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).

m_internalSynchronization

private java.lang.Object m_internalSynchronization

m_protocolWithTimestamp

private boolean m_protocolWithTimestamp

m_paymentRequired

private boolean m_paymentRequired

m_firstMixSymmetricCipher

private SymCipher m_firstMixSymmetricCipher

m_chainProtocolWithFlowControl

private boolean m_chainProtocolWithFlowControl

m_fixedRatioChannelsDescription

private FixedRatioChannelsDescription m_fixedRatioChannelsDescription

m_mixParameters
