Hi

I am trying to parse a ASN format that has the following structure.
ASNSEQUENCE[C] = 3 elements
  INTEGER = 0
  SEQUENCE[C] = 2 elements
    OBJECT ID = SHA
    NULL = null
  SEQUENCE[C] = 1 elements
    SEQUENCE[C] = 2 elements
      INTEGER = 1
      OCTET STRING = 20 bytes: 98:F7:6A:06:E1...

My input is der encoding of this structure.

I am not sure how to correctly read all the elements inside a SEQUENCE. In
particular, I want to read the digest and the digest algorithm.
 I tried using the method ASN1_seq_unpack_ASN1_TYPE. Can anyone provide
sample codes or provide an explanation on how to parse?

Thanks
Venkat
