/**
|
* This class provides an interface for generating self-signed certificates and
|
* certificate signing requests, and for importing, exporting, and deleting
|
* certificates from a key store. It supports JKS, PKCS11, and PKCS12 key store
|
* types.
|
* <BR><BR>
|
* Note that for some operations, particularly those that require updating the
|
* contents of a key store (including generating certificates and/or certificate
|
* signing requests, importing certificates, or removing certificates), this
|
* class relies on the keytool utility provided with Sun's implementation of the
|
* Java runtime environment. It will perform the associated operations by
|
* invoking the appropriate command. It is possible that the keytool command
|
* will not exist in all Java runtime environments, especially those not created
|
* by Sun. In those cases, it will not be possible to invoke operations that
|
* require altering the contents of the key store. Therefore, it is strongly
|
* recommended that any code that may want to make use of this facility should
|
* first call {@code mayUseCertificateManager} and if it returns {@code false}
|
* the caller should gracefully degrade and suggest that the user perform the
|
* operation manually.
