NAME
asn1_encode_simple_der - API function
SYNOPSIS
#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);ARGUMENTS
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
DESCRIPTION
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 .
RETURNS
ASN1_SUCCESS if successful or an error value.
