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 After this call \fBctx\fR is no longer valid.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. .\" Oracle has added the ARC stability level to this manual page .SH ATTRIBUTES See .BR attributes (7) for descriptions of the following attributes: .sp .TS box; cbp-1 | cbp-1 l | l .
