This structure is used with hashed messages. It is passed to CryptMsgOpenToEncodeif dwMsgTypeis CMSG_ENVELOPED.

Syntax

typedef struct _CMSG_ENVELOPED_ENCODE_INFO {
  DWORD 
cbSize;
  HCRYPTPROV 
hCryptProv;
  CRYPT_ALGORITHM_IDENTIFIER 
HashAlgorithm;
  void* 
pvHashAuxInfo;
} CMSG_ENVELOPED_ENCODE_INFO, *PCMSG_ENVELOPED_ENCODE_INFO;

Members

cbSize

Size of this structure in bytes.

hCryptProv

Specifies a handle to the cryptographic service provider (CSP) that is used to do the hash. The hCryptProvprivate keys are not used.

Unless there is a strong reason for passing in a specific cryptographic provider in hCryptProv, pass zero to use the default RSA or DSS provider to be acquired before doing hash, signature verification, or recipient encryption operations.

HashAlgorithm

CRYPT_ALGORITHM_IDENTIFIERstructure that contains the hash algorithm type and any associated additional parameters.

pvHashAuxInfo

Currently not used and must be set to NULL.

Requirements

Header wincrypt.h
Windows Embedded CE Windows CE .NET 4.0 and later
Windows Mobile Windows Mobile Version 5.0 and later
