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 .
