This structure contains the content of the PKCS #7 defined SignerInfo in signed messages. In decoding a received message, CryptMsgGetParam is called for each signer to get a CMSG_SIGNER_INFO structure.

typedef struct _CMSG_SIGNER_INFO {  DWORD dwVersion;  CERT_NAME_BLOB Issuer;  CRYPT_INTEGER_BLOB SerialNumber;  CRYPT_ALGORITHM_IDENTIFIER HashAlgorithm;  CRYPT_ALGORITHM_IDENTIFIER HashEncryptionAlgorithm;  CRYPT_DATA_BLOB EncryptedHash;  CRYPT_ATTRIBUTES AuthAttrs;  CRYPT_ATTRIBUTES UnauthAttrs;} CMSG_SIGNER_INFO, *PCMSG_SIGNER_INFO;

Members

  • dwVersion
    The version of this structure.
  • Issuer
    CERT_NAME_BLOB that contains the issuer of a certificate with the public key needed to verify a signature.
  • SerialNumber
    CRYPT_INTEGER_BLOB that contains the serial number of the certificate containing the public key needed to verify a signature. See CERT_INFO for details.
  • HashAlgorithm
    CRYPT_ALGORITHM_IDENTIFIER structure that specifies the algorithm 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.

Requirements

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