sun.security.x509.PrivateKeyUsageExtension
| PrivateKeyUsageExtension | | public class PrivateKeyUsageExtension extends Extension implements CertAttrSet(Code) | | This class defines the Private Key Usage Extension.
The Private Key Usage Period extension allows the certificate issuer
to specify a different validity period for the private key than the
certificate. This extension is intended for use with digital
signature keys. This extension consists of two optional components
notBefore and notAfter. The private key associated with the
certificate should not be used to sign objects before or after the
times specified by the two components, respectively.
