NAME
ASN1_item_pack
,
ASN1_item_unpack
— pack an
ASN.1 object into an ASN1_STRING
SYNOPSIS
#include
<openssl/asn1.h>
ASN1_STRING *
ASN1_item_pack
(void *val_in,
const ASN1_ITEM *it, ASN1_STRING
**string_out);
void *
ASN1_item_unpack
(const ASN1_STRING
*string_in, const ASN1_ITEM *it);
DESCRIPTION
ASN1_item_pack
()
encodes the object pointed to by val_in into DER
format using
ASN1_item_i2d(3) and stores
the encoded form in **string_out. If
string_out or *string_out is a
NULL
pointer, a new
ASN1_STRING object is allocated and returned.
ASN1_item_unpack
()
interprets the data in string_in as a DER- or
BER-encoded byte array and decodes one value of the type
it into a newly allocated object using
ASN1_item_d2i(3).
RETURN VALUES
ASN1_item_pack
() returns the modified or
new object or NULL
if memory allocation or encoding
fails.
ASN1_item_unpack
() returns the new object
or NULL
if memory allocation or decoding fails.
