The context can then be reused with an new call to \fBX509_STORE_CTX_init()\fR. .PP \&\fBX509_STORE_CTX_free()\fR completely frees up \fBctx\fR. After this call \fBctx\fR is no longer valid. .PP \&\fBX509_STORE_CTX_init()\fR sets up \fBctx\fR for a subsequent verification operation. It must be called before each call to \fBX509_verify_cert()\fR, i.e. a \fBctx\fR is only good for one call to \fBX509_verify_cert()\fR; if you want to verify a second certificate with the same \fBctx\fR then you must call \fBX509_STORE_CTX_cleanup()\fR and then \fBX509_STORE_CTX_init()\fR again before the second call to \&\fBX509_verify_cert()\fR. The trusted certificate store is set to \fBstore\fR, the end entity certificate to be verified is set to \fBx509\fR and a set of additional certificates (which will be untrusted but may be used to build the chain) in \&\fBchain\fR. Any or all of the \fBstore\fR, \fBx509\fR and \fBchain\fR parameters can be \&\fB\s-1NULL\s0\fR. .PP \&\fBX509_STORE_CTX_trusted_stack()\fR sets the set of trusted certificates of \fBctx\fR to \fBsk\fR. This is an alternative way of specifying trusted certificates instead of using an \fBX509_STORE\fR. .PP \&\fBX509_STORE_CTX_set_cert()\fR sets the certificate to be vertified in \fBctx\fR to \&\fBx\fR. .PP \&\fBX509_STORE_CTX_set_chain()\fR sets the additional certificate chain used by \fBctx\fR to \fBsk\fR. .PP \&\fBX509_STORE_CTX_set0_crls()\fR sets a set of CRLs to use to aid certificate verification to \fBsk\fR. These CRLs will only be used if \s-1CRL\s0 verification is enabled in the associated \fBX509_VERIFY_PARAM\fR structure. This might be used where additional \*(L"useful\*(R" CRLs are supplied as part of a protocol, for example in a PKCS#7 structure. .PP X509_VERIFY_PARAM *\fBX509_STORE_CTX_get0_param()\fR retrieves an intenal pointer to the verification parameters associated with \fBctx\fR. .PP \&\fBX509_STORE_CTX_set0_param()\fR sets the intenal verification parameter pointer to \fBparam\fR. After this call \fBparam\fR should not be used. .PP \&\fBX509_STORE_CTX_set_default()\fR looks up and sets the default verification method to \fBname\fR. This uses the function \fBX509_VERIFY_PARAM_lookup()\fR to find an appropriate set of parameters from \fBname\fR. .SH "NOTES" .IX Header "NOTES" The certificates and CRLs in a store are used internally and should \fBnot\fR be freed up until after the associated \fBX509_STORE_CTX\fR is freed. Legacy applications might implicitly use an \fBX509_STORE_CTX\fR like this: .PP .Vb 2 \& X509_STORE_CTX ctx; \& X509_STORE_CTX_init(&ctx, store, cert, chain); .Ve .PP this is \fBnot\fR recommended in new applications they should instead do: .PP .Vb 5 \& X509_STORE_CTX *ctx; \& ctx = X509_STORE_CTX_new(); \& if (ctx == NULL) \& /* Bad error */ \& X509_STORE_CTX_init(ctx, store, cert, chain); .Ve .SH "BUGS" .IX Header "BUGS" The certificates and CRLs in a context are used internally and should \fBnot\fR be freed up until after the associated \fBX509_STORE_CTX\fR is freed. Copies should be made or reference counts increased instead. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBX509_STORE_CTX_new()\fR returns an newly allocates context or \fB\s-1NULL\s0\fR is an error occurred. .PP \&\fBX509_STORE_CTX_init()\fR returns 1 for success or 0 if an error occurred. .PP \&\fBX509_STORE_CTX_get0_param()\fR returns a pointer to an \fBX509_VERIFY_PARAM\fR structure or \fB\s-1NULL\s0\fR if an error occurred. .PP \&\fBX509_STORE_CTX_cleanup()\fR, \fBX509_STORE_CTX_free()\fR, \fBX509_STORE_CTX_trusted_stack()\fR, \&\fBX509_STORE_CTX_set_cert()\fR, \fBX509_STORE_CTX_set_chain()\fR, \&\fBX509_STORE_CTX_set0_crls()\fR and \fBX509_STORE_CTX_set0_param()\fR do not return values. .PP \&\fBX509_STORE_CTX_set_default()\fR returns 1 for success or 0 if an error occurred. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBX509_verify_cert\fR\|(3) \&\fBX509_VERIFY_PARAM_set_flags\fR\|(3) .SH "HISTORY" .IX Header "HISTORY" \&\fBX509_STORE_CTX_set0_crls()\fR was first added to OpenSSL 1.0.0
