X509_NAME_add_entry_by_NID() add a field whose name is defined by a string field, an object obj or a NID nid, respectively. The field value to be added is in bytes of length len. If len is -1 then the field length is calculated internally using
strlen(bytes). The type of field is determined by type which can either be a definition of the type of bytes (such as
MBSTRING_ASC) or a standard ASN.1 type (such as
V_ASN1_IA5STRING). The new entry is added to a position determined by loc and set.
X509_NAME_add_entry() adds a copy of an X509_NAME_ENTRY structure ne to name. The new entry is added to a position determined by loc and set. Since a copy of ne is added, ne must be freed up after the call.
X509_NAME_delete_entry() deletes an entry from name at position loc. The deleted entry is returned and must be freed up. The use of string types such as
MBSTRING_UTF8is strongly recommended for the type parameter. This allows the internal code to correctly determine the type of the field and to apply length checks according to the relevant standards. If instead an ASN.1 type is used, no checks are performed and the supplied data in bytes is used directly. In
X509_NAME_add_entry_by_txt() the field string represents the field name using
OBJ_txt2obj(field, 0). The loc and set parameters determine where a new entry should be added. For almost all applications, loc can be set to -1 and set to 0. This adds a new entry to the end of name as a single valued RelativeDistinguishedName (RDN). loc actually determines the index where the new entry is inserted: if it is -1 it is appended. set determines how the new type is added. If it is zero a new RDN is created. If set is -1 or 1 it is added to the previous or next RDN structure respectively. This will then be a multivalued RDN: since multivalue RDNs are very seldom used, set is almost always set to zero.
X509_NAME_add_entry() return 1 for success or 0 if an error occurred.
X509_NAME_delete_entry() returns either the deleted X509_NAME_ENTRY structure or
NULLif an error occurred. In some cases of failure, the reason can be determined with ERR_get_error(3).

X509_NAME_delete_entry() first appeared in SSLeay 0.8.0 and have been available since OpenBSD 2.4.
X509_NAME_add_entry_by_NID() first appeared in OpenSSL 0.9.5 and have been available since OpenBSD 2.7.
V_ASN1_APP_CHOOSEto use a different algorithm to determine field types. Since this form does not understand multicharacter types, performs no length checks, and can result in invalid field types, its use is strongly discouraged.
