Example 12 with KeyAgreement

use of javax.crypto.KeyAgreement in project robovm by robovm.

    try {
        // Although the buffer is big enough (1024 bytes) the shared secret should be placed
        // at offset 1020 thus leaving only 4 bytes for the secret, which is not enough.
        keyAgreement.generateSecret(new byte[1024], 1020);
