CMSG_HASHED_ENCODE_INFO (Windows CE 5.0)

Send Feedback

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;

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 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.

Requirements

OS Versions: Windows CE .NET 4.0 and later.
Header: Wincrypt.h.
