NAME

     PKEY_USAGE_PERIOD_new, PKEY_USAGE_PERIOD_free -- X.509 certificate pri-
     vate key usage period extension


SYNOPSIS

     #include <openssl/x509v3.h>

     PKEY_USAGE_PERIOD *
     PKEY_USAGE_PERIOD_new(void);

     void
     PKEY_USAGE_PERIOD_free(PKEY_USAGE_PERIOD *period);


DESCRIPTION

     PKEY_USAGE_PERIOD_new() allocates and initializes an empty
     PKEY_USAGE_PERIOD object, representing an ASN.1 PrivateKeyUsagePeriod
     structure defined in RFC 3280 section 4.2.1.4.  It could be used in X509
     certificates to specify a validity period for the private key that dif-
     fered from the validity period of the certificate.

     PKEY_USAGE_PERIOD_free() frees period.


RETURN VALUES

     PKEY_USAGE_PERIOD_new() returns the new PKEY_USAGE_PERIOD object or NULL
     if an error occurs.

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, which says: "Section 4.2.1.4 in RFC
     3280, which specified the PrivateKeyUsagePeriod certificate extension but
     deprecated its use, was removed.  Use of this ISO standard extension is
     neither deprecated nor recommended for use in the Internet PKI."


HISTORY

     PKEY_USAGE_PERIOD_new() and PKEY_USAGE_PERIOD_free() first appeared in
     OpenSSL 0.9.2b and have been available since OpenBSD 2.6.
