CMSG_RC4_AUX_INFO structure

The CMSG_RC4_AUX_INFO structure contains the bit length of the key for RC4 encryption algorithms. The pvEncryptionAuxInfo member in CMSG_ENVELOPED_ENCODE_INFO can be set to point to an instance of this structure.

Syntax


typedef struct _CMSG_RC4_AUX_INFO {
  DWORD cbSize;
  DWORD dwBitLen;
} CMSG_RC4_AUX_INFO, *PCMSG_RC4_AUX_INFO;

Members

cbSize

Size of this structure in bytes.

dwBitLen

Determines the RC4 salt length. If set to CMSG_RC4_NO_SALT_FLAG, no salt is generated. For any other value, (128 - the length set) /8 bytes of salt are generated and encoded as an OCTET STRING in the algorithm parameters field.
