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

Members

dwVersion

The version of this structure.

Issuer

CERT_NAME_BLOBthat contains the issuer of a certificate with the public key needed to verify a signature.

SerialNumber

CRYPT_INTEGER_BLOBthat contains the serial number of the certificate containing the public key needed to verify a signature. See CERT_INFOfor details.

HashAlgorithm

CRYPT_ALGORITHM_IDENTIFIERstructure that specifies the algorithm used in generating the hash of a message.

HashEncryptionAlgorithm

CRYPT_ALGORITHM_IDENTIFIERstructure that specifies the algorithm used to encrypt the hash.

EncryptedHash

CRYPT_DATA_BLOBthat contains the encrypted hash of the message, the signature.

AuthAttrs

CRYPT_ATTRIBUTESstructure that contains authenticated attributes of the signer.

UnauthAttrs

CRYPT_ATTRIBUTES structure that contains unauthenticated attributes of the signer.

Requirements
