    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 Superseded by SP_PROT_TLS1_CLIENT.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 Superseded by SP_PROT_TLS1_SERVER.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_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

    CALG_MD5

    MD5 hashing algorithm.

    CALG_SHA

    SHA hashing algorithm.

  • dwHashStrength
    Specifies the strength of the hash, in bits: 128 or 160.
  • aiExch
    ALG_ID indicating the key exchange algorithm used to generate the shared master secret. The following table describes the valid constants for this member.

    Value Description
