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.
