asn1_encode_simple_der - API function
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
bytes. Initially tl_len
should contain the size
The complete DER encoding should consist of the value in tl
the provided str
if successful or an error value.
