asn1_get_octet_der - API function


#include <libtasn1.h>

int asn1_get_octet_der(const unsigned char * der, int der_len, int * ret_len, unsigned char * str, int str_size, int * str_len);


const unsigned char * der
DER data to decode containing the OCTET SEQUENCE.
int der_len
The length of the der data to decode.
int * ret_len
Output variable containing the encoded length of the DER data.
unsigned char * str
Pre-allocated output buffer to put decoded OCTET SEQUENCE in.
int str_size
Length of pre-allocated output buffer.
int * str_len
Output variable containing the length of the contents of the OCTET SEQUENCE.


Extract an OCTET SEQUENCE from DER data. Note that this function expects the DER data past the tag field, i.e., the length and content octets.


Returns ASN1_SUCCESS on success, or an error.
