Examples of generateSecret()

at.molindo.notify.model.Preferences.generateSecret()
javax.crypto.KeyAgreement.generateSecret()
Generates the shared secret. @return the generated shared secret. @throws IllegalStateException if this key agreement is not complete.
javax.crypto.SecretKeyFactory.generateSecret()
Generate a secret key from the specified key specification. @param keySpec the key specification. @return a secret key. @throws InvalidKeySpecException if the specified key specification cannot be used to generate a secret key.
