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.

SEE ALSO
     ASN1_item_d2i(3), PKEY_USAGE_PERIOD_new(3), X509_EXTENSION_new(3)

STANDARDS
     RFC 3280: Internet X.509 Public Key Infrastructure Certificate and Cer-
     tificate Revocation List (CRL) Profile, section 4.2.1.4: Private Key
     Usage Period

     RFC 3280 was obsoleted by RFC 5280; see PKEY_USAGE_PERIOD_new(3) for
     details.

HISTORY
     d2i_PKEY_USAGE_PERIOD() and i2d_PKEY_USAGE_PERIOD() first appeared in
     OpenSSL 0.9.2b and have been available since OpenBSD 2.6.
