# DESCRIPTION

ITAV is short for InfoTypeAndValue.

OSSL_CMP_ITAV_new_caCerts() creates an OSSL_CMP_ITAV structure of type caCerts and fills it with a copy of the provided list of certificates. The caCerts argument may be NULL or contain any number of certificates.

OSSL_CMP_ITAV_get0_caCerts() requires that itav has type caCerts. It assigns NULL to *out if there are no CA certificates in itav, otherwise the internal pointer of type STACK_OF(X509) with the certificates present.

OSSL_CMP_ITAV_new_rootCaCert() creates a new OSSL_CMP_ITAV structure of type rootCaCert that includes the optionally given certificate.

OSSL_CMP_ITAV_get0_rootCaCert() requires that itav has type rootCaCert. It assigns NULL to *out if no certificate is included in itav, otherwise the internal pointer to the certificate contained in the infoValue field.

OSSL_CMP_ITAV_new_rootCaKeyUpdate() creates a new OSSL_CMP_ITAV structure of type rootCaKeyUpdate that includes an RootCaKeyUpdateContent structure with the optional newWithNew, newWithOld, and oldWithNew certificates. An RootCaKeyUpdateContent structure is included only if newWithNew is not NULL.

OSSL_CMP_ITAV_get0_rootCaKeyUpdate() requires that itav has infoType rootCaKeyUpdate. If an update of a root CA certificate is included, it assigns to *newWithNew the internal pointer to the certificate contained in the newWithNew infoValue sub-field of itav. If newWithOld is not NULL, it assigns to *newWithOld the internal pointer to the certificate contained in the newWithOld infoValue sub-field of itav. If oldWithNew is not NULL, it assigns to *oldWithNew the internal pointer to the certificate contained in the oldWithNew infoValue sub-field of itav. Each of these pointers will be set to NULL if no root CA certificate update is present or the respective sub-field is not included.

# NOTES

CMP is defined in RFC 4210.

# RETURN VALUES

OSSL_CMP_ITAV_new_caCerts(), OSSL_CMP_ITAV_new_rootCaCert(), and OSSL_CMP_ITAV_new_rootCaKeyUpdate() return a pointer to the new ITAV structure on success, or NULL on error.

OSSL_CMP_ITAV_get0_caCerts(), OSSL_CMP_ITAV_get0_rootCaCert(), and OSSL_CMP_ITAV_get0_rootCaKeyUpdate() return 1 on success, 0 on error.
