#include <libtasn1.h>
int asn1_encode_simple_der(unsigned int etype, const unsigned char *
str, unsigned int str_len, unsigned char * tl, unsigned int *
tl_len);
unsigned int etype
The type of the string to be encoded (ASN1_ETYPE_)
const unsigned char * str
the string data.
unsigned int str_len
the string length
unsigned char * tl
the encoded tag and length
unsigned int * tl_len
the bytes of the tl field
Creates the DER encoding for various simple ASN.1 types like strings
etc. It stores the tag and length in tl , which should have space
for at least ASN1_MAX_TL_SIZE bytes. Initially tl_len should contain
the size of tl .
The complete DER encoding should consist of the value in tl appended
with the provided str .
ASN1_SUCCESS if successful or an error value.
