NAME

       asn1_get_octet_der - API function

SYNOPSIS

       #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);

ARGUMENTS

       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.

DESCRIPTION

       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

       Returns ASN1_SUCCESS on success, or an error.
