    derivedKeys?: DerivedKeys | null

    the sending side's derived keys of a symmetric message (null for None); or give securityOptions instead

    maxChunkCount: number

    0 = unlimited

    maxMessageSize: number

    0 = unlimited

    the security header of every chunk: an AsymmetricAlgorithmSecurityHeader for OpenSecureChannel

    securityMode: MessageSecurityMode

    None, Sign or SignAndEncrypt

    securityOptions?: Partial<SecureMessageData> | null

    the signing and encryption of the chunks: what getOptionsForSymmetricSignAndEncrypt makes for a token, or the asymmetric ones of OpenSecureChannel

    sequenceNumberGenerator: SequenceNumberGenerator

    shared with the channel

    tokenId?: number

    the token of a symmetric message (MSG, CLO); or give securityHeader instead
