  • Java Cipher.doFinal is returning an unexpected RuntimeException
    when the function is called more than once:
    Exception: java.lang.RuntimeException: Hardware error from call
    CSNDPKD returnCode 8 reasonCode 11000
    The Java 6 API specifically states:
    "Upon finishing, this method resets this cipher object to the
    state it was in when previously initialized via a call to init.
    That is, the object is reset and available to encrypt or decrypt
    (depending on the operation mode that was specified in the call
    to init) more data. "
    The Cipher.doFinal method does not reset data buffers as it
    should.
    KEYWORDS:
    RSA CIPHER DOFINAL CSNDPKD
