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.
