asn1_der_decoding2: API function
NAMEasn1_der_decoding2 - API function
- asn1_node * element
- pointer to an ASN1 structure.
- const void * ider
- vector that contains the DER encoding.
- int * max_ider_len
- pointer to an integer giving the information about the maximal number of bytes occupied by * ider . The real size of the DER encoding is returned through this pointer.
- unsigned int flags
- flags controlling the behaviour of the function.
- char * errorDescription
- null-terminated string contains details when an error occurred.
DESCRIPTIONFill the structure * element with values of a DER encoding string. The structure must just be created with function asn1_create_element().
If ASN1_DECODE_FLAG_ALLOW_PADDING flag is set then the function will ignore padding after the decoded DER data. Upon a successful return the value of * max_ider_len will be set to the number of bytes decoded.
RETURNSASN1_SUCCESS if DER encoding OK, ASN1_ELEMENT_NOT_FOUND if ELEMENT is NULL, and ASN1_TAG_ERROR or ASN1_DER_ERROR if the der encoding doesn't match the structure name (* ELEMENT deleted).
