This structure is used with hashed messages. It is passed to CryptMsgOpenToEncode if dwMsgType is CMSG_ENVELOPED.


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

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 hCryptProv private 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_IDENTIFIER structure that contains the hash algorithm type and any associated additional parameters.

pvHashAuxInfo

Currently not used and must be set to NULL.
