Constructor Details

AbstractPkiCredentialContainer

public AbstractPkiCredentialContainer(Provider provider)

Constructor.

Parameters:

provider - the provider that is used to create and manage keys

Method Details

generateAlias

protected BigInteger generateAlias()

Overridable function to generate the unique alias for each generated key.

Returns:

BigInteger key alias

cleanup

public void cleanup()
             throws PkiCredentialContainerException

Traverses through all credentials in the multi credential key store and delets the expired ones.

Specified by:

cleanup in interface PkiCredentialContainer

Throws:

PkiCredentialContainerException - error performing cleanup

isExpired

protected boolean isExpired(String alias)
                     throws PkiCredentialContainerException

Checks if the entry identified with alias is expired.

Parameters:

alias - the key entry alias

Returns:

true if the entry has expired, and false otherwise

Throws:

PkiCredentialContainerException - for errors getting the entry

setKeyValidity

public void setKeyValidity(Duration keyValidity)

Assigns the duration for the validity of generated credentials.

If supplied with null the generated key pairs will never expire. In these cases each generated credential must be manually deleted using PkiCredentialContainer.deleteCredential(String).

Specified by:

setKeyValidity in interface PkiCredentialContainer

Parameters:

keyValidity - the validity

getKeyValidity

protected Duration getKeyValidity()

Gets the key validity. A value of null means that credentials never expire.

Returns:

the validity, or null

setSupportedKeyTypes

public void setSupportedKeyTypes(List<String> supportedKeyTypes)

Assigns the key types that this container supports. The default is DEFAULT_SUPPORTED_KEY_TYPES.

Specified by:

setSupportedKeyTypes in interface PkiCredentialContainer

Parameters:

supportedKeyTypes - a list of supported key types

getProvider

protected Provider getProvider()

Gets the security provider used by the container.

Returns:

the provider

getKeyGeneratorFactory

protected KeyPairGeneratorFactory getKeyGeneratorFactory(String keyTypeName)
                                                  throws NoSuchAlgorithmException

Gets a KeyPairGeneratorFactory that can be used to generate key pairs given the supplied keyTypeName.

Parameters:

keyTypeName - the key type name

Returns:

a KeyPairGeneratorFactory

Throws:

NoSuchAlgorithmException - if no match is found
