Untrusted objects should not be added in this way. .Pp .Fn X509_STORE_get_ex_new_index , .Fn X509_STORE_set_ex_data , and .Fn X509_STORE_get_ex_data handle application specific data in .Vt X509_STORE objects. Their usage is identical to that of .Xr RSA_get_ex_new_index 3 , .Xr RSA_set_ex_data 3 , and .Xr RSA_get_ex_data 3 . .Fn X509_STORE_get_ex_new_index is implemented as a macro. .Sh RETURN VALUES .Fn X509_STORE_set1_param , .Fn X509_STORE_set_purpose , .Fn X509_STORE_set_trust , and .Fn X509_STORE_set_ex_data return 1 for success or 0 for failure. .Pp .Fn X509_STORE_set_flags and .Fn X509_STORE_set_depth always return 1, indicating success. .Pp .Fn X509_STORE_add_cert and .Fn X509_STORE_add_crl return 1 for success or 0 for failure. For example, they fail if .Fa x or .Fa crl is a .Dv NULL pointer, if a certificate with the same subject name as .Fa x or a revocation list with the same issuer name as .Fa crl are already contained in the .Fa store , or if memory allocation fails. .Pp .Fn X509_STORE_get0_param returns an internal pointer to the verification parameter object contained in the .Fa store . The returned pointer must not be freed by the calling application. .Pp .Fn X509_STORE_get1_objects returns a newly allocated stack containing the certificates, revocation lists, and private keys in .Fa store , as well as cached objects added by .Xr X509_LOOKUP_hash_dir 3 . The caller must release the result with .Xr sk_pop_free 3 and .Xr X509_OBJECT_free 3 when done. .Pp .Fn X509_STORE_get0_objects is a deprecated function returning an internal pointer to the stack of certificates, revocation lists, and private keys contained in .Fa store . The returned pointer must not be modified or freed by the calling application. This function is not thread-safe. If .Fa store is shared across multiple threads, callers cannot safely inspect the result of this function, because another thread may have concurrently added to it. In particular, .Xr X509_LOOKUP_hash_dir 3 treats this list as a cache and may add to it in the course of certificate verification. .Pp .Fn X509_STORE_get_ex_new_index returns a new index or \-1 on failure. .Pp .Fn X509_STORE_get_ex_data returns the application data or .Dv NULL on failure. .Sh SEE ALSO .Xr RSA_get_ex_new_index 3 , .Xr SSL_set1_param 3 , .Xr X509_LOOKUP_new 3 , .Xr X509_OBJECT_get0_X509 3 , .Xr X509_STORE_CTX_set0_param 3 , .Xr X509_STORE_load_locations 3 , .Xr X509_STORE_new 3 , .Xr X509_VERIFY_PARAM_new 3 , .Xr X509_VERIFY_PARAM_set_flags 3 .Sh HISTORY .Fn X509_STORE_add_cert first appeared in SSLeay 0.8.0. .Fn X509_STORE_add_crl first appeared in SSLeay 0.9.0.
