X509_NAME_ENTRY utility functions
Synopsis
#include <openssl/x509.h> ASN1_OBJECT *X509_NAME_ENTRY_get_object(const X509_NAME_ENTRY *ne); ASN1_STRING *X509_NAME_ENTRY_get_data(const X509_NAME_ENTRY *ne); int X509_NAME_ENTRY_set_object(X509_NAME_ENTRY *ne, const ASN1_OBJECT *obj); int X509_NAME_ENTRY_set_data(X509_NAME_ENTRY *ne, int type, const unsigned char *bytes, int len); X509_NAME_ENTRY *X509_NAME_ENTRY_create_by_txt(X509_NAME_ENTRY **ne, const char *field, int type, const unsigned char *bytes, int len); X509_NAME_ENTRY *X509_NAME_ENTRY_create_by_NID(X509_NAME_ENTRY **ne, int nid, int type, const unsigned char *bytes, int len); X509_NAME_ENTRY *X509_NAME_ENTRY_create_by_OBJ(X509_NAME_ENTRY **ne, const ASN1_OBJECT *obj, int type, const unsigned char *bytes, int len);
Description
X509_NAME_ENTRY_get_object() retrieves the field name of ne in and ASN1_OBJECT structure.
X509_NAME_ENTRY_get_data() retrieves the field value of ne in and ASN1_STRING structure.
X509_NAME_ENTRY_set_object() sets the field name of ne to obj.
X509_NAME_ENTRY_set_data() sets the field value of ne to string type type and value determined by bytes and len.
X509_NAME_ENTRY_create_by_txt(), X509_NAME_ENTRY_create_by_NID() and X509_NAME_ENTRY_create_by_OBJ() create and return an X509_NAME_ENTRY structure.
Notes
X509_NAME_ENTRY_get_object() and X509_NAME_ENTRY_get_data() can be used to examine an X509_NAME_ENTRY function as returned by X509_NAME_get_entry() for example.
X509_NAME_ENTRY_create_by_txt(), X509_NAME_ENTRY_create_by_OBJ(), X509_NAME_ENTRY_create_by_NID() and X509_NAME_ENTRY_set_data() are seldom used in practice because X509_NAME_ENTRY structures are almost always part of X509_NAME structures and the corresponding X509_NAME functions are typically used to create and add new entries in a single operation.
The arguments of these functions support similar options to the similarly named ones of the corresponding X509_NAME functions such as X509_NAME_add_entry_by_txt(). So for example type can be set to MBSTRING_ASC but in the case of X509_set_data() the field name must be set first so the relevant field information can be looked up internally.
Return Values
X509_NAME_ENTRY_get_object() returns a valid ASN1_OBJECT structure if it is set or NULL if an error occurred.
X509_NAME_ENTRY_get_data() returns a valid ASN1_STRING structure if it is set or NULL if an error occurred.
X509_NAME_ENTRY_set_object() and X509_NAME_ENTRY_set_data() return 1 on success or 0 on error.
X509_NAME_ENTRY_create_by_txt(), X509_NAME_ENTRY_create_by_NID() and X509_NAME_ENTRY_create_by_OBJ() return a valid X509_NAME_ENTRY on success or NULL if an error occurred.
