Constructor Detail

ECDH

public ECDH()

Elliptic Curve Diffie-Hellman KeyAgreement Algorithm is not supported in Gemini product.

Method Detail

engineInit

protected final void engineInit(Key key,
                                AlgorithmParameterSpec params)
                         throws InvalidKeyException,
                                InvalidAlgorithmParameterException

Elliptic Curve Diffie-Hellman KeyAgreement Algorithm is not supported in Gemini product.

Overrides:

engineInit in class KeyAgreementSpi

Following copied from class: com.motorola.iden.crypto.KeyAgreementSpi

Parameters:

key - the party's private information. For example, in the case of the Diffie-Hellman key agreement, this would be the party's own Diffie-Hellman private key.

params - the key agreement parameters

Throws:

InvalidKeyException - if the given key is inappropriate for this key agreement, e.g., is of the wrong type or has an incompatible algorithm type.

InvalidAlgorithmParameterException - if the given parameters are inappropriate for this key agreement.

engineDoPhase

protected final Key engineDoPhase(Key key,
                                  boolean lastPhase)
                           throws InvalidKeyException

Elliptic Curve Diffie-Hellman KeyAgreement Algorithm is not supported in Gemini product.

Overrides:

engineDoPhase in class KeyAgreementSpi

Following copied from class: com.motorola.iden.crypto.KeyAgreementSpi

Parameters:

key - the key for this phase. For example, in the case of Diffie-Hellman between 2 parties, this would be the other party's Diffie-Hellman public key.

lastPhase - flag which indicates whether or not this is the last phase of this key agreement.

Returns:

the (intermediate) key resulting from this phase, or null if this phase does not yield a key

Throws:

InvalidKeyException - if the given key is inappropriate for this phase.

engineGenerateSecret

protected final byte[] engineGenerateSecret()

Elliptic Curve Diffie-Hellman KeyAgreement Algorithm is not supported in Gemini product.

Overrides:

engineGenerateSecret in class KeyAgreementSpi

Following copied from class: com.motorola.iden.crypto.KeyAgreementSpi

Returns:

the new buffer with the shared secret
