The CCAPI data structure. This structure is similar to a krb5_data structure. In a v5 credentials structure, cc_data structures are used to store tagged variable-length binary data. Specifically, for cc_credentials_v5.ticket and cc_credentials_v5.second_ticket, the cc_data.type field must be zero. For the cc_credentials_v5.addresses, cc_credentials_v5.authdata, and cc_credentials_v5.keyblock, the cc_data.type field should be the address type, authorization data type, and encryption type, as defined by the Kerberos v5 protocol definition.
