Class KeychainEcPrivateKey

java.lang.Object

com.entrust.toolkit.credentials.KeychainPrivateKey

com.entrust.toolkit.credentials.KeychainEcPrivateKey

All Implemented Interfaces:

com.entrust.toolkit.security.provider.EntrustPrivateKey, java.io.Serializable, java.security.interfaces.ECKey, java.security.interfaces.ECPrivateKey, java.security.Key, java.security.PrivateKey, javax.security.auth.Destroyable

public class KeychainEcPrivateKey
extends KeychainPrivateKey
implements java.security.interfaces.ECPrivateKey

The KeychainEcPrivateKey models an Elliptic curve private key that resides in the Apple keychain. The toolkit should be able to use this key to perform any regular toolkit operations that utilize an EC key, without the toolkit having to know the details of the Ec operations. NoteThis key is limited by the Ec curve types supported by the Apple Keychain, so it is possible the set of keychain curves will not mirror that of the curves available natively in the Java toolkit.

Since:

Java toolkit 9.0

Constructor Detail

KeychainEcPrivateKey

public KeychainEcPrivateKey(KeychainKey keychainkey)
                     throws KeychainException

The constructor for this EC Keychain Key

Parameters:

keychainkey - The KeychainKey containing the attributes of the key

Throws:

KeychainException

Method Detail

getParams

public java.security.spec.ECParameterSpec getParams()

Return the ECParameter spec used for this Elliptic curve

Specified by:

getParams in interface java.security.interfaces.ECKey

getS

public java.math.BigInteger getS()

Specified by:

getS in interface java.security.interfaces.ECPrivateKey

Returns:

the private S value from the elliptic curve. Since this key represents a private value for a key that resides in the Keychain, return this value is not possible and represents an access violation. A Security Exception is thrown.

getKeyLength

public int getKeyLength()

Returns:

the key length of the EC key

getAlgorithm

public java.lang.String getAlgorithm()

Returns the standard algorithm name for this key, which is "EC".

Specified by:

getAlgorithm in interface java.security.Key

Specified by:

getAlgorithm in class KeychainPrivateKey

Returns:

the standard name of the algorithm for this key
