IPSEC_CIPHER_TRANSFORM_ID0 structure (ipsectypes.h)

The IPSEC_CIPHER_TRANSFORM_ID0 structure specifies information used to uniquely identify the encryption algorithm used in an IPsec SA.

Syntax

typedef struct IPSEC_CIPHER_TRANSFORM_ID0_ {
  IPSEC_CIPHER_TYPE   cipherType;
  IPSEC_CIPHER_CONFIG cipherConfig;
} IPSEC_CIPHER_TRANSFORM_ID0;

Members

cipherType

The type of the encryption algorithm as specified by IPSEC_CIPHER_TYPE.

cipherConfig

Additional configuration information for the encryption algorithm as specified by IPSEC_CIPHER_CONFIG which maps to a UINT8.
