X509_NAME_add_entry_by_txt(3SSL)             OpenSSL             X509_NAME_add_entry_by_txt(3SSL)



NAME
       X509_NAME_add_entry_by_txt, X509_NAME_add_entry_by_OBJ, X509_NAME_add_entry_by_NID,
       X509_NAME_add_entry, X509_NAME_delete_entry - X509_NAME modification functions

SYNOPSIS
        #include <openssl/x509.h>

        int X509_NAME_add_entry_by_txt(X509_NAME *name, const char *field, int type, const unsigned char *bytes, int len, int loc, int set);

        int X509_NAME_add_entry_by_OBJ(X509_NAME *name, ASN1_OBJECT *obj, int type, unsigned char *bytes, int len, int loc, int set);

        int X509_NAME_add_entry_by_NID(X509_NAME *name, int nid, int type, unsigned char *bytes, int len, int loc, int set);

        int X509_NAME_add_entry(X509_NAME *name,X509_NAME_ENTRY *ne, int loc, int set);

        X509_NAME_ENTRY *X509_NAME_delete_entry(X509_NAME *name, int loc);

DESCRIPTION
       X509_NAME_add_entry_by_txt(), X509_NAME_add_entry_by_OBJ() and
       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 ASN1 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 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.

NOTES
       The use of string types such as MBSTRING_ASC or MBSTRING_UTF8 is strongly recommened 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. This is done using
       ASN1_STRING_set_by_NID().

       If instead an ASN1 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 multivalues RDNs are very seldom used set is almost
       always set to zero.

EXAMPLES
       Create an X509_NAME structure:

       "C=UK, O=Disorganized Organization, CN=Joe Bloggs"

        X509_NAME *nm;
        nm = X509_NAME_new();
        if (nm == NULL)
               /* Some error */
        if (!X509_NAME_add_entry_by_txt(nm, "C", MBSTRING_ASC,
                               "UK", -1, -1, 0))
               /* Error */
        if (!X509_NAME_add_entry_by_txt(nm, "O", MBSTRING_ASC,
                               "Disorganized Organization", -1, -1, 0))
               /* Error */
        if (!X509_NAME_add_entry_by_txt(nm, "CN", MBSTRING_ASC,
                               "Joe Bloggs", -1, -1, 0))
               /* Error */

RETURN VALUES
       X509_NAME_add_entry_by_txt(), X509_NAME_add_entry_by_OBJ(), X509_NAME_add_entry_by_NID()
       and X509_NAME_add_entry() return 1 for success of 0 if an error occurred.

       X509_NAME_delete_entry() returns either the deleted X509_NAME_ENTRY structure of NULL if
       an error occurred.

BUGS
       type can still be set to V_ASN1_APP_CHOOSE to 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.
