public class RSAKeyFactory

extends RSAKeyFactory

This class is able to transform RSA-keys and RSA-key specs into a form that can be used with the FlexiProvider.

RSAKeyFactory

public RSAKeyFactory()

Method Detail

generatePublic

public PublicKey generatePublic(KeySpec keySpec)
                         throws InvalidKeySpecException

Converts, if possible, a key specification into a RSAPubKey. Currently the following key specifications are supported: RSAPublicKeySpec, X509EncodedKeySpec.

Overrides:

generatePublic in class KeyFactory

Parameters:

keySpec - the key specification

Returns:

the public RSA key

Throws:

InvalidKeySpecException - if the KeySpec is not supported.

See Also:

RSAPublicKey

generatePrivate

public PrivateKey generatePrivate(KeySpec keySpec)
                           throws InvalidKeySpecException

Converts, if possible, a key specification into a RSAPrivCrtKey or a RSAPrivKey. Currently the following key specifications are supported: RSAPrivateCrtKeySpec, RSAPrivateKeySpec, PKCS8EncodedKeySpec.

Overrides:

generatePrivate in class KeyFactory

Parameters:

keySpec - the key specification

Returns:

the private RSA key

Throws:

InvalidKeySpecException - if the KeySpec is not supported.

See Also:

RSAPrivateCrtKey, RSAPrivateKey

getKeySpec

public KeySpec getKeySpec(Key key,
                          java.lang.Class keySpec)
                   throws InvalidKeySpecException

Converts a given key into a key specification, if possible. Currently the following specifications are supported:

• for RSAPublicKey: X509EncodedKeySpec, RSAPublicKeySpec
• for RSAPrivateKey: PKCS8EncodedKeySpec, RSAPrivateKeySpec
• for RSAPrivateCrtKey: PKCS8EncodedKeySpec, RSAPrivateKeySpec, RSAPrivateCrtKeySpec

Overrides:

getKeySpec in class KeyFactory

Parameters:

key - the key

keySpec - the key specification

Returns:

key specification of the RSA key

Throws:

InvalidKeySpecException - if the specification is not supported.

translateKey

public Key translateKey(Key key)
                 throws InvalidKeyException

Translates a key into a form known by the FlexiProvider. Currently the following "source" keys are supported: RSAPrivateCrtKey, RSAPrivateKey, RSAPublicKey.

Overrides:

translateKey in class KeyFactory

Parameters:

key - the key

Returns:

a key of a known key type

Throws:

InvalidKeyException - if the key is not supported.
