NAME
d2i_PKEY_USAGE_PERIOD,
i2d_PKEY_USAGE_PERIOD —
decode and encode X.509 key usage
period extensions
SYNOPSIS
#include
<openssl/x509v3.h>
PKEY_USAGE_PERIOD *
d2i_PKEY_USAGE_PERIOD(PKEY_USAGE_PERIOD
**val_out, const unsigned char **der_in,
long length);
int
i2d_PKEY_USAGE_PERIOD(PKEY_USAGE_PERIOD
*val_in, unsigned char **der_out);
DESCRIPTION
d2i_PKEY_USAGE_PERIOD()
and
i2d_PKEY_USAGE_PERIOD()
decode and encode an ASN.1 PrivateKeyUsagePeriod
structure defined in RFC 3280 section 4.2.1.4. For details about the
semantics, examples, caveats, and bugs, see
ASN1_item_d2i(3).
RETURN VALUES
d2i_PKEY_USAGE_PERIOD() returns a
PKEY_USAGE_PERIOD object or
NULL if an error occurs.
i2d_PKEY_USAGE_PERIOD() returns the number
of bytes successfully encoded or a negative value if an error occurs.
