PKEY_USAGE_PERIOD_NEW(3)   Library Functions Manual   PKEY_USAGE_PERIOD_NEW(3)

NAME
     PKEY_USAGE_PERIOD_new, PKEY_USAGE_PERIOD_free - X.509 certificate private
     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
     differed 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
     Certificate 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.
