RFC 3280 was obsoleted by RFC 5280, which says: "Section 4.2.1.4
|
|
in RFC 3280, which specified the

|
.Vt 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."
