Remarks
This class provides the functionality of a key agreement (or key exchange) protocol.
The keys involved in establishing a shared secret are created by one of the key generators (KeyPairGenerator or KeyGenerator), a KeyFactory, or as a result from an intermediate phase of the key agreement protocol.
For each of the correspondents in the key exchange, doPhase needs to be called. For example, if this key exchange is with one other party, doPhase needs to be called once, with the lastPhase flag set to true. If this key exchange is with two other parties, doPhase needs to be called twice, the first time setting the lastPhase flag to false, and the second time setting it to true. There may be any number of parties involved in a key exchange.
Android provides the following KeyAgreement algorithms: <table> <thead> <tr> <th>Algorithm</th> <th>Supported API Levels</th> </tr> </thead> <tbody> <tr> <td>DH</td> <td>1+</td> </tr> <tr> <td>ECDH</td> <td>11+</td> </tr> </tbody> </table>
This algorithm is described in the KeyAgreement section of the Java Cryptography Architecture Standard Algorithm Name Documentation.
Added in 1.4.
