This package provides all the classes and all the interfaces needed to generate, administer and verify
X.509 certificates.
Functionality for parsing certificate, extracting information from them, validating and
verifying the information they contains are provided.
Exception are generated mainly for three reasons:
- if the certificate's encoding is broken
(CertificateEncodingException)
- if the certificate's time stamp is not valid
(CertificateExpiredException)
- or if the validation's path is false (CertPathValidatorException).
The functionality to check the different entries and extension fields of X.509 certificates are also provided.
