public abstract KeyStore getKeyStore() throws KeyStoreException
KeyStoreException
- if an error occured during the
operation, for example if the KeyStore could not be
instantiated or loadedpublic abstract KeyStore.ProtectionParameter getProtectionParameter(String alias) throws KeyStoreException
Entry
with the given alias.
The getKeyStore
method must be invoked before this
method may be called.
alias
- the alias of the KeyStore entry
Entry
with the given alias.
NullPointerException
- if alias is null
KeyStoreException
- if an error occured during the
operation
IllegalStateException
- if the getKeyStore method has
not been invoked prior to calling this methodpublic static KeyStore.Builder newInstance(KeyStore keyStore, KeyStore.ProtectionParameter protectionParameter)
keyStore
, the getProtectionParameter() method will
return protectionParameters
.
This is useful if an existing KeyStore object needs to be used with Builder-based APIs.
keyStore
- the KeyStore to be encapsulatedprotectionParameter
- the ProtectionParameter used to
protect the KeyStore entries
NullPointerException
- if keyStore or
protectionParameters is null
IllegalArgumentException
- if the keyStore has not been
initializedpublic static KeyStore.Builder newInstance(String type, Provider provider, File file, KeyStore.ProtectionParameter protection)
The first call to the getKeyStore()
method on the returned
builder will create a KeyStore of type type
and call
its load()
method.
The inputStream
argument is constructed from
file
.
If protection
is a
PasswordProtection
, the password is obtained by
calling the getPassword
method.
Otherwise, if protection
is a
CallbackHandlerProtection
, the password is obtained
by invoking the CallbackHandler.
Subsequent calls to getKeyStore()
return the same object
as the initial call. If the initial call to failed with a
KeyStoreException, subsequent calls also throw a
KeyStoreException.
The KeyStore is instantiated from provider
if
non-null. Otherwise, all installed providers are searched.
Calls to getProtectionParameter()
will return a PasswordProtection
object encapsulating the password that was used to invoke the
load
method.
Note that the getKeyStore()
method is executed
within the AccessControlContext
of the code invoking this
method.
type
- the type of KeyStore to be constructedprovider
- the provider from which the KeyStore is to
be instantiated (or null)file
- the File that contains the KeyStore dataprotection
- the ProtectionParameter securing the KeyStore data
NullPointerException
- if type, file or protection is null
IllegalArgumentException
- if protection is not an instance
of either PasswordProtection or CallbackHandlerProtection; or
if file does not exist or does not refer to a normal filepublic static KeyStore.Builder newInstance(String type, Provider provider, KeyStore.ProtectionParameter protection)
Each call to the getKeyStore()
method on the returned
builder will return a new KeyStore object of type type
.
Its load()
method is invoked using a
LoadStoreParameter
that encapsulates
protection
.
The KeyStore is instantiated from provider
if
non-null. Otherwise, all installed providers are searched.
Calls to getProtectionParameter()
will return protection
.
Note that the getKeyStore()
method is executed
within the AccessControlContext
of the code invoking this
method.
