CMSG_CMS_SIGNER_INFO (Windows Embedded CE 6.0)

1/6/2010

This structure contains the content of the defined SignerInfo in signed or signed and enveloped messages. In decoding a received message, CryptMsgGetParam is called for each signer to get a CMSG_CMS_SIGNER_INFO structure.

Syntax

typedef struct _CMSG_CMS_SIGNER_INFO {
  DWORD dwVersion;
  CERT_ID SignerId;
  CRYPT_ALGORITHM_IDENTIFIER HashAlgorithm;
  CRYPT_ALGORITHM_IDENTIFIER HashEncryptionAlgorithm;
  CRYPT_DATA_BLOB EncryptedHash;
  CRYPT_ATTRIBUTES AuthAttrs;
  CRYPT_ATTRIBUTES UnauthAttrs;
} CMSG_CMS_SIGNER_INFO, *PCMSG_CMS_SIGNER_INFO;

Members

• dwVersion
  The version of this structure.

• SignerId
  CERT_ID structure identifying the signer's certificate.

• HashAlgorithm
  CRYPT_ALGORITHM_IDENTIFIER structure that specifies the algorithm that is used in generating the hash of a message.

• HashEncryptionAlgorithm
  CRYPT_ALGORITHM_IDENTIFIER structure that specifies the algorithm used to encrypt the hash.

• EncryptedHash
  CRYPT_DATA_BLOB that contains the encrypted hash of the message, the signature.

• AuthAttrs
  CRYPT_ATTRIBUTES structure that contains authenticated attributes of the signer.

• UnauthAttrs
  CRYPT_ATTRIBUTES structure that contains unauthenticated attributes of the signer.
