asn1_decode_simple_der(3)					     libtasn1						 asn1_decode_simple_der(3)

NAME

       asn1_decode_simple_der - API function

SYNOPSIS

       #include <libtasn1.h>

       int  asn1_decode_simple_der(unsigned int etype, const unsigned char * der, unsigned int der_len, const unsigned char ** str, unsigned int *
       str_len);

ARGUMENTS

       unsigned int etype
		   The type of the string to be encoded (ASN1_ETYPE_)

       const unsigned char * der
		   the encoded string

       unsigned int der_len
		   the bytes of the encoded string

       const unsigned char ** str
		   a pointer to the data

       unsigned int * str_len
		   the length of the data

DESCRIPTION

       Decodes a simple DER encoded type (e.g. a string, which is not constructed).  The output is a pointer inside the der.

RETURNS

       ASN1_SUCCESS if successful or an error value.

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.
