Members

  • dwProtocol
    Specifies the protocol used to establish this connection. The following table shows valid constants for this member.
    Value Description
    SP_PROT_TLS1_CLIENT Transport Layer Security 1.0 client-side.
    SP_PROT_TLS1_SERVER Transport Layer Security 1.0 server-side.
    SP_PROT_SSL3_CLIENT Secure Sockets Layer 3.0 client-side.
    SP_PROT_SSL3_SERVER Secure Sockets Layer 3.0 server-side.
    SP_PROT_SSL2_CLIENT Secure Sockets Layer 2.0 client-side. Superseded by SP_PROT_TLS1_CLIENT.
    SP_PROT_SSL2_SERVER Secure Sockets Layer 2.0 server-side. Superseded by SP_PROT_TLS1_SERVER.
  • aiCipher
    Algorithm identifier (ALG_ID) for the bulk encryption cipher used by this connection. The following table shows the valid constants for this member.
    Value Description
    CALG_RC2 RC2 block encryption algorithm.
    CALG_RC4 RC4 stream encryption algorithm.
    CALG_DES DES encryption algorithm.
    CALG_SKIPJACK Skipjackblock encryption algorithm (FORTEZZA).
    0 (Zero) No encryption.
  • dwCipherStrength
    Specifies the strength of the bulk encryption cipher, in bits. Can be one of the following values: 0, 40, 56, 80, 128, or 168.
  • aiHash
    ALG_ID indicating the hash used for generating message authentication codes (MACs). The following table describes the valid constants for this member.
    Value Description
