_OFFLOAD_SECURITY_ASSOCIATION structure

-description

The OFFLOAD_SECURITY_ASSOCIATION structure specifies a single security association (SA).

-struct-fields

-field Operation

The Internet Protocol security (IPsec) operation for which the SA is to be used. The following operations are supported:

AUTHENTICATE

The SA will be used for authentication (integrity checking).

ENCRYPT

The SA will be used for encryption/decryption (confidentiality).

-field SPI

The Security Parameters Index (SPI) for the SA.

-field IntegrityAlgo

The integrity (authentication) algorithm for the SA, formatted as an OFFLOAD_ALGO_INFO structure.

-field ConfAlgo

The confidentiality (encryption/decryption) algorithm for the SA, formatted as an OFFLOAD_ALGO_INFO structure.

-field Reserved

This member is reserved.

-remarks

The OFFLOAD_SECURITY_ASSOCIATION structure is used with the OID_TCP_TASK_IPSEC_ADD_SA and OID_TCP_TASK_IPSEC_ADD_UDPESP_SA OIDs.
