Examples of java.security.cert.X509Certificate.checkValidity()

java.security.cert.X509Certificate.checkValidity()
Checks that the certificate is currently valid. It is if the current date and time are within the validity period given in the certificate.
The validity period consists of two date/time values: the first and last dates (and times) on which the certificate is valid. It is defined in ASN.1 as:
```
 validity             Validity Validity ::= SEQUENCE { notBefore      CertificateValidityDate, notAfter       CertificateValidityDate }
 CertificateValidityDate ::= CHOICE { utcTime        UTCTime, generalTime    GeneralizedTime } 
```
@exception CertificateExpiredException if the certificate has expired. @exception CertificateNotYetValidException if the certificate is notyet valid.
