12 ret_len, unsigned char * str, int str_size, int * str_len);
13
15 const unsigned char * der
16 DER data to decode containing the OCTET SEQUENCE.
17
18 int der_len The length of the der data to decode.
19
20 int * ret_len
21 Output variable containing the encoded length of the DER
22 data.
23
24 unsigned char * str
25 Pre-allocated output buffer to put decoded OCTET SEQUENCE
26 in.
27
28 int str_size
29 Length of pre-allocated output buffer.
30
31 int * str_len
32 Output variable containing the length of the contents of
33 the OCTET SEQUENCE.
34
36 Extract an OCTET SEQUENCE from DER data. Note that this function ex‐
37 pects the DER data past the tag field, i.e., the length and content
38 octets.
