TrustManagerFactorySpi
abstract class TrustManagerFactorySpi
This class defines the Service Provider Interface (SPI) for the TrustManagerFactory class.
All the abstract methods in this class must be implemented by each cryptographic service provider who wishes to supply the implementation of a particular trust manager factory.
Summary
| Protected methods |
| abstract Array<TrustManager!>! |
Returns one trust manager for each type of trust material.
|
| abstract Unit |
Initializes this factory with a source of certificate authorities and related trust material.
|
| abstract Unit |
Initializes this factory with a source of provider-specific key material.
|
Public constructors
TrustManagerFactorySpi
TrustManagerFactorySpi()
Protected methods
engineGetTrustManagers
protected abstract fun engineGetTrustManagers(): Array<TrustManager!>!
Returns one trust manager for each type of trust material.
| Exceptions |
java.lang.IllegalStateException |
if the factory is not initialized. |
engineInit
protected abstract fun engineInit(ks: KeyStore!): Unit
Initializes this factory with a source of certificate authorities and related trust material.
| Parameters |
ks |
KeyStore!: the key store or null |
| Exceptions |
java.security.KeyStoreException |
if this operation fails |
engineInit
protected abstract fun engineInit(spec: ManagerFactoryParameters!): Unit
Initializes this factory with a source of provider-specific key material.
In some cases, initialization parameters other than a keystore may be needed by a provider. Users of that particular provider are expected to pass an implementation of the appropriate ManagerFactoryParameters as defined by the provider. The provider can then call the specified methods in the ManagerFactoryParameters implementation to obtain the needed information.
| Exceptions |
java.security.InvalidAlgorithmParameterException |
if there is problem with the parameters |
