returns the number of untrusted
106 certificates that were used in building the chain following a call to
107 X509_verify_cert().
108
109 X509_STORE_CTX_set_verify() provides the capability for overriding the
110 default verify function. This function is responsible for verifying
111 chain signatures and expiration times.
112
113 A verify function is defined as an X509_STORE_CTX_verify type which has
114 the following signature:
115
116 int (*verify)(X509_STORE_CTX *);
117
118 This function should receive the current X509_STORE_CTX as a parameter
119 and return 1 on success or 0 on failure.
120
122 The certificates and CRLs in a store are used internally and should not
123 be freed up until after the associated X509_STORE_CTX is freed.
124
126 The certificates and CRLs in a context are used internally and should
127 not be freed up until after the associated X509_STORE_CTX is freed.
128 Copies should be made or reference counts increased instead.
129
131 X509_STORE_CTX_new() returns an newly allocates context or NULL is an
132 error occurred.
133
134 X509_STORE_CTX_init() returns 1 for success or 0 if an error occurred.
135
136 X509_STORE_CTX_get0_param() returns a pointer to an X509_VERIFY_PARAM
137 structure or NULL if an error occurred.
138
139 X509_STORE_CTX_cleanup(), X509_STORE_CTX_free(),
140 X509_STORE_CTX_set0_trusted_stack(), X509_STORE_CTX_set_cert(),
141 X509_STORE_CTX_set0_crls() and X509_STORE_CTX_set0_param() do not
142 return values.
143
144 X509_STORE_CTX_set_default() returns 1 for success or 0 if an error
145 occurred.
146
147 X509_STORE_CTX_get_num_untrusted() returns the number of untrusted
148 certificates used.
