Field Detail

m_mixCascadeCertificateLock

private int m_mixCascadeCertificateLock

Stores the lock on the certificate used by the mixcascade to sign all cascade related messages, like the MixCascade or MixCascadeStatus structures. The certificate will be stored within the signature verification certificate store until the lock is released (done when the connection to the mixcascade is closed).
