X509_NAME_ENTRY_create_by_OBJ(X509_NAME_ENTRY **ne, const ASN1_OBJECT *obj, int type, const unsigned char *bytes, int len); X509_NAME_new(3). Since part of the information about how several X509_NAME_ENTRY objects combine to form an X.501 Name is stored in the individual X509_NAME_ENTRY objects rather than in the X509_NAME object, any given X509_NAME_ENTRY object can only be used by one X509_NAME object at a time.
X509_NAME_ENTRY_new() allocates and initializes an empty X509_NAME_ENTRY object, representing an ASN.1 RelativeDistinguishedName structure defined in RFC 5280 section 126.96.36.199, but containing not more than one type-value-pair.
X509_NAME_ENTRY_free() frees ne and the type and value contained in it.
X509_NAME_ENTRY_get_object() retrieves the field type of ne in an ASN1_OBJECT structure.
X509_NAME_ENTRY_get_data() retrieves the field value of ne in an ASN1_STRING structure. These two functions can be used to examine an X509_NAME_ENTRY object as returned by X509_NAME_get_entry(3).
X509_NAME_ENTRY_set() retrieves the index of the X.501 RelativeDistinguishedName (RDN) that ne is part of in the X.501 Name object using it. The first RDN has index 0. If an RDN consists of more than one X509_NAME_ENTRY object, they all share the same index. In practice, RDNs containing more than one type-value-pair are rarely used, so if an X509_NAME *name object uses ne, then
X509_NAME_ENTRY_set(ne) usually agrees with
sk_X509_NAME_ENTRY_find(name->entries, ne), but when multi-pair RDNs are used, it may be smaller.
X509_NAME_ENTRY_set_object() sets the field type of ne to obj.
X509_NAME_ENTRY_set_data() sets the field value of ne to string type type and the value determined by bytes and len.
X509_NAME_ENTRY_create_by_OBJ() create and return an X509_NAME_ENTRY structure. Except for
X509_NAME_ENTRY_get_data(), these functions are rarely used because X509_NAME_ENTRY structures are almost always part of X509_NAME structures and the functions described in X509_NAME_add_entry_by_txt(3) 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 described in X509_NAME_add_entry_by_txt(3). So for example type can be set to
MBSTRING_ASC, but in the case of
X509_NAME_ENTRY_set_data() the field type must be set first so the relevant field information can be looked up internally.
X509_NAME_ENTRY_new() function returns a valid X509_NAME_ENTRY structure if successful; otherwise
NULLis returned and an error code can be retrieved with ERR_get_error(3).
X509_NAME_ENTRY_get_object() returns a valid ASN1_OBJECT structure if it is set or
NULLif an error occurred.
X509_NAME_ENTRY_get_data() returns a valid ASN1_STRING structure if it is set or
NULLif an error occurred.
X509_NAME_ENTRY_set() returns the zero-based index of the RDN ne is used in, or 0 if ne is not yet used by any X509_NAME object. The
X509_NAME_ENTRY_set_object() function returns 1 if successful; otherwise 0 is returned and an error code can be retrieved with ERR_get_error(3).
X509_NAME_ENTRY_set_data() returns 1 on success or 0 on error. In some cases of failure, the reason can be determined with ERR_get_error(3).
X509_NAME_ENTRY_create_by_OBJ() return a valid X509_NAME_ENTRY structure on success or
NULLif an error occurred. In some cases of failure, the reason can be determined with ERR_get_error(3). OBJ_nid2obj(3), X509_NAME_add_entry(3), X509_NAME_get_entry(3), X509_NAME_new(3)
X509_NAME_ENTRY_free() first appeared in SSLeay 0.5.1.
X509_NAME_ENTRY_create_by_OBJ() first appeared in SSLeay 0.8.0. These functions have been available since OpenBSD 2.4.
X509_NAME_ENTRY_create_by_txt() first appeared in OpenSSL 0.9.5 and has been available since OpenBSD 2.7.
X509_NAME_ENTRY_set() first appeared in OpenSSL 1.1.0 and has been available since OpenBSD 6.3.
X509_NAME_ENTRY_set() does not set anything. Something like “X509_NAME_ENTRY_get_set” would have been a better name.
