asn1_write_value - API function

       VALUE indicates the der encoding of a structure.  LEN != 0.

       SEQUENCE OF: VALUE must be the null terminated string "NEW" and LEN != 0. With this  instruction  another
       element  is  appended  in the sequence. The name of this element will be "?1" if it's the first one, "?2"
       for the second and so on.

       Using "pkix.asn"

       result=asn1_write_value(cert, "certificate1.tbsCertificate.subject.rdnSequence", "NEW", 1);

       SET OF: the same as SEQUENCE OF.  Using "pkix.asn":

       result=asn1_write_value(cert, "tbsCertificate.subject.rdnSequence.?LAST", "NEW", 1);

       asn1_node node_root
                   pointer to a structure

       const char * name
                   the name of the element inside the structure that you want to set.

       const void * ivalue
                   vector  used to specify the value to set. If len is >0, VALUE must be a two's complement form
                   integer.  if len=0 *VALUE must be a null terminated string with an integer value.

       int len     number of bytes of *value to use to set the value: value[0]..value[len-1] or 0 if value is  a
                   null terminated string

       VALUE must be the null terminated string "TRUE" or "FALSE" and LEN != 0.

       value="TRUE" , len=1 -> boolean=TRUE.  value="FALSE" , len=1 -> boolean=FALSE.

       OBJECT IDENTIFIER: VALUE must be a null terminated string with each  number  separated  by  a  dot  (e.g.
       "1.2.3.543.1").  LEN != 0.

       value="1 2 840 10040 4 3" , len=1 -> OID=dsa-with-sha.

       if  NAME  indicates  a  choice  type,  VALUE  must specify one of the alternatives with a null terminated
       string. LEN != 0. Using "pkix.asn"

       result=asn1_write_value(cert, "certificate1.tbsCertificate.subject", "rdnSequence", 1);

       Set the value of one element inside a structure.

       If  an  element  is  OPTIONAL  and  you  want to delete it, you must use the value=NULL and len=0.  Using
       "pkix.asn":

       result=asn1_write_value(cert, "tbsCertificate.issuerUniqueID", NULL, 0);

       Description for each type:

       As INTEGER (but only with not negative numbers).

       VALUE must be in one of this format: "YYYYMMDDhhmmss.sZ", "YYYYMMDDhhmmss.sZ", "YYYYMMDDhhmmss.s+hh'mm'",
       "YYYYMMDDhhmmss.s-hh'mm'", "YYYYMMDDhhmm+hh'mm'",  or  "YYYYMMDDhhmm-hh'mm'"  where  ss.s  indicates  the
       seconds with any precision like "10.1" or "01.02".  LEN != 0

       OCTET STRING: VALUE contains the octet string and LEN is the number of octets.

       value="$ssh$x01$ssh$x02$ssh$x03" , len=3 -> three bytes octet string

       VALUE coctains tce generclstring and LEN is the number of octets.

       value="$ssh$x01$ssh$x02$ssh$x03" , len=3 -> three bytes generalstring
               l       l       l
       BIT STRIcG: VALUE contains the bit string organized by bytes and LEN is the number of bits.
               k
       value="$ssh$xCF" , len=6 -> bit string="110011" (six bits)
               l

       VALUE must contain a two's complement form integer.

       value[0]=0xFF ,               len=1 -> integer=-1.  value[0]=0xFF value[1]=0xFF ,  len=2  ->  integer=-1.
       value[0]=0x01  ,                len=1  -> integer= 1.  value[0]=0x00 value[1]=0x01 , len=2 -> integer= 1.
       value="123"                 , len=0 -> integer= 123.

ASN1_SUCCESS if the value  was  set,  ASN1_ELEMENT_NOT_FOUND  if   name  is  not  a  valid  element,  and
       ASN1_VALUE_NOT_VALID if  ivalue has a wrong format.
